Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation application of U.S.
application Ser. No. 16/692,730, filed Nov. 22, 2019, which is a
continuation application of U.S. application Ser. No. 15/197,752,
filed Jun. 29, 2016, which claims priority to U.S. Provisional
Application No. 62/186,240, filed Jun. 29, 2015, all of which are
incorporated by reference herein in their entirety.
FIELD
[0002] The present disclosure relates to fragrance compositions
comprising one or more musk or fragrance accords. The compositions
can be administered to reduce or inhibit a subject's response to
stress.
BACKGROUND
[0003] Stress is the human body's reaction to internal or external
stimuli. It is well documented that stress typically causes a
negative impact on a person's mental and physical health. Mental
and physical symptoms of stress may include, but are not limited
to, moodiness, irritability or short temper, agitation, inability
to relax, general unhappiness, aches and pains, diarrhea or
constipation, indigestion, nausea, dizziness, chest pain, and/or
rapid heartbeat. Long-term, or chronic stress has been linked to
anxiety, depression, heart problems, weight gain, sleep disorders,
and memory and concentration impairment. Numerous pharmaceutical
remedies exist to treat or lessen these stress responses, however
there remains a need for alternative remedies and solutions.
[0004] Aromatherapy is a known practice for treating stress and
promoting relaxation using essential oils. However, fragrances
comprise a variety of compounds, which can lose their individual
scent identity when combined with other compounds. With such
mixtures, it can be difficult for consumers to elucidate which
particular compounds are effective for stress reduction. Therefore,
there remains a need to identify fragrance accords that actually
impact an individual's reaction to stress. The present disclosure
addresses this need in further detail below.

DETAILED DESCRIPTION
[0037] As discussed above, there is a need in the art to determine
which fragrances and which accords within a fragrance impact a
subject's reaction to stress so as to formulate an effective
composition for treatment thereof. The presently disclosed subject
matter addresses this need through a fragrance composition
comprising at least one musk accord which can be administered to a
subject before, during, or after exposure to a stressor to
effectively reduce or inhibit stress.
1. Definitions
[0038] The terms used in this specification generally have their
ordinary meanings in the art, within the context of this disclosure
and in the specific context where each term is used. Certain terms
are discussed below, or elsewhere in the specification, to provide
additional guidance to the practitioner in describing the
compositions and methods of the disclosure and how to make and use
them.
[0039] As used herein, the use of the word "a" or "an" when used in
conjunction with the term "comprising" in the claims and/or the
specification may mean "one," but it is also consistent with the
meaning of "one or more," "at least one," and "one or more than
one." Still further, the terms "having," "including," "containing"
and "comprising" are interchangeable and one of skill in the art is
cognizant that these terms are open ended terms.
[0040] The term "about" or "approximately" means within an
acceptable error range for the particular value as determined by
one of ordinary skill in the art, which will depend in part on how
the value is measured or determined, i.e., the limitations of the
measurement system. For example, "about" can mean within 3 or more
than 3 standard deviations, per the practice in the art.
Alternatively, "about" can mean a range of up to 20%, preferably up
to 10%, more preferably up to 5%, and more preferably still up to
1% of a given value. Alternatively, particularly with respect to
biological systems or processes, the term can mean within an order
of magnitude, preferably within 5-fold, and more preferably within
2-fold, of a value.
[0041] As used herein, the term "fragrance sample" is taken to mean
any individual material, e.g., a fragrance composition (which is
synonymous with perfume ingredient and perfume material), which may
contain one or more musk or fragrance accords. It is also
understood that a "fragrance sample" can be a mixture of individual
materials, such as, for example, multiple accords or a fully
formulated fragrance. As used herein, the term "fragrance" may be
used interchangeably with the term "perfume".
[0042] As used herein, the term "accord" refers to a formulation
that contains one or more different musk compounds that create a
specific smell, odor or scent, and that causes a specific
physiological effect when used in proper effective amounts as
necessary.
[0043] As used herein, the term "stressor" and "stress stimuli" are
used interchangeably and refer to one of more event(s) which
induces a stress response in a subject. The stressor can be
chemical, biological, environmental, or another external stimulus
that causes a stress reaction within a subject's body.
[0044] As used herein, the term "subject" refers to a human or a
non-human subject. Non-limiting examples of non-human subjects
include non-human primates, dogs, cats, mice, rats, guinea pigs,
rabbits, pigs, fowl, horses, cows, goats, sheep, cetaceans,
etc.
[0045] As used herein, the term "treat" or "treating" refers to
intervention to alter (e.g., lower) the stress level of the
subject, e.g., by administering a fragrance composition.
[0046] As used herein, the term "reduce" refers to alter negatively
by at least about 5% including, but not limited to, alter
negatively by about 5%, by about 10%, by about 25%, by about 30%,
by about 50%, by about 75%, or by about 100%.
[0047] As used herein, the term "inhibit" or "prevent" refers to
the ability of compound or composition, e.g., a fragrance
composition, to stop, decrease, or reduce stress within a
subject.
[0048] As used herein, the term "enantiomers" refers to a pair of
stereoisomers that are non-superimposable mirror images of each
other. A 1:1 mixture of a pair of enantiomers is a "racemic"
mixture. The term is used to designate a racemic mixture where
appropriate.
[0049] As used herein, the term "diastereoisomers" refers to
stereoisomers that have at least two asymmetric atoms, but which
are not mirror-images of each other. The absolute stereochemistry
is specified according to the Cahn-Ingold-Prelog R--S system. When
a compound is a pure enantiomer the stereochemistry at each chiral
carbon may be specified by either R or S. Resolved compounds whose
absolute configuration is unknown can be designated (+) or (-)
depending on the direction (dextro or levorotatory) which they
rotate plane polarized light at the wavelength of the sodium D
line. The compounds of the presently disclosed subject matter
contain one or more asymmetric centers and may thus give rise to
enantiomers, diastereomers, and other stereoisomeric forms that may
be defined, in terms of absolute stereochemistry, as (R)- or (S)-.
The presently disclosed subject matter is meant to include all such
possible isomers, including racemic mixtures, optically pure forms
and intermediate mixtures. Optically active (R)- and (S)-isomers
may be prepared using chiral synthons or chiral reagents, or
resolved using conventional techniques. If the compound contains a
double bond, the substituent may be E or Z configuration. If the
compound contains a disubstituted cycloalkyl, the cycloalkyl
substituent may have a cis- or trans-configuration. All tautomeric
forms are also intended to be included.
[0050] As used herein, the term "isomers" refers to different
compounds that have the same molecular formula but differ in
arrangement and configuration of the atoms. Also as used herein,
the term "stereoisomer" refers to any of the various stereo
isomeric configurations which may exist for a given compound of the
presently disclosed subject matter and includes geometric isomers.
It is understood that a substituent may be attached at a chiral
center of a carbon atom. Therefore, the presently disclosed subject
matter includes enantiomers, diastereomers or racemates of the
compound. Also as used herein, the terms "constitutional isomers"
refers to different compounds which have the same numbers of, and
types of, atoms but the atoms are connected differently.
2. Musk Compounds
[0051] The fragrance compositions of the presently disclosed
subject matter comprise one or more musk compounds. Although
historically musk has been associated with an odorous substance
from a male musk deer gland, musk is now understood to encompass a
broad variety of compounds with similar odor characteristics. Musk
is a class of aromatic compounds structurally grouped for example
into polycyclic musks, macrocyclic musks, nitro musks, and acyclic
musks. Although structurally diverse, each musk compound gives an
odor, and the various compounds can be used alone or in
combination. Because of their pleasant odor character, musk
compounds have been incorporated into various product applications.
Surprisingly, despite these odor similarities, the subject
disclosure explains that it has been unexpectedly discovered that
within the classes of musk compounds, only certain compounds act on
the autonomic nervous system or the hypothalamus-pituitary-adrenal
(HPA) axis to effectively treat, reduce, inhibit or prevent stress
responses.
[0052] Musk fragrance compounds can include, but are not limited
to, 4-Cyclopentadecen-1-one, (4Z); 4-Cyclopentadecen-1-one;
9-Cycloheptadecen-1-one; 9-Cycloheptadecen-1-one, (9Z);
Oxacycloheptadecan-Z-one; .omega.-Hexadecanolide;
1,4-Dioxacyclohexadecane-5,16-dione; Oxacyclohexadecen-Z-one;
15-Pentadec-(11/12)-enolide; 1,4-Dioxacycloheptadecane-5,
17-dione;
[0053] 3-Methyl-cyclopentadecanone; Oxacycloheptadec-10-en-2-one;

[0072] In one embodiment, at least a fragrance composition
comprising one, two, three or more musk compounds can be added to a
consumer product, such as an air care product, to reduce the level
of stress in a subject using the product as compared to the level
of stress of a subject using a consumer product which does not
comprise the subject composition. For example, a composition
comprising two musk compounds may be added to a consumer product,
such as air freshener, which is utilized by a subject before
exposure to a stressor and effectively reduces the subject's
stress. In other embodiments, the product may be utilized by a
subject during or after exposure to a stressor, which effectively
reduces the subject's stress.
[0073] The concentration and/or amount of the fragrance composition
admixed with the consumer product to reduce or inhibit stress in a
consumer can change based on a number of variables, for example,
the specific consumer product, the physical form of the consumer
product (e.g., liquid, gas, or solid) and what fragrance compounds
are already present in the consumer product and the concentrations
and/or amounts thereof.
[0074] A broad range of concentrations and/or amounts of the

5. Reduction or Inhibition of Stress
[0104] In certain embodiments, the compositions of the presently
disclosed subject matter are administered in an amount effective to
reduce or inhibit stress in a subject.
5.1 Methods of Composition Administration
[0105] In certain embodiments of the present disclosure, the
composition comprising one or more musk compounds is administered
to a subject prior to, during, or after exposure to a stressor to
reduce or inhibit the subject's stress level.
[0106] In one non-limiting embodiment, the composition is
administered to a subject through gaseous or volatile form. In
these embodiments, the composition is administered intranasally or
by inhalation. In certain embodiments, the subject inhales the
composition directly or indirectly.
[0107] In further embodiments, the composition is administered via
a consumer product. In one non-limiting example, the composition is
admixed with a consumer product. The subject then uses the consumer
product comprising the composition. Depending on the use of the
consumer product, the subject is exposed to the fragrance
composition.
[0108] In a specific embodiment, the composition is released into
the area surrounding the subject and the subject then inhales the
composition. In one non-limiting example, the composition is
released into the air by a consumer product, such as an air
freshener.
[0109] In certain embodiments of the present disclosure, the amount
of the composition released from the consumer product is less than
the total concentration of the composition admixed with the
consumer product. In certain embodiments, the amount of the
composition released by the consumer product, and therefore
available for administration to the subject, is between about 1 and
100% of the amount of composition admixed with the consumer
product. In further embodiments, the amount of composition released
is between about 5 and 90%, between about 10 and 80%, between about
20 and 70%, between about 30 and 60%, and between about 40 and 50%
of the amount of composition admixed with the consumer product.
5.2 Methods of Measuring Stress Relief
[0110] In certain embodiments, the compositions of the presently
disclosed subject matter are administered in an amount effective to
reduce or inhibit stress in a subject as determined by measuring
the levels of specific hormones in a subject. In certain
embodiments, the composition is incorporated into a consumer
product, as discussed above, which is utilized by a subject before,
during, or after exposure to a stressor.
5.2.1 Biomarkers
[0111] In certain embodiments, the compositions of the presently
disclosed subject matter are administered to a subject, a stressor
is applied, and specific biomarkers are measured to determine the
level of stress reduction or inhibition.
[0112] In specific embodiments, the compositions of the presently
disclosed subject matter are effective at reducing or inhibiting
stress if a change in cortisol, or salivary amylase, or both are
detected.
5.2.1.1 Cortisol
[0113] Cortisol is released by the body as part of a longer term
response to stress, resulting from the activation of the
hypothalamus-pituitary-adrenal (HPA) axis. A change in cortisol
levels therefore indicates an subject's reaction, or lack therefor,
to a stressor.
[0114] Accordingly, in certain embodiments of the subject
disclosure, salivary cortisol levels are measured as biomarkers to
determine a subject's reaction, or lack thereof, to a stressor. A
reduction in, or maintenance of, the level of biomarker indicates
that the composition reduced or inhibited stress in a subject. In
certain embodiments, the subject's level of salivary cortisol is
measure before and after the application of a stressor. In certain
embodiments the salivary cortisol level is measured, the
composition is administered, the stressor is applied and then the
salivary cortisol level is measured again. The percent change in
the salivary cortisol level can then be calculated.
[0115] In certain embodiments, the composition is administered to a
subject in an amount effective to reduce or maintain the level of
salivary cortisol in the subject when the subject is exposed to a
stressor as compared to the level of salivary cortisol in the
subject before exposure to the stressor. In certain embodiments,
the reduction in the level of salivary cortisol is between about 1
and about 100%, or between about 2 and about 75%, or between about
5 and about 50%, or between about 10 and about 45%, or between
about 15 and about 40%, or between about 20 and about 35%, or
between about 25 and about 30%. In certain embodiments, the
reduction in the level of salivary cortisol is between about 1 and
about 50%, or between about 1 and about 40%, or between about 1 and
about 30%, or between about 1 and about 20%, or between about 1 and
about 10%, or between about 1 and about 5%.
5.2.1.2 Alpha-Amylase
[0116] Salivary alpha-amylase is a digestive enzyme produced in and
released from the saliva glands. Levels of salivary alpha-amylase
increase in response to psychological and physical stress through
interactions with the autonomic nervous system. Accordingly, in
certain embodiments of the subject disclosure, salivary
alpha-amylase levels are measured to determine an subject's
reaction, or lack thereof, to a stressor. A reduction in, or
maintenance of, the level of salivary alpha-amylase indicates that
the composition reduced or inhibited stress in a subject. In
certain embodiments, the subject's level of salivary alpha-amylase
is measured before and after the application of a stressor. In
certain embodiments the salivary alpha-amylase level is measured,
the composition is administered, the stressor is applied and then
the salivary alpha-amylase level is measured again. The percent
change in the salivary alpha-amylase level can then be
calculated.
[0117] In certain embodiments, the composition is administered to a
subject in an amount effective to reduce the level of salivary
alpha-amylase in the subject when the subject is exposed to a
stressor as compared to the level of salivary alpha-amylase in the
subject before, during, or after exposure to the stressor.
[0118] In certain embodiments, the reduction in the level of
salivary alpha-amylase is between about 15 and about 200%, or
between about 20 and about 180%, or between about 25 and about
160%, or between about 30 and about 140%, or between about 35 and
about 120%, or between about 40 and about 115%, or between about 45
and about 110%, or between about 50 and about 105%, or between
about 50 and about 100%, or between about 55 and about 95%, or
between about 60 and about 90%, or between about 65 and about 85%,
or between about 70 and about 80%.
[0119] In certain embodiments, the reduction in the level of
salivary alpha-amylase is at least about 2%, about 5%, about 7.5%,
about 10%, about 15%, or about 20%.
[0120] In certain embodiments, the reduction in the level of
salivary alpha-amylase is between about 2% and about 100%, or
between about 2% and about 75%, or between about 2% and about 50%,
or between about 2% and about 40%, or between about 2% and about
30%, or between about 2% and about 20%, or between about 5% and
about 20%.
6. Fragrance Delivery Systems
[0121] The benefits of the musks disclosed herein may be further
enhanced by employing a delivery system to apply such musks.
Non-limiting examples of suitable delivery systems, methods of
making delivery systems and the uses of such delivery systems are
disclosed in .S. Patent publication no. 2007/0275866 A1. Such
delivery systems include the following.
[0122] Polymer Assisted Delivery (PAD): This fragrance delivery
technology uses polymeric materials to deliver fragrance materials.
Classical coacervation, water soluble or partly soluble to
insoluble charged or neutral polymers, liquid crystals, hot melts,
hydrogels, fragranced plastics, microcapsules, nano- and
micro-latexes, polymeric film formers, and polymeric absorbents,
polymeric adsorbents, etc. are some examples. PAD includes but is
not limited to:
[0123] Matrix Systems: The fragrance is dissolved or dispersed in a
polymer matrix or particle. Fragrances, for example, may be 1)
dispersed into the polymer prior to formulating into the product or
2) added separately from the polymer during or after formulation of
the product. Diffusion of fragrance from the polymer is a common
trigger that allows or increases the rate of fragrance release from
a polymeric matrix system that is deposited or applied to the
desired surface (situs), although many other triggers are known
that may control fragrance release. Absorption and/or adsorption
into or onto polymeric particles, films, solutions, and the like
are aspects of this technology. Nano- or micro-particles composed
of organic materials (e.g., latexes) are examples. Suitable
particles include a wide range of materials including, but not
limited to polyacetal, polyacrylate, polyacrylic,
polyacrylonitrile, polyamide, polyaryletherketone, polybutadiene,
polybutylene, polybutylene terephthalate, polychloroprene,
polyethylene, polyethylene terephthalate, polycyclohexylene
dimethylene terephthalate, polycarbonate, polychloroprene,
polyhydroxyalkanoate, polyketone, polyester, polyetherimide,
polyethersulfone, polyethylenechlorinates, polyimide, polyisoprene,
polylactic acid, polymethylpentene, polyphenylene oxide,
polyphenylene sulfide, polyphthalamide, polypropylene, polystyrene,
polysulfone, polyvinyl acetate, polyvinyl chloride, as well as
polymers or copolymers based on acrylonitrile-butadiene, cellulose
acetate, ethylene-vinyl acetate, ethylene vinyl alcohol,
styrene-butadiene, vinyl acetate-ethylene, and mixtures
thereof.
[0124] "Standard" systems refer to those that are "pre-loaded" with
the intent of keeping the pre-loaded fragrance associated with the
polymer until the moment or moments of fragrance release.
[0125] Such polymers may also suppress the neat product odor and
provide a bloom and/or longevity benefit depending on the rate of
fragrance release. One challenge with such systems is to achieve
the ideal balance between 1) in-product stability (keeping
fragrance inside carrier until you need it) and 2) timely release
(during use or from dry situs). Achieving such stability is
particularly important during in-product storage and product aging.
This challenge is particularly apparent for aqueous-based,
surfactant-containing products, such as heavy duty liquid laundry
detergents. Many "Standard" matrix systems available effectively
become "Equilibrium" systems when formulated into aqueous-based
products. One may select an "Equilibrium" system or a Reservoir
system, which has acceptable in-product diffusion stability and
available triggers for release (e.g., friction). "Equilibrium"
systems are those in which the fragrance and polymer may be added
separately to the product, and the equilibrium interaction between
fragrance and polymer leads to a benefit at one or more consumer
touch points (versus a free fragrance control that has no
polymer-assisted delivery technology). The polymer may also be
pre-loaded with fragrance; however, part or all of the fragrance
may diffuse during in-product storage reaching an equilibrium that
includes having desired perfume raw materials (PRMs) associated
with the polymer. The polymer then carries the fragrance to the
surface, and releases it typically via fragrance diffusion. The use
of such equilibrium system polymers has the potential to decrease
the odor intensity of the neat product (usually more so in the case
of pre-loaded standard systems). Deposition of such polymers may
serve to "flatten" the release profile and provide increased
longevity. As indicated above, such longevity would be achieved by
suppressing the initial intensity and may enable the formulator to
use more high impact or low odor detection threshold (ODT) or low
Kovats Index (KI) PRMs to achieve FMOT benefits without initial
intensity that is too strong or distorted. It is important that
fragrance release occurs within the time frame of the application
to impact the desired consumer touch point or touch points. Matrix
systems also include hot melt adhesives and fragrance plastics. In
addition, hydrophobically modified polysaccharides may be
formulated into the fragranced product to increase fragrance
deposition and/or modify fragrance release. All such matrix
systems, including for example polysaccharides and nanolatexes may
be combined with other PDTs, including other PAD systems such as
PAD reservoir systems in the form of a perfume microcapsule
(PMC).
[0126] Silicones are also examples of polymers that may be used as
PDT, and can provide fragrance benefits in a manner similar to the
polymer-assisted delivery "matrix system". Such a PDT is referred
to as silicone-assisted delivery (SAD). One may pre-load silicones
with fragrance, or use them as an equilibrium system as described
for PAD. Examples of silicones include polydimethylsiloxane and
polyalkyldimethylsiloxanes. Other examples include those with amine
functionality, which may be used to provide benefits associated
with amine-assisted delivery (AAD) and/or polymer-assisted delivery
(PAD) and/or amine-reaction products (ARP).
[0127] Reservoir Systems: Reservoir systems are also known as a
core-shell type technology, or one in which the fragrance is
surrounded by a fragrance release controlling membrane, which may
serve as a protective shell. The material inside the microcapsule
is referred to as the core, internal phase, or fill, whereas the
wall is sometimes called a shell, coating, or membrane.
Microparticles or pressure sensitive capsules or microcapsules are
examples of this technology. Microcapsules of the current invention
are formed by a variety of procedures that include, but are not
limited to, coating, extrusion, spray-drying, interfacial, in-situ
and matrix polymerization. The possible shell materials vary widely
in their stability toward water. Among the most stable are
polyoxymethyleneurea (PMU)-based materials, which may hold certain
PRMs for even long periods of time in aqueous solution (or
product). Such systems include but are not limited to
urea-formaldehyde and/or melamine-formaldehyde. Gelatin-based
microcapsules may be prepared so that they dissolve quickly or
slowly in water, depending for example on the degree of
cross-linking. Many other capsule wall materials are available and
vary in the degree of fragrance diffusion stability observed.
Without wishing to be bound by theory, the rate of release of
fragrance from a capsule, for example, once deposited on a surface
is typically in reverse order of in-product fragrance diffusion
stability. As such, urea-formaldehyde and melamine-formaldehyde
microcapsules for example, typically require a release mechanism
other than, or in addition to, diffusion for release, such as
mechanical force (e.g., friction, pressure, shear stress) that
serves to break the capsule and increase the rate of perfume
(fragrance) release. Other triggers include melting, dissolution,
hydrolysis or other chemical reaction, electromagnetic radiation,
and the like. The use of pre-loaded microcapsules requires the
proper ratio of in-product stability and in-use and/or on-surface
(on-situs) release, as well as proper selection of PRMs.
Microcapsules that are based on urea-formaldehyde and/or
melamine-formaldehyde are relatively stable, especially in near
neutral aqueous-based solutions. These materials may require a
friction trigger which may not be applicable to all product
applications. Other microcapsule materials (e.g., gelatin) may be
unstable in aqueous-based products and may even provide reduced
benefit (versus free perfume control) when in-product aged. Scratch
and sniff technologies are yet another example of PAD.
[0128] Molecule-Assisted Delivery (MAD): Non-polymer materials or
molecules may also serve to improve the delivery of fragrance.
Without wishing to be bound by theory, fragrance may non-covalently
interact with organic materials, resulting in altered deposition
and/or release. Non-limiting examples of such organic materials
include but are not limited to hydrophobic materials such as
organic oils, waxes, mineral oils, petrolatum, fatty acids or
esters, sugars, surfactants, liposomes and even other fragrance raw
material (perfume oils), as well as natural oils, including body
and/or other soils. Perfume fixatives are yet another example. In
one aspect, non-polymeric materials or molecules have a CLogP
greater than about 2.
[0129] Cyclodextrin (CD): This technology approach uses a cyclic
oligosaccharide or cyclodextrin to improve the delivery of
fragrance. Typically a fragrance and cyclodextrin (CD) complex is
formed. Such complexes may be preformed, formed in-situ, or formed
on or in the situs. Without wishing to be bound by theory, loss of
water may serve to shift the equilibrium toward the CD-Fragrance
complex, especially if other adjunct ingredients (e.g., surfactant)
are not present at high concentration to compete with the fragrance
for the cyclodextrin cavity. A bloom benefit may be achieved if
water exposure or an increase in moisture content occurs at a later
time point. In addition, cyclodextrin allows the fragrance
formulator increased flexibility in selection of PRMs. Cyclodextrin
may be pre-loaded with fragrance or added separately from fragrance
to obtain the desired fragrance stability, deposition or release
benefit.
[0130] Starch Encapsulated Accord (SEA): The use of a starch
encapsulated accord (SEA) technology allows one to modify the
properties of the fragrance, for example, by converting a liquid
fragrance into a solid by adding ingredients such as starch. The
benefit includes increased fragrance retention during product
storage, especially under non-aqueous conditions. Upon exposure to
moisture, a fragrance bloom may be triggered. Benefits at other
moments of truth may also be achieved because the starch allows the
product formulator to select PRMs or PRM concentrations that
normally cannot be used without the presence of SEA. Another
technology example includes the use of other organic and inorganic
materials, such as silica to convert fragrance from liquid to
solid.
[0131] Zeolite & Inorganic Carrier (ZIC): This technology
relates to the use of porous zeolites or other inorganic materials
to deliver fragrances. Perfume-loaded zeolite may be used with or
without adjunct ingredients used for example to coat the
perfume-loaded zeolite (PLZ) to change its perfume release
properties during product storage or during use or from the dry
situs. Silica is another form of ZIC. Another example of a suitable
inorganic carrier includes inorganic tubules, where the perfume or
other active material is contained within the lumen of the nano- or
micro-tubules. Preferably, the perfume-loaded inorganic tubule (or
Perfume-Loaded Tubule or PLT) is a mineral nano- or micro-tubule,
such as halloysite or mixtures of halloysite with other inorganic
materials, including other clays. The PLT technology may also
comprise additional ingredients on the inside and/or outside of the
tubule for the purpose of improving in-product diffusion stability,
deposition on the desired situs or for controlling the release rate
of the loaded fragrance. Monomeric and/or polymeric materials,
including starch encapsulation, may be used to coat, plug, cap, or
otherwise encapsulate the PLT.

ethylenediaminetetra (methyl-enephosphonic acid) and water-soluble
salts thereof.
[0151] If desired, the compositions herein can be catalyzed by
means of a manganese compound. Such compounds and levels of use are
well known in the art.
[0152] Compositions herein may also suitably include a transition
metal complex of a macropolycyclic rigid ligand--abbreviated as
"MRL". As a practical matter, and not by way of limitation, the
compositions and cleaning processes herein can be adjusted to
provide on the order of at least one part per hundred million of
the benefit agent MRL species in the aqueous washing medium, and
may provide from about 0.005 ppm to about 25 ppm, from about 0.05
ppm to about 10 ppm, or even from about 0.1 ppm to about 5 ppm, of
the MRL in the wash liquor.
[0153] Preferred transition-metals in the instant transition-metal
bleach catalyst include manganese, iron and chromium. Preferred
MRL's herein are a special type of ultra-rigid ligand that is
cross-bridged such as
5,12-diethyl-1,5,8,12-tetraazabicyclo[6.6.2]hexa-decane.
[0154] Rheology Modifier. The liquid compositions of the present
invention may comprise a rheology modifier. The rheology modifier
may be selected from the group consisting of non-polymeric
crystalline, hydroxy-functional materials, polymeric rheology
modifiers which impart shear thinning characteristics to the
aqueous liquid matrix of the composition. In one aspect, such
rheology modifiers impart to the aqueous liquid composition a high
shear viscosity, at 20 sec-1 shear rate and at 21.degree. C., of
from 1 to 7000 cps and a viscosity at low shear (0.5 sec-1 shear
rate at 21.degree. C.) of greater than 1000 cps, or even 1000 cps
to 200,000 cps. In one aspect, for cleaning and treatment
compositions, such rheology modifiers impart to the aqueous liquid
composition a high shear viscosity, at 20 sec-1 and at 21.degree.
C., of from 50 to 3000 cps and a viscosity at low shear (0.5 sec-1
shear rate at 21.degree. C.) of greater than 1000 cps, or even 1000
cps to 200,000 cps. Viscosity according to the present invention is
measured using an AR 2000 rheometer from TA instruments using a
plate steel spindle having a plate diameter of 40 mm and a gap size
of 500 .mu.m. The high shear viscosity at 20 sec-1 and low shear
viscosity at 0.5sec-1 can be obtained from a logarithmic shear rate
sweep from 0.1 sec-1 to 25 sec-1 in 3 minutes time at 21.degree. C.
Crystalline hydroxyl functional materials are rheology modifiers
which form thread-like structuring systems throughout the matrix of
the composition upon in situ crystallization in the matrix.
Polymeric rheology modifiers are preferably selected from
polyacrylates, polymeric gums, other non-gum polysaccharides, and
combinations of these polymeric materials.
[0155] Generally the rheology modifier will comprise from 0.01% to
1% by weight, preferably from 0.05% to 0.75% by weight, more
preferably from 0.1% to 0.5% by weight, of the compositions
herein.
[0156] Structuring agents which are especially useful in the
compositions of the present invention may comprise non-polymeric
(except for conventional alkoxylation), crystalline
hydroxy-functional materials which can form thread-like structuring
systems throughout the liquid matrix when they are crystallized
within the matrix in situ. Such materials can be generally
characterized as crystalline, hydroxyl-containing fatty acids,
fatty esters or fatty waxes. In one aspect, rheology modifiers
include crystalline, hydroxyl-containing rheology modifiers include
castor oil and its derivatives. In one aspect, rheology modifiers
include hydrogenated castor oil derivatives such as hydrogenated
castor oil and hydrogenated castor wax. Commercially available,
castor oil-based, crystalline, hydroxyl-containing rheology
modifiers include THIXCIN.TM. from Rheox, Inc. (now Elementis).
[0157] Other types of rheology modifiers, besides the
non-polymeric, crystalline, hydroxyl-containing rheology modifiers
described heretofore, may be utilized in the liquid detergent
compositions herein. Polymeric materials which provide
shear-thinning characteristics to the aqueous liquid matrix may
also be employed.
[0158] Suitable polymeric rheology modifiers include those of the
polyacrylate, polysaccharide or polysaccharide derivative type.
Polysaccharide derivatives typically used as rheology modifiers
comprise polymeric gum materials. Such gums include pectine,
alginate, arabinogalactan (gum Arabic), carrageenan, gellan gum,
xanthan gum and guar gum.
[0159] If polymeric rheology modifiers are employed herein, a
preferred material of this type is gellan gum. Gellan gum is a
heteropolysaccharide prepared by fermentation of Pseudomonaselodea
ATCC 31461. Gellan gum is commercially marketed by CP Kelco U.S.,
Inc. under the KELCOGEL tradename.
[0160] A further alternative and suitable rheology modifier include
a combination of a solvent and a polycarboxylate polymer. More
specifically the solvent may be an alkylene glycol. In one aspect,
the solvent may comprise dipropylene glycol. In one aspect, the
polycarboxylate polymer may comprise a polyacrylate,
polymethacrylate or mixtures thereof. In one aspect, solvent may be
present, based on total composition weight, at a level of from 0.5%
to 15%, or from 2% to 9% of the composition. In one aspect,
polycarboxylate polymer may be present, based on total composition
weight, at a level of from 0.1% to 10%, or from 2% to 5%. In one
aspect, the solvent component may comprise mixture of dipropylene
glycol and 1,2-propanediol. In one aspect, the ratio of dipropylene
glycol to 1,2-propanediol may be 3:1 to 1:3, or even 1:1. In one
aspect, the polyacrylate may comprise a copolymer of unsaturated
mono- or di-carbonic acid and C.sub.1-C.sub.30 alkyl ester of the
(meth) acrylic acid. In another aspect, the rheology modifier may
comprise a polyacrylate of unsaturated mono- or di-carbonic acid
and C.sub.1-C.sub.30 alkyl ester of the (meth) acrylic acid. Such
copolymers are available from Noveon Inc. under the tradename
Carbopol Aqua 30.RTM..
[0161] In the absence of rheology modifier and in order to impart
the desired shear thinning characteristics to the liquid
composition, the liquid composition can be internally structured
through surfactant phase chemistry or gel phases.

7.2 Antiperspirant Compositions
[0175] Antiperspirant compositions can be formulated in many forms.
For example an antiperspirant composition can be, without
limitation, a roll on product, a body spray, a stick including soft
solid sticks and invisible solids, or an aerosol. Each of the
antiperspirant compositions described below can include fragrance
materials as described herein.
7.2.1 Roll-On and Clear Gel
[0176] A roll-on antiperspirant composition can comprise, for
example, water, emollient, solubilizer, deodorant actives,
antioxidants, preservatives, or combinations thereof. A clear gel
antiperspirant composition can comprise, for example, water,
emollient, solubilizer, deodorant actives, antioxidants,

[0177] Water. The roll-on composition can include water. Water can
be present in an amount of about 1% to about 99.5%, about 25% to
about 99.5%, about 50% to about 99.5%, about 75% to about 99.5%
about 80% to about 99.5%, from about 15% to about 45%, or any
combination of the end points and points encompassed within the
ranges, by weight of the deodorant composition.
[0178] Emollients. Roll-on compositions can comprise an emollient
system including at least one emollient, but it could also be a
combination of emollients. Suitable emollients are often liquid
under ambient conditions. Depending on the type of product form
desired, concentrations of the emollient(s) in the deodorant
compositions can range from about 1% to about 95%, from about 5% to
about 95%, from about 15% to about 75%, from about 1% to about 10%,
from about 15% to about 45%, or from about 1% to about 30%, by
weight of the deodorant composition.
[0179] Emollients suitable for use in the roll-on compositions
include, but are not limited to, propylene glycol, polypropylene
glycol (like dipropylene glycol, tripropylene glycol, etc.),

[0180] Deodorant Actives. Suitable deodorant actives can include
any topical material that is known or otherwise effective in
preventing or eliminating malodor associated with perspiration.
Suitable deodorant actives may be selected from the group
consisting of antimicrobial agents (e.g., bacteriocides,
fungicides), malodor-absorbing material, and combinations thereof.
For example, antimicrobial agents may comprise
cetyl-trimethylammonium bromide, cetyl pyridinium chloride,
benzethonium chloride, diisobutyl phenoxy ethoxy ethyl dimethyl
benzyl ammonium chloride, sodium N-lauryl sarcosine, sodium
N-palmethyl sarcosine, lauroyl sarcosine, N-myristoyl glycine,

aluminum chlorohydroxy lactate, triethyl citrate, tricetylmethyl
ammonium chloride, 2,4,4'-trichloro-2'-hydroxy diphenyl ether
(triclosan), 3,4,4'-trichlorocarbanilide (triclocarban),

salts of citrate, salicylate, and piroctose, especially zinc salts,
and acids thereof, heavy metal salts of pyrithione, especially zinc
pyrithione, zinc phenolsulfate, farnesol, and combinations thereof.
The concentration of the optional deodorant active may range from
about 0.001%, from about 0.01%, of from about 0.1%, by weight of
the composition to about 20%, to about 10%, to about 5%, or to
about 1%, by weight of the composition.
[0181] Odor Entrappers. The composition can include an odor
entrapper. Suitable odor entrappers for use herein include, for
example, solubilized, water-soluble, uncomplexed cyclodextrin. As
used herein, the term "cyclodextrin" includes any of the known
cyclodextrins such as unsubstituted cyclodextrins containing from
six to twelve glucose units, especially, alpha-cyclodextrin,
beta-cyclodextrin, gamma-cyclodextrin and/or their derivatives
and/or mixtures thereof. The alpha-cyclodextrin consists of six
glucose units, the beta-cyclodextrin consists of seven glucose
units, and the gamma-cyclodextrin consists of eight glucose units
arranged in a donut-shaped ring. The specific coupling and
conformation of the glucose units give the cyclodextrins a rigid,
conical molecular structure with a hollow interior of a specific
volume. The "lining" of the internal cavity is formed by hydrogen
atoms and glycosidic bridging oxygen atoms, therefore this surface
is fairly hydrophobic. The unique shape and physical-chemical
property of the cavity enable the cyclodextrin molecules to absorb
(form inclusion complexes with) organic molecules or parts of
organic molecules which can fit into the cavity. Many fragrance
molecules can fit into the cavity.
[0182] Cyclodextrin molecules are described in U.S. Pat. Nos.
5,714,137, and 5,942,217. Suitable levels of cyclodextrin are from
about 0.1% to about 5%, alternatively from about 0.2% to about 4%,
alternatively from about 0.3% to about 3%, alternatively from about
0.4% to about 2%, by weight of the composition.
[0183] Buffering Agent. The composition can include a buffering
agent which may be alkaline, acidic or neutral. The buffer can be
used in the composition for maintaining the desired pH. The
composition may have a pH from about 3 to about 10, from about 4 to
about 9, from about 5 to about 8, from about 6 to about 7, or it
may have a pH of about 6.5. One unique feature of the polyvinyl
amine malodor control polymers is its ability to maintain active
nitrogen sites at high pH levels which can help enhance the
antibacterial effect which comes, at least in part, from the
nitrogen sites.
[0184] Suitable buffering agents include, for example, hydrochloric
acid, sodium hydroxide, potassium hydroxide, and combinations
thereof.
[0185] The compositions can contain at least about 0%,
alternatively at least about 0.001%, alternatively at least about
0.01%, by weight of the composition, of a buffering agent. The
composition may also contain no more than about 1%, alternatively
no more than about 0.75%, alternatively no more than about 0.5%, by
weight of the composition, of a buffering agent.
[0186] Solubilizer. The composition can contain a solubilizer. A
suitable solubilizer can be, for example, a surfactant, such as a
no-foaming or low-foaming surfactant. Suitable surfactants are
nonionic surfactants, cationic surfactants, amphoteric surfactants,
zwitterionic surfactants, and mixtures thereof.
[0187] Suitable solubilizers include, for example, hydrogenated
castor oil, polyoxyethylene 2 stearyl ether, polyoxyethylene 20
stearyl ether, and combinations thereof. One suitable hydrogenated
castor oil that may be used in the present composition is
polyoxyethylene hydrogenated castor oil.
[0188] When the solubilizing agent is present, it is typically
present at a level of from about 0.01% to about 5%, alternatively
from about 0.01% to about 3%, alternatively from about 0.05% to
about 1%, alternatively from about 0.01% to about 0.05%, by weight
of the composition.
[0189] Preservatives. The composition can include a preservative.
The preservative is included in an amount sufficient to prevent
spoilage or prevent growth of inadvertently added microorganisms
for a specific period of time, but not sufficient enough to
contribute to the odor neutralizing performance of the composition.
In other words, the preservative is not being used as the
antimicrobial compound to kill microorganisms on the surface onto
which the composition is deposited in order to eliminate odors
produced by microorganisms. Instead, it is being used to prevent
spoilage of the composition in order to increase shelf-life.
[0190] The preservative can be any organic preservative material
which will not cause damage to fabric appearance, e.g.,
discoloration, coloration, bleaching. Suitable water-soluble
preservatives include organic sulfur compounds, halogenated
compounds, cyclic organic nitrogen compounds, low molecular weight
aldehydes, parabens, propane diol materials, isothiazolinones,
quaternary compounds, benzoates, low molecular weight alcohols,
dehydroacetic acid, phenyl and phenoxy compounds, or mixtures
thereof.

about 750 gramforce to about 2,000 gramforce, and yet more
specifically from about 800 gramforce to about 1,400 gramforce.
[0198] The term "product hardness" or "hardness" as used herein is
a reflection of how much force is required to move a penetration
cone a specified distance and at a controlled rate into an
antiperspirant composition under the test conditions described
herein below. Higher values represent harder product, and lower
values represent softer product. These values are measured at
27.degree. C., 15% relative humidity, using a TA-XT2 Texture
Analyzer, available from Texture Technology Corp., Scarsdale, N.Y.,
U.S.A. The product hardness value as used herein represents the
peak force required to move a standard 45-degree angle penetration
cone through the composition for a distance of 10 mm at a speed of
2 mm/second. The standard cone is available from Texture Technology
Corp., as part number TA-15, and has a total cone length of about
24.7 mm, angled cone length of about 18.3 mm, and a maximum
diameter of the angled surface of the cone of about 15.5 mm. The
cone is a smooth, stainless steel construction and weighs about
17.8 grams.
[0199] Primary Structurants. The invisible solid can comprise a
suitable concentration of a primary structurant to help provide the
antiperspirant with the desired viscosity, rheology, texture and/or
product hardness, or to otherwise help suspend any dispersed solids
or liquids within the composition.
[0200] The term "solid structurant" as used herein means any
material known or otherwise effective in providing suspending,
gelling, viscosifying, solidifying, and/or thickening properties to
the composition or which otherwise provide structure to the final
product form. These solid structurants include gelling agents, and
polymeric or non-polymeric or inorganic thickening or viscosifying
agents. Such materials will typically be solids under ambient
conditions and include organic solids, crystalline or other
gellants, inorganic particulates such as clays or silicas, or
combinations thereof.
[0201] The concentration and type of solid structurant selected for
use in the antiperspirant compositions will vary depending upon the
desired product hardness, rheology, and/or other related product
characteristics. For most structurants suitable for use herein, the
total structurant concentration ranges from about 5% to about 35%,
more typically from about 10% to about 30%, or from about 7% to
about 20%, by weight of the composition.
[0202] Non-limiting examples of suitable primary structurants
include stearyl alcohol and other fatty alcohols; hydrogenated
castor wax (e.g., Castorwax MP80, Castor Wax, etc.); hydrocarbon
waxes include paraffin wax, beeswax, carnauba, candelilla,

[0204] Antiperspirant Active. The antiperspirant stick compositions
can comprise a particulate antiperspirant active suitable for
application to human skin. The concentration of antiperspirant
active in the composition should be sufficient to provide the
desired perspiration wetness and odor control from the
antiperspirant stick formulation selected.
[0205] The antiperspirant stick compositions can comprise an
antiperspirant active at concentrations of from about 0.5% to about
60%, and more specifically from about 5% to about 35%, by weight of
the composition. These weight percentages are calculated on an
anhydrous metal salt basis exclusive of water and any complexing
agents such as, for example, glycine, and glycine salts. The
antiperspirant active as formulated in the composition can be in
the form of dispersed particulate solids having an average particle
size or equivalent diameter of less than about 100 microns, more
specifically less than about 20 microns, and even more specifically
less than about 10 microns.
[0206] The antiperspirant active for use in the anhydrous
antiperspirant compositions of the present invention can include
any compound, composition or other material having antiperspirant
activity. More specifically, the antiperspirant actives may include
astringent metallic salts, especially inorganic and organic salts
of aluminum, zirconium and zinc, as well as mixtures thereof. Even
more specifically, the antiperspirant actives may include
aluminum-containing and/or zirconium-containing salts or materials,
such as, for example, aluminum halides, aluminum chlorohydrate,
aluminum hydroxyhalides, zirconyl oxyhalides, zirconyl
hydroxyhalides, and mixtures thereof.
[0207] Aluminum salts for use in the anhydrous antiperspirant stick
compositions include those that conform to the formula:
Al.sub.2(OH).sub.aCl.sub.b.xH.sub.2O,
[0208] wherein a is from about 2 to about 5;
[0209] the sum of a and b is about 6;
[0210] x is from about 1 to about 6; and
[0211] a, b, and x may have non-integer values.
[0212] More specifically, aluminum chlorohydroxides referred to as
"5/6 basic chlorohydroxide" can be used, wherein a=5, and "2/3
basic chlorohydroxide", wherein a=4.
[0213] Processes for preparing aluminum salts are disclosed in U.S.
Pat. Nos. 3,887,692; 3,904,741; 4,359,456; and British Patent
Specification 2,048,229, the disclosures of which are incorporated
herein by reference for the purpose of describing processes for
preparing aluminum salts.
[0214] Mixtures of aluminum salts are described in British Patent
Specification 1,347,950, which description is also incorporated
herein by reference.
[0215] Zirconium salts for use in the anhydrous antiperspirant
stick compositions include those which conform to the formula:
ZrO(OH).sub.2-aCl.sub.a.xH.sub.2O,
[0216] wherein a is from about 1.5 to about 1.87;
[0217] x is from about 1 to about 7; and
[0218] a and x may both have non-integer values.
[0219] These zirconium salts are described in Belgian Patent
825,146, Schmitz, issued Aug. 4, 1975, which description is
incorporated herein by reference. Zirconium salts that additionally
contain aluminum and glycine, commonly known as "ZAG complexes,"
are believed to be especially beneficial. These ZAG complexes
contain aluminum chlorohydroxide and zirconyl hydroxy chloride
conforming to the above-described formulas. Such ZAG complexes are
described in U.S. Pat. No. 3,792,068; Great Britain Patent
Application 2,144,992; and U.S. Pat. No. 4,120,948, disclosures of
which are incorporated herein by reference for the limited purpose
of describing ZAG complexes.
[0220] Also suitable for use herein are enhanced efficacy
aluminum-zirconium chlorohydrex-amino acid which typically has the
empirical formula
AlnZr(OH).sub.[3n+4-m(n+1)](Cl.sub.[m(n+1)]-AA.sub.q where n is 2.0
to 10.0, preferably 3.0 to 8.0; m is about 0.48 to about 1.11
(which corresponds to M:Cl approximately equal to 2.1-0.9),
preferably about 0.56 to about 0.83 (which corresponds to M:Cl
approximately equal to 1.8-1.2); q is about 0.8 to about 4.0,
preferably about 1.0 to 2.0; and AA is an amino acid such as
glycine, alanine, valine, serine, leucine, isoleucine,
.beta.-alanine, cysteine, .beta.-amino-n-butyric acid, or
.gamma.-amino-n-butyric acid, preferably glycine. These salts also
generally have some water of hydration associated with them,
typically on the order of 1 to 5 moles per mole of salt (typically,
about 1% to about 16%, more typically about 4% to about 13% by
weight). These salts are generally referred to as
aluminum-zirconium trichlorohydrex or tetrachlorohydrex when the
Al:Zr ratio is between 2 and 6 and as aluminum-zirconium
pentachlorohydrex or octachlorohydrex when the Al:Zr ratio is
between 6 and 10. The term "aluminum-zirconium chlorohydrex" is
intended to embrace all of these forms. The preferred
aluminum-zirconium salt is aluminum-zirconium chlorohydrex-glycine.
Additional examples of suitable high efficacy antiperspirant
actives can include Aluminum Zirconium Pentachlorohydrex Glycine,
Aluminum Zirconium Octachlorohydrex Glycine, or a combination
thereof. These high efficacy actives are more fully described in
U.S. App. Pub. No.

7.2.4 Additional Chassis Ingredients
[0222] Additional Structurant. The antiperspirant composition can
further comprise an additional structurant. The additional
structurant may be present in an amount from 1% to about 10%, by

and 5,891,424.
[0225] Solvent. The antiperspirant composition can comprise a
solvent at concentrations ranging from about 20% to about 80%, and
more specifically from about 30% to about 70%, by weight of the
composition. The solvent can be a volatile silicone which may be
cyclic or linear.
[0226] "Volatile silicone" as used herein refers to those silicone
materials that have measurable vapor pressure under ambient
conditions. Non-limiting examples of suitable volatile silicones
are described in Todd et al., "Volatile Silicone Fluids for
Cosmetics", Cosmetics and Toiletries, 91:27-32 (1976), which
descriptions are incorporated herein by reference.
[0227] The volatile silicone can be a cyclic silicone having from 3
to 7, and more specifically from 5 to 6, silicon atoms, and still
more specifically 5, like cyclopentasiloxane. These cyclic silicone
materials will generally have viscosities of less than about 10
centistokes at 25.degree. C.
[0228] Linear volatile silicone materials suitable for use in the
antiperspirant compositions include those represented by the
formula:
##STR00001##
[0229] wherein n is from 1 to 7, and more specifically from 2 to 3.
These linear silicone materials will generally have viscosities of
less than about 5 centistokes at 25.degree. C.
[0230] Specific examples of volatile silicone solvents suitable for
use in the antiperspirant compositions include, but are not limited
to, Cyclomethicone D-5; GE 7207 and GE 7158 (commercially available
from General Electric Co.); Dow Corning 344; Dow Corning 345; Dow
Corning 200; and DC1184 (commercially available from Dow Corning
Corp.); and SWS-03314 (commercially available from SWS
Silicones).
[0231] Non-Volatile Organic Fluids. Non-volatile organic fluids may
be present, for example, in an amount of about 15% or less, by
weight of the composition.
[0232] Non-limiting examples of nonvolatile organic fluids include
mineral oil, PPG-14 butyl ether, isopropyl myristate, petrolatum,
butyl stearate, cetyl octanoate, butyl myristate, myristyl
myristate, C12-15 alkylbenzoate (e.g., Finsolv.TM.),
octyldodecanol, isostearyl isostearate, octododecyl benzoate,
isostearyl lactate, isostearyl palmitate, and isobutyl
stearate.
[0233] Adjunct Ingredients. The anhydrous antiperspirant
compositions can further comprise any optional material that is
known for use in antiperspirant and deodorant compositions or other
personal care products, or which is otherwise suitable for topical
application to human skin.
[0234] One example of optional materials are clay mineral powders
such as talc, mica, sericite, silica, magnesium silicate, synthetic
fluorphlogopite, calcium silicate, aluminum silicate, bentonite and
montomorillonite; pearl pigments such as alumina, barium sulfate,
calcium secondary phosphate, calcium carbonate, titanium oxide,

and combinations thereof.
[0235] Talc, if used at higher levels can produce a significant
amount of white residue which has been found to be a consumer
negative for product acceptance. Therefore it is best to limit the
composition to less than 10%, less than about 8%, less than about
6%, or less than about 3%, by weight of the composition.
[0236] Nonlimiting examples of other optional materials include
emulsifiers, distributing agents, antimicrobials, pharmaceutical or
other topical active, preservatives, surfactants, and so forth.
Examples of such optional materials are described in U.S. Pat. Nos.
4,049,792; 5,019,375; and 5,429,816; which descriptions are
incorporated herein by reference.
7.2.5 Soft Solid
[0237] Soft solid composition can comprise volatile silicone,
antiperspirant active, gellant, residue masking material, or
combinations thereof. In addition, soft solids generally have a
hardness value after dispensing of about 500 gram force or
less.
[0238] Volatile Silicone Solvent. The soft solid can comprises a
volatile silicone solvent at concentrations ranging from about 20%
to about 80%, preferably from about 30% to about 70%, more
preferably from about 45% to about 70%, by weight of the
composition. The volatile silicone of the solvent may be cyclic or
linear.
[0239] "Volatile silicone" as used herein refers to those silicone
materials which have measurable vapor pressure under ambient
conditions. Nonlimiting examples of suitable volatile silicones are
described in Todd et al., "Volatile Silicone Fluids for Cosmetics",
Cosmetics and Toiletries, 91:27-32 (1976), which descriptions are
incorporated herein by reference. Preferred volatile silicone
materials are those having from about 3 to about 7, preferably from
about 4 to about 5, silicon atoms.
[0240] Cyclic volatile silicones are preferred for use in the
antiperspirant compositions herein, and include those represented
by the formula:
##STR00002##
[0241] wherein n is from about 3 to about 7, preferably from about
4 to about 5, most preferably 5. These cyclic silicone materials
will generally have viscosities of less than about 10 centistokes
at 25.degree. C.
[0242] Linear volatile silicone materials suitable for use in the
antiperspirant compositions include those represented by the
formula:
##STR00003##
[0243] wherein n is from about 1 to about 7, preferably from about
2 to about 3. These linear silicone materials will generally have
viscosities of less than about 5 centistokes at 25.degree. C.
[0244] Specific examples of volatile silicone solvents suitable for
use in the antiperspirant compositions include, but are not limited
to, Cyclomethicone D-5 (commercially available from G. E.
Silicones), Dow Corning 344, Dow Corning 345 and Dow Corning 200
(commercially available from Dow Corning Corp.), GE 7207 and 7158
(commercially available from General Electric Co.) and SWS-03314
(commercially available from SWS Silicones Corp.).
[0245] Gellant Material. The soft solid can include a gellant
material comprising fatty alcohols having from about 20 to about 60
carbon atoms, or combinations thereof, at concentrations ranging
from about 0.1% to about 8% by weight of the composition. The
gellant material, when combined with the volatile silicone solvent
described herein before, provides the composition with a physically
stable structure within which the particulate antiperspirant
materials are dispersed, and maintained as such over an extended
period of time.
[0246] Specifically, the gellant material can comprise saturated or
unsaturated, substituted or unsubstituted, fatty alcohols or
mixtures of fatty alcohols having from about 20 to about 60 carbons
atoms, preferably from about 20 to about 40 carbon atoms. Preferred
are combinations of the fatty alcohols. The fatty alcohol gellants
are preferably saturated, unsubstituted monohydric alcohols or
combinations thereof, which have a melting point of at less than
about 110.degree. C., more preferably from about 60.degree. to
about 110.degree. C., even more preferably between about
100.degree. C. and 110.degree. C.
[0247] It has been found that this fatty alcohol-based gellant
material, when combined with volatile silicone solvents provides a
stable structure for maintaining a dispersion of particulate
antiperspirant material in a topical formulation without the
necessity of using conventional particulate thickening agents. This
gellant material is especially useful in maintaining the physical
stability of particulate dispersions containing higher
concentrations of volatile silicone solvents.
[0248] It was also found that penetration force values for the
antiperspirant compositions can be controlled by adjusting total
fatty alcohol concentrations. In controlling penetration force
values in this manner, there is no longer a need to use organic
solvents or thickening agents to control penetration force values,
which solvents or thickening agents often add cost to the
formulation, introduce additional compatibility issues, and often
contribute undesirable cosmetics such as prolonged stickiness,
difficulty in ease of spreading, increased dry-down times and
reduced dry feel after application.
[0249] Specific concentrations of the gellant materials can be
selected according to the desired penetration force value. For
roll-on formulations having a penetration force value of from about
20 gramforce to about 100 gramforce, gellant material
concentrations preferably range from about 0.1% to about 3% ,
preferably from about 1.5% to about 3%, by weight of the
antiperspirant composition. For other cream formulations, including
those formulations suitable for use in cream applicator devices,
which have a penetration force value of from about 100 gramforce to
about 500 gramforce, gellant material concentrations preferably
range from about 3% to about 8%, preferably from about 3% to about
6%, by weight of the antiperspirant composition.
[0250] Specific examples of fatty alcohol gellants for use in the
antiperspirant compositions that are commercially available
include, but are not limited to, Unilin.RTM. 425, Unilin.RTM. 350,
Unilin.RTM. 550 and Unilin.RTM. 700 (supplied by Petrolite)
[0251] Residue Masking Material. The soft solid compositions can
further comprise a nonvolatile emollient as a residue masking
material Such materials and their use in antiperspirant products
are well known in the antiperspirant art, and any such material may
be incorporated into the composition of the present invention,
provided that such optional material is compatible with the
essential elements of the composition, or does not unduly impair
product performance or cosmetics.
[0252] Concentrations of the optional residue masking material can
range from about 0.1% to about 40%, preferably from about 1% to
about 10%, by weight of the antiperspirant composition. These
optional materials can be liquid at ambient temperatures, and can
be nonvolatile. The term "nonvolatile" as used in this context
refers to materials which have a boiling point under atmospheric
pressure of at least about 200.degree. C. Nonlimiting examples of
suitable residue masking materials for use in the antiperspirant
products include butyl stearate, diisopropyl adipate, petrolatum,
nonvolatile silicones, octyldodecanol, phenyl trimethicone,
isopropyl myristate, C12-15 ethanol benzoates and PPG-14 Butyl
Ether. Residue masking materials are described, for example, in
U.S. Pat. No. 4,985,238, which description is incorporated herein
by reference.
[0253] Other Materials. The soft solid compositions can further
comprise one, or more, other materials which modify the physical
characteristics of the compositions or serve as additional "active"
components when deposited on the skin. Many such materials are
known in the antiperspirant art and can be used in the
antiperspirant compositions herein, provided that such optional
materials are compatible with the essential materials described
herein, or do not otherwise unduly impair product performance.
[0254] Non limiting examples of materials can include active
components such as bacteriostats and fungiostats, and "non-active"
components such as colorants, fragrances, cosmetic powders,
emulsifiers, chelants, distributing agents, preservatives, and
wash-off aids. Examples of such optional materials are described in
U.S. Pat. No. 4,049,792; Canadian Patent 1,164,347; U.S. Pat. Nos.
5,019,375; and 5,429,816; which descriptions are incorporated
herein by reference.
7.2.6 Aerosol
[0255] An aerosol composition can comprise a concentrate, a
propellant, or a combination thereof. Alcohol is a predominant
component of the concentrates provided herein. Useful alcohols
include C.sub.1-C.sub.3 alcohols, with the preferred alcohol being
ethanol. In certain examples, the alcohol is employed at a
concentration level of from at least about 40%, 50% or 55% to about
80%, by weight of the concentrate.
[0256] An antiperspirant active is dissolved in the alcohol, at a
level of from about 1% to about 15%, by weight of the concentrate.
Various antiperspirant actives can be employed, including, for
example, aluminum chloride, aluminum chlorohydrate, aluminum
chlorohydrex, aluminum chlorohydrex PG, aluminum chlorohydrex PEG,
aluminum dichlorohydrate, aluminum dichlorohydrex PG, aluminum
dichlorohydrex PEG, aluminum sesquichlorohydrate, aluminum
sesquichlorohydrex PG, aluminum sesquichlorohydrex PEG, aluminum
sulfate, aluminum zirconium octachlorohydrate, aluminum zirconium
octachlorohydrex GLY, aluminum zirconium pentachlorohydrate,
aluminum zirconium pentachlorohydrex GLY, aluminum zirconium
tetrachlorohydrate, aluminum zirconium trichlorohydrate, aluminum
zirconium tetrachlorohydrate GLY, and aluminum zirconium
trichlorohydrate GLY. In one example, aluminum chlorohydrex PG is
the chosen antiperspirant active.
[0257] The antiperspirant concentrates can also include an oil or a
mixture of two or more oils. Useful oils include, for example,
volatile silicone oils and non-volatile organic oils. "Volatile
silicone", as used herein, refers to those silicone materials that
have measurable vapor pressure under ambient conditions.
Non-limiting examples of suitable volatile silicones are described
in Todd et al., "Volatile Silicone Fluids for Cosmetics", Cosmetics
and Toiletries, 91:27-32 (1976). The volatile silicone can be a
cyclic silicone having from at least about 3 silicone atoms or from
at least about 5 silicone atoms but no more than about 7 silicone
atoms or no more than about 6 silicone atoms. For example, volatile
silicones can be used which conform to the formula:
##STR00004##
[0258] wherein n is from about 3 or from about 5 but no more than
about 7 or no more than about 6. These volatile cyclic silicones
generally have a viscosity of less than about 10 centistokes at
25.degree. C. Suitable volatile silicones for use herein include,
but are not limited to, Cyclomethicone D5 (commercially available
from G. E. Silicones); Dow Corning 344, and Dow Corning 345
(commercially available from Dow Corning Corp.); and GE 7207, GE
7158 and Silicone Fluids SF-1202 and SF-1173 (available from
General Electric Co.). SWS-03314, SWS-03400, F-222, F-223, F-250,
F-251 (available from SWS Silicones Corp.); Volatile Silicones
7158, 7207, 7349 (available from Union Carbide); MASIL SF-V
(available from Mazer) and combinations thereof. Suitable volatile
silicone oils can also include linear silicone oils such as, for
example, DC200 (1 cSt), DC200 (0.65 cSt), and DC2-1184, all of
which are available from Dow Corning Corp. In certain examples, the
volatile silicone oil can have a viscosity of less than 10
centistokes at 25.degree. C.
[0259] Non-volatile organic, emollient oils can also be employed. A
representative, non-limiting list of emollient oils includes CETIOL
CC (dicaprylyl carbonate), CETIOL OE (dicaprylyl ether), CETIOL S
(diethylhexylcyclohexane), and CETIOL B (dibutyl adipate), all of
which are available from Cognis, and LEXFEEL 7 (neopentyl glycol
diheptanoate) from Inolex. In certain examples, the organic
emollient oils have a viscosity of less than 50 centistokes at
25.degree. C. The term "organic emollient oil" as used herein means
silicon-free emollient oils that are liquid at 25.degree. C., and
that are safe and light to skin and can be miscible with volatile
silicone oils (as described above) and the antiperspirant
active-alcohol solution in the concentration ranges described
below.
[0260] The oil or mixture of oils is generally included in the
concentrate formulas at a level of from about 5% to about 45%, by
weight of the concentrate. This viscosity ranges noted above in
connection with the different classes of oil can facilitate desired
spray rates and patterns, and can help minimize nozzle clogging. To
provide desired skin feel, minimal nozzle clogging, and good
concentrate stability, the ratio of alcohol to volatile silicone
oil is preferably greater than 1.0, 1.35, or 1.5. And in examples
having both a volatile silicone oil and an organic emollient oil,
the ratio of alcohol to total oil is preferably greater than or
equal to about 0.90. The oils in certain examples are miscible with
the alcohol and antiperspirant active solution. Although various
levels of miscibility are acceptable, the oils are preferably
miscible enough with the alcohol and antiperspirant active solution
to yield a concentrate having a clear appearance.
[0261] The antiperspirant compositions can also include
residue-masking agents and propellants as discussed above.
7.3 Personal Care Compositions
[0262] Personal care compositions can include, but are not limited
to, structurants, humectants, fatty acids, inorganic salts, and
other antimicrobial agents or actives.
[0263] A personal care composition can also include hydrophilic
structurants such as carbohydrate structurants and gums. Some
suitable carbohydrate structurants include raw starch (corn, rice,
potato, wheat, and the like) and pregelatinized starch. Some
suitable gums include carrageenan and xanthan gum. A personal care
composition can include from about 0.1% to about 30%, from about 2%
to about 25%, or from about 4% to about 20%, by weight of the
personal care composition, of a carbohydrate structurant.
[0264] A personal care composition can also include one or more
humectants. Examples of such humectants can include polyhydric
alcohols. Further, humectants such as glycerin can be included the
personal care composition as a result of production or as an
additional ingredient. For example, glycerin can be a by-product
after saponification of the personal care composition. Including
additional humectant can result in a number of benefits such as
improvement in hardness of the personal care composition, decreased
water activity of the personal care composition, and reduction of a
weight loss rate of the personal care composition over time due to
water evaporation.
[0265] A personal care composition can include inorganic salts.
Inorganic salts can help to maintain a particular water content or
level of the personal care composition and improve hardness of the
personal care composition. The inorganic salts can also help to
bind the water in the personal care composition to prevent water
loss by evaporation or other means. A personal care composition can
optionally include from about 0.01% to about 15%, from about 1% to
about 12%, or from about 2.5% to about 10.5%, by weight of the
personal care composition, of inorganic salt. Examples of suitable
inorganic salts can include magnesium nitrate, trimagnesium
phosphate, calcium chloride, sodium carbonate, sodium aluminum
sulfate, disodium phosphate, sodium polymetaphosphate, sodium
magnesium succinate, sodium tripolyphosphate, aluminum sulfate,
aluminum chloride, aluminum chlorohydrate, aluminum-zirconium
trichlorohydrate, aluminum-zirconium trichlorohydrate glycine
complex, zinc sulfate, ammonium chloride, ammonium phosphate,
calcium acetate, calcium nitrate, calcium phosphate, calcium
sulfate, ferric sulfate, magnesium chloride, magnesium sulfate, and
tetrasodium pyrophosphate.
[0266] A personal care composition can include one or more
additional antibacterial agents that can serve to further enhance
antimicrobial effectiveness of the personal care composition. A
personal care composition can include, for example, from about
0.001% to about 2%, from about 0.01% to about 1.5%, or from about
0.1% to about 1%, by weight of the personal care composition, of
additional antibacterial agent(s). Examples of suitable
antibacterial agents can include carbanilides, triclocarban (also
known as trichlorocarbanilide), triclosan, a halogenated
diphenylether available as DP-300 from Ciba-Geigy, hexachlorophene,
3,4,5-tribromosalicylanilide, and salts of 2-pyridinethiol-1-oxide,
salicylic acid, and other organic acids. Other suitable
antibacterial agents are described in U.S. Pat. No. 6,488,943.
7.3.1 Scalp Active Material

composition may comprise a scalp active material, which may be an
anti-dandruff active. In an embodiment, the anti-dandruff active is
selected from the group consisting of: pyridinethione salts; zinc
carbonate; azoles, such as ketoconazole, econazole, and elubiol;
selenium sulfide; particulate sulfur; keratolytic agents such as
salicylic acid; and mixtures thereof In a further embodiment, the
anti-dandruff active may be an anti-dandruff particulate. In an
embodiment, the anti-dandruff particulate is a pyridinethione salt.
Such anti-dandruff particulate should be physically and chemically
compatible with the components of the composition, and should not
otherwise unduly impair product stability, aesthetics or
performance.
[0268] Pyridinethione particulates are suitable particulate
anti-dandruff actives for use in composition of the present
invention. In an embodiment, the anti-dandruff active is a
1-hydroxy-2-pyridinethione salt and is in particulate form. In an
embodiment, the concentration of pyridinethione anti-dandruff
particulate ranges from about 0.01% to about 5%, by weight of the
composition, or from about 0.1% to about 3%, or from about 0.1% to
about 2%. In an embodiment, the pyridinethione salts are those
formed from heavy metals such as zinc, tin, cadmium, magnesium,
aluminium and zirconium, generally zinc, typically the zinc salt of
1-hydroxy-2-pyridinethione (known as "zinc pyridinethione" or
"ZPT"; zinc pyrithione), commonly 1-hydroxy-2-pyridinethione salts
in platelet particle form. In an embodiment, the
1-hydroxy-2-pyridinethione salts in platelet particle form have an
average particle size of up to about 20 microns, or up to about 5
microns, or up to about 2.5 microns. Salts formed from other
cations, such as sodium, may also be suitable. Pyridinethione
anti-dandruff actives are described, for example, in U.S. Pat. Nos.
2,809,971; 3,236,733; 3,753,196; 3,761,418; 4,345,080; 4,323,683;

[0269] In an embodiment, in addition to the anti-dandruff active
selected from polyvalent metal salts of pyrithione, the composition
further comprises one or more anti-fungal and/or anti-microbial
actives. In an embodiment, the anti-microbial active is selected
from the group consisting of: coal tar, sulfur, charcoal,

[0270] In an embodiment, the azole anti-microbials is an imidazole
selected from the group consisting of: benzimidazole,
benzothiazole, bifonazole, butaconazole nitrate, climbazole,
clotrimazole, croconazole, eberconazole, econazole, elubiol,
fenticonazole, fluconazole, flutimazole, isoconazole, ketoconazole,
lanoconazole, metronidazole, miconazole, neticonazole, omoconazole,
oxiconazole nitrate, sertaconazole, sulconazole nitrate,
tioconazole, thiazole, and mixtures thereof, or the azole
anti-microbials is a triazole selected from the group consisting
of: terconazole, itraconazole, and mixtures thereof. When present
in the composition, the azole anti-microbial active is included in
an amount of from about 0.01% to about 5%, or from about 0.1% to
about 3%, or from about 0.3% to about 2%, by total weight of the
composition. In an embodiment, the azole anti-microbial active is
ketoconazole. In an embodiment, the sole anti-microbial active is
ketoconazole.
[0271] The present invention may also comprise a combination of
anti-microbial actives. In an embodiment, the combination of
anti-microbial active is selected from the group of combinations
consisting of: octopirox and zinc pyrithione, pine tar and sulfur,
salicylic acid and zinc pyrithione, salicylic acid and elubiol,
zinc pyrithione and elubiol, zinc pyrithione and climbasole,
octopirox and climbasole, salicylic acid and octopirox, and
mixtures thereof.
[0272] In an embodiment, the composition comprises an effective
amount of a zinc-containing layered material. In an embodiment, the
composition comprises from about 0.001% to about 10%, or from about
0.01% to about 7%, or from about 0.1% to about 5% of a
zinc-containing layered material, by total weight of the
composition.
[0273] Zinc-containing layered materials may be those with crystal
growth primarily occurring in two dimensions. It is conventional to
describe layer structures as not only those in which all the atoms
are incorporated in well-defined layers, but also those in which
there are ions or molecules between the layers, called gallery ions
(A. F. Wells "Structural Inorganic Chemistry" Clarendon Press,
1975). Zinc-containing layered materials (ZLMs) may have zinc
incorporated in the layers and/or be components of the gallery
ions. The following classes of ZLMs represent relatively common
examples of the general category and are not intended to be
limiting as to the broader scope of materials which fit this
definition.
[0274] Many ZLMs occur naturally as minerals. In an embodiment, the
ZLM is selected from the group consisting of: hydrozincite (zinc
carbonate hydroxide), basic zinc carbonate, aurichalcite (zinc
copper carbonate hydroxide), rosasite (copper zinc carbonate
hydroxide), and mixtures thereof. Related minerals that are
zinc-containing may also be included in the composition. Natural
ZLMs can also occur wherein anionic layer species such as clay-type
minerals (e.g., phyllosilicates) contain ion-exchanged zinc gallery
ions. All of these natural materials can also be obtained
synthetically or formed in situ in a composition or during a
production process.
[0275] Another common class of ZLMs, which are often, but not
always, synthetic, is layered double hydroxides. In an embodiment,
the ZLM is a layered double hydroxide conforming to the formula
[M.sup.2+.sub.1-xM.sup.3+.sub.x(OH).sub.2].sup.x+
A.sup.m-.sub.x/m.nH.sub.2O wherein some or all of the divalent ions
(M.sup.2+) are zinc ions (Crepaldi, E L, Pava, PC, Tronto, J,
Valim, J B J. Colloid Interfac. Sci. 2002, 248, 429-42).
[0276] Yet another class of ZLMs can be prepared called hydroxy
double salts (Morioka, H., Tagaya, H., Karasu, M, Kadokawa, J,
Chiba, K Inorg. Chem. 1999, 38, 4211-6). In an embodiment, the ZLM
is a hydroxy double salt conforming to the formula
[M.sup.2+.sub.1-xM.sup.2+.sub.1+x(OH).sub.3(1-y)].sup.+
A.sup.n-.sub.(1-3y)/n.H.sub.2O where the two metal ions (M.sup.2+)
may be the same or different. If they are the same and represented
by zinc, the formula simplifies to
[Zn.sub.1+x(OH).sub.2].sup.2x+2xA.sup.-.nH.sub.2O. This latter
formula represents (where x=0.4) materials such as zinc
hydroxychloride and zinc hydroxynitrate. In an embodiment, the ZLM
is zinc hydroxychloride and/or zinc hydroxynitrate. These are
related to hydrozincite as well wherein a divalent anion replace
the monovalent anion. These materials can also be formed in situ in
a composition or in or during a production process.
[0277] In an embodiment, the composition comprises basic zinc
carbonate. Commercially available sources of basic zinc carbonate
include Zinc Carbonate Basic (Cater Chemicals: Bensenville, Ill.,
USA), Zinc Carbonate (Shepherd Chemicals: Norwood, Ohio, USA), Zinc
Carbonate (CPS Union Corp.: New York, N.Y., USA), Zinc Carbonate
(Elementis Pigments: Durham, UK), and Zinc Carbonate AC (Bruggemann
Chemical: Newtown Square, Pa., USA). Basic zinc carbonate, which
also may be referred to commercially as "Zinc Carbonate" or "Zinc
Carbonate Basic" or "Zinc Hydroxy Carbonate", is a synthetic
version consisting of materials similar to naturally occurring
hydrozincite. The idealized stoichiometry is represented by
Zn.sub.5(OH).sub.6(CO.sub.3).sub.2 but the actual stoichiometric
ratios can vary slightly and other impurities may be incorporated
in the crystal lattice.
[0278] In embodiments having a zinc-containing layered material and
a pyrithione or polyvalent metal salt of pyrithione, the ratio of
zinc-containing layered material to pyrithione or a polyvalent
metal salt of pyrithione is from about 5:100 to about 10:1, or from
about 2:10 to about 5:1, or from about 1:2 to about 3:1.
7.3.2 Liquid Personal Care Compositions
[0279] Exemplary liquid rinse-off personal care compositions can
include an aqueous carrier, which can be present at a level of from
about 5% to about 95%, or from about 60% to about 85%. The aqueous
carrier may comprise water, or a miscible mixture of water and
organic solvent. Non-aqueous carrier materials can also be
employed.
[0280] Such rinse-off personal care compositions can include one or
more detersive surfactants. The detersive surfactant component can
be included to provide cleaning performance to the product. The
detersive surfactant component in turn comprises anionic detersive
surfactant, zwitterionic or amphoteric detersive surfactant, or a
combination thereof. A representative, non-limiting, list of
anionic surfactants includes anionic detersive surfactants for use
in the compositions can include ammonium lauryl sulfate, ammonium
laureth sulfate, triethylamine lauryl sulfate, triethylamine
laureth sulfate, triethanolamine lauryl sulfate, triethanolamine
laureth sulfate, monoethanolamine lauryl sulfate, monoethanolamine
laureth sulfate, diethanolamine lauryl sulfate, diethanolamine
laureth sulfate, lauric monoglyceride sodium sulfate, sodium lauryl
sulfate, sodium laureth sulfate, potassium lauryl sulfate,
potassium laureth sulfate, sodium lauryl sarcosinate, sodium
lauroyl sarcosinate, lauryl sarcosine, cocoyl sarcosine, ammonium
cocoyl sulfate, ammonium lauroyl sulfate, sodium cocoyl sulfate,
sodium lauroyl sulfate, potassium cocoyl sulfate, potassium lauryl
sulfate, triethanolamine lauryl sulfate, triethanolamine lauryl
sulfate, monoethanolamine cocoyl sulfate, monoethanolamine lauryl
sulfate, sodium tridecyl benzene sulfonate, sodium dodecyl benzene
sulfonate, sodium cocoyl isethionate and combinations thereof In
one example, the anionic surfactant can be sodium lauryl sulfate or
sodium laureth sulfate. The concentration of the anionic surfactant
component in the product can be sufficient to provide a desired
cleaning and/or lather performance, and generally ranges from about
2% to about 50%. Amphoteric detersive surfactants suitable for use
in the rinse-off personal care compositions are well known in the
art, and include those surfactants broadly described as derivatives
of aliphatic secondary and tertiary amines in which an aliphatic
radical can be straight or branched chain and wherein an aliphatic
substituent can contain from about 8 to about 18 carbon atoms such
that one carbon atom can contain an anionic water solubilizing
group, e.g., carboxy, sulfonate, sulfate, phosphate, or
phosphonate. Examples of compounds falling within this definition
can be sodium 3-dodecyl-aminopropionate, sodium
3-dodecylaminopropane sulfonate, sodium lauryl sarcosinate,
N-alkyltaurines such as the one prepared by reacting dodecylamine
with sodium isethionate according to the teaching of U.S. Pat. No.
2,658,072, N-higher alkyl aspartic acids such as those produced
according to the teaching of U.S. Pat. No. 2,438,091, and products
described in U.S. Pat. No. 2,528,378. Other examples of amphoteric
surfactants can include sodium lauroamphoacetate, sodium
cocoamphoactetate, disodium lauroamphoacetate disodium
cocodiamphoacetate, and mixtures thereof. Amphoacetates and
diamphoacetates can also be used.
[0281] Zwitterionic detersive surfactants suitable for use in the
rinse-off personal care compositions are well known in the art, and
include those surfactants broadly described as derivatives of
aliphatic quaternary ammonium, phosphonium, and sulfonium
compounds, in which aliphatic radicals can be straight or branched
chains, and wherein an aliphatic substituent can contain from about
8 to about 18 carbon atoms such that one carbon atom can contain an
anionic group, e.g., carboxy, sulfonate, sulfate, phosphate, or
phosphonate. Other zwitterionic surfactants can include betaines,
including cocoamidopropyl betaine.
[0282] The liquid rinse off personal care composition can comprise
one or more phases. Such personal care compositions can include a
cleansing phase and/or a benefit phase (i.e., a single- or
multi-phase composition). Each of a cleansing phase or a benefit
phase can include various components. The cleansing phase and the
benefit phase can be blended, separate, or a combination thereof.
The cleansing phase and the benefit phase can also be patterned
(e.g. striped).
[0283] The cleansing phase of a personal care composition can
include at least one surfactant. The cleansing phase can be an
aqueous structured surfactant phase and constitute from about 5% to
about 20%, by weight of the personal care composition. Such a
structured surfactant phase can include sodium trideceth(n)
sulfate, hereinafter STnS, wherein n can define average moles of
ethoxylation. n can range, for example, from about 0 to about 3;
from about 0.5 to about 2.7, from about 1.1 to about 2.5, from
about 1.8 to about 2.2, or n can be about 2. When n can be less
than 3, STnS can provide improved stability, improved compatibility
of benefit agents within the personal care compositions, and
increased mildness of the personal care compositions as disclosed
in U.S. Pre-Grant Publication No. 2010/009285 A1.
[0284] The cleansing phase can also comprise at least one of an
amphoteric surfactant and a zwitterionic surfactant. Suitable
amphoteric or zwitterionic surfactants (in addition to those cited
herein) can include, for example, those described in U.S. Pat. Nos.
5,104,646 and 5,106,609.
[0285] A cleansing phase can comprise a structuring system. A
structuring system can comprise, optionally, a non-ionic
emulsifier, optionally, from about 0.05% to about 5%, by weight of
the personal care composition, of an associative polymer; and an
electrolyte.
[0286] The personal care composition can optionally be free of
sodium lauryl sulfate, hereinafter SLS, and can comprise at least a
70% lamellar structure. However, the cleansing phase could comprise
at least one surfactant, wherein the at least one surfactant
includes SLS. Suitable examples of SLS are described in U.S.
Pre-Grant Publication No. 2010/0322878 A1.
[0287] Rinse-off personal care compositions can also include a
benefit phase. The benefit phase can be hydrophobic and/or
anhydrous. The benefit phase can also be substantially free of
surfactant. A benefit phase can also include a benefit agent. In
particular, a benefit phase can comprise from about 0.1% to about
50% benefit agent by weight of the personal care composition. The
benefit phase can alternatively comprise less benefit agent, for
example, from about 0.5% to about 20% benefit agent, by weight of
the personal care composition. Examples of suitable benefit agents
can include petrolatum, glyceryl monooleate, mineral oil, natural
oils, and mixtures thereof. Additional examples of benefit agents
can include water insoluble or hydrophobic benefit agents. Other
suitable benefit agents are described in U.S. Pre-Grant Publication
No. 2012/0009285 A1.
[0288] Non-limiting examples of glycerides suitable for use as
hydrophobic skin benefit agents herein can include castor oil,
safflower oil, corn oil, walnut oil, peanut oil, olive oil, cod
liver oil, almond oil, avocado oil, palm oil, sesame oil, vegetable
oils, sunflower seed oil, soybean oil, vegetable oil derivatives,
coconut oil and derivatized coconut oil, cottonseed oil and
derivatized cottonseed oil, jojoba oil, cocoa butter, and
combinations thereof.
[0289] Non-limiting examples of alkyl esters suitable for use as
hydrophobic skin benefit agents herein can include isopropyl esters
of fatty acids and long chain esters of long chain (i.e. C10-C24)
fatty acids, e.g., cetyl ricinoleate, non-limiting examples of
which can include isopropyl palmitate, isopropyl myristate, cetyl
riconoleate, and stearyl riconoleate. Other example can include
hexyl laurate, isohexyl laurate, myristyl myristate, isohexyl
palmitate, decyl oleate, isodecyl oleate, hexadecyl stearate, decyl
stearate, isopropyl isostearate, diisopropyl adipate, diisohexyl
adipate, dihexyldecyl adipate, diisopropyl sebacate, acyl
isononanoate lauryl lactate, myristyl lactate, cetyl lactate, and
combinations thereof.
[0290] Non-limiting examples of polyglycerin fatty acid esters
suitable for use as hydrophobic skin benefit agents herein can
include decaglyceryl distearate, decaglyceryl diisostearate,
decaglyceryl monomyriate, decaglyceryl monolaurate, hexaglyceryl
monooleate, and combinations thereof.
[0291] The rinse-off personal care composition can be applied by a
variety of means, including by rubbing, wiping or dabbing with
hands or fingers, or by means of an implement and/or delivery
enhancement device. Non-limiting examples of implements include a
sponge or sponge-tipped applicator, a mesh shower puff, a swab, a
brush, a wipe (e.g., wash cloth), a loofah, and combinations
thereof. Non-limiting examples of delivery enhancement devices
include mechanical, electrical, ultrasonic and/or other energy
devices. Employment of an implement or device can help delivery of
the particulate antimicrobial agent to target regions, such as, for
example, hair follicles and undulations that can exist in the
underarm. The rinse-off care product can be sold together with such
an implement or device. Alternatively, an 071950.0419CON implement
or device can be sold separately but contain indicium to indicate
usage with a rinse-off care product. Implements and delivery
devices can employ replaceable portions (e.g., the skin interaction
portions), which can be sold separately or sold together with the
rinse-off care product in a kit.
7.3.3 Solid Personal Care Compositions
[0292] As noted herein, personal care compositions can take on
numerous forms. One suitable form is that of a solid personal care
composition. Solid compositions can take many forms like powder,
pellets, bars, etc. These forms will generally be described herein
as bar soap, but it should be understood that the solid composition
could be in another form or shape. One example of a bar soap
personal care composition can include from about 0.1% to about 35%,
by weight of the personal care composition, of water, from about
45% to about 99%, by weight of the personal care composition, of
soap, and from about 0.01% to about 5%, by weight of the personal
care composition, of a particulate antimicrobial agent. Another
suitable antimicrobial bar soap can include, for example, from
about 0.1% to about 30%, by weight of the personal care
composition, of water, from about 40% to about 99%, by weight of
the personal care composition, of soap, and from about 0.25% to
about 3%, by weight of the personal care composition, of a
particulate antimicrobial agent.
[0293] Bar soap compositions can be referred to as conventional
solid (i.e. non-flowing) bar soap compositions. Some bar soap
composition can comprise convention soap, while others can contain
synthetic surfactants, and still others can contain a mix of soap
and synthetic surfactant.
[0294] Bar compositions can include, for example, from about 0% to
about 45% of a synthetic anionic surfactant. An example of a
suitable conventional soap can include milled toilet bars that are
unbuilt (i.e. include about 5% or less of a water-soluble
surfactancy builder).
[0295] A personal care bar composition can include soap. By weight,
the soap can be, for example, from about 45% to about 99%, or from
about 50% to about 75%, by weight of the personal care composition.
Such soaps can include a typical soap, i.e., an alkali metal or
alkanol ammonium salt of an alkane- or alkene monocarboxylic acid.
Sodium, magnesium, potassium, calcium, mono-, di- and tri-ethanol
ammonium cations, or combinations thereof, can be suitable for a
personal care composition. The soap included in a personal care
composition can include sodium soaps or a combination of sodium
soaps with from about 1% to about 25% ammonium, potassium,
magnesium, calcium, or a mixture of these soaps. Additionally, the
soap can be well-known alkali metal salts of alkanoic or alkenoic
acids having from about 12 to about 22 carbon atoms or from about
12 to about 18 carbon atoms. Another suitable soap can be alkali
metal carboxylates of alkyl or alkene hydrocarbons having from
about 12 to about 22 carbon atoms. Additional suitable soap
compositions are described in U.S. Pre-Grant Publication No.
2012/0219610 A1.
[0296] A personal care composition can also include soaps having a
fatty acid. For example, one bar soap composition could contain
from about 40% to about 95% of a soluble alkali metal soap of
C.sub.8-C.sub.24 or C.sub.10-C.sub.20 fatty acids. The fatty acid
can, for example, have a distribution of coconut oil that can
provide a lower end of a broad molecular weight range or can have a
fatty acid distribution of peanut or rapeseed oil, or their
hydrogenated derivatives, which can provide an upper end of the
broad molecular weight range. Other such compositions can include a
fatty acid distribution of tallow and/or vegetable oil. The tallow
can include fatty acid mixtures that can typically have an
approximate carbon chain length distribution of 2.5% C.sub.14, 29%
C.sub.16, 23% C.sub.18, 2% palmitoleic, 41.5% oleic, and 3%
linoleic. The tallow can also include other mixtures with a similar
distribution, such as fatty acids derived from various animal
tallows and/or lard. In one example, the tallow can also be
hardened (i.e., hydrogenated) such that some or all unsaturated
fatty acid moieties can be converted to saturated fatty acid
moieties.
[0297] Suitable examples of vegetable oil include palm oil, coconut
oil, palm kernel oil, palm oil stearine, soybean oil, and
hydrogenated rice bran oil, or mixtures thereof, since such oils
can be among more readily available fats. One example of a suitable
coconut oil can include a proportion of fatty acids having at least
12 carbon atoms of about 85%. Such a proportion can be greater when
mixtures of coconut oil and fats such as tallow, palm oil, or
non-tropical nut oils or fats can be used where principle chain
lengths can be C.sub.16 and higher. The soap included in a personal
care composition can be, for example, a sodium soap having a
mixture of about 67-68% tallow, about 16-17% coconut oil, about 2%
glycerin, and about 14% water.
[0298] Soap included in a personal care composition can also be
unsaturated in accordance with commercially acceptable standards.
For example, a soap included in a personal care composition can
include from about 37% to about 45% unsaturated saponified
material.
[0299] Soaps included in a personal care composition can be made,
for example, by a classic kettle boiling process or modern
continuous soap manufacturing processes wherein natural fats and
oils such as tallow or coconut oil or their equivalents can be
saponified with an alkali metal hydroxide using procedures well
known to those skilled in the art. Soap can also be made by
neutralizing fatty acids such as lauric (C.sub.12), myristic
(C.sub.14), palmitic (C.sub.16), or stearic (C18) acids, with an
alkali metal hydroxide or carbonate.
[0300] Soap included in a personal care composition could also be
made by a continuous soap manufacturing process. The soap could be
processed into soap noodles via a vacuum flash drying process. One
example of a suitable soap noodle comprises about 67.2% tallow
soap, about 16.8% coconut soap, about 2% glycerin, and about 14%
water, by weight of the soap noodle. The soap noodles can then be
utilized in a milling process to finalize a personal care
composition.

Example 4: Influence of Musk Compounds On Salivary Alpha-Amylase
Levels
[0305] Salivary alpha-amylase is widely used as a biomarker for
acute stress. The purpose of this study was to investigate the
influence of individual fragrance compounds, particularly musk
compounds, on a subject's salivary alpha-amylase levels before and
after exposure to a stressor. The subject sniffed each musk
compound, then was exposed to a stressor. The goal was to identify
one or more specific musk compounds which caused the least amount
of change in salivary alpha-amylase levels or decreased a subject's
salivary alpha-amylase levels compared to before administration,
thereby reducing or inhibiting a response to stress stimuli. The
results are summarized in FIG. 1, which shows the percent change in
salivary alpha-amylase levels after inhaling various fragrance
compounds, as compared to the percent change in salivary
alpha-amylase levels after inhaling a control (dipropylene glycol).
The p values of the control as compared to each musk compound were
calculated as follows: rosamusk (p=0.0366), habanolide (p=0.1163),
ambrettolide (p=0.1397).
Example 5: Influence of Musk Compounds On Salivary Cortisol
Levels
[0306] Salivary cortisol is widely used as a biomarker for stress.
The purpose of this study was to investigate the influence of
individual fragrance compounds, particularly musk compounds, on a
subject's cortisol levels before and after exposure to a stressor.
The subject sniffed each musk compound, then was exposed to a
stressor. The goal was to identify one or more specific musk
compounds which caused the least amount of change in cortisol
levels or decreased a subject's cortisol levels compared to before
administration, thereby reducing or inhibiting a response to stress
stimuli. The results are summarized in FIG. 2, which shows the
percent change in salivary cortisol levels after inhaling various
fragrance compounds, as compared to the percent change in salivary
cortisol levels after inhaling a control (dipropylene glycol).
Example 6: Influence of Macrocyclic Musk Compounds On Salivary
Alpha-Amylase Levels
[0307] This Example evaluated the effects of several macrocylic
musk compounds on salivary alpha-amylase levels of a test
group.
[0308] Twelve to fourteen female panelists age 30-45 participated
in this study for each of the test materials. Stress was induced
using a timed ten minute mathematical/word test in a small group
competition setting. The musk material was introduced at intervals
during the stress test.
[0309] Saliva was collected before and immediately after the stress
test. Saliva samples were assayed for salivary alpha-amylase
activity using a commercially available kinetic reaction assay kit
(Salimetrics.RTM., State College, Pa.).
[0310] The change in a panelist's salivary alpha-amylase level for
each tested musk compound is summarized in Table 4.
TABLE-US-00004 TABLE 4 Summary of salivary alpha-amylase level for
each tested musk compound. Percent change in Musk Compound salivary
alpha-amylase Solvent only (control) 66.8% Musk T .RTM. 47.1%

(9Z)-17-oxacycloheptadec-6-en-1-one Habanolide .RTM. 4.7%
(12E)-1-oxacyclohexadec-12-en-2-one
[0311] Results in Table 4 show that salivary alpha-amylase levels
in the control sample increased by nearly 67%. However, the data
shows that the use of these individual macrocyclic musk compounds
resulted in substantially lower salivary alpha-amylase levels after
the stress test. Therefore, the data demonstrated that the
inhalation of these macrocyclic musk compounds inhibited the
increase of salivary alpha-amylase under stress.
Example 7: Influence of Non-Macrocyclic Musk Compounds on Salivary
Alpha-Amylase Levels
[0312] This Example evaluated the effects of two non-macrocyclic
musk compounds on salivary alpha-amylase levels of a test
group.
[0313] Materials and methods were the same as Example 6. The change
in a panelist's salivary alpha-amylase level for each tested musk
compound is summarized in Table 5.
TABLE-US-00005 TABLE 5 Summary of salivary alpha-amylase level for
each tested musk compound. Percent change in Musk Compound salivary
alpha-amylase Solvent only (control) 66.8% Hindinol .RTM. 82.3%

ethyl (1R,6S)-2,2,6-trimethylcyclohexane-1- 70.7% carboxylate
[0314] Results in Table 5 show that salivary alpha-amylase levels
for two specific non-macrocyclic musk compounds increased as much
as or more than the control solvent. Therefore, inhalation of these
two non-macrocyclic musk compounds individually did not inhibit the
increase of salivary alpha-amylase under stress.
Example 8: The Influence of Musk Compound Musk T on Salivary
Alpha-Amylase and
[0315] Cortisol Reactivity to Acute Stress
[0316] Fourteen female panelists age 30-45 participated in this
study. Stress was induced using a timed ten minute
mathematical/word test in a small group competition setting.
Fragrance was introduced at intervals during the stress test.
Saliva was collected before (Pre) and immediately after (Post) the
stress test. Saliva samples were assayed for salivary alpha-amylase
using a commercially available kinetic reaction assay kit and for
salivary cortisol using a highly sensitive enzyme immunoassay kit
(Salimetrics.RTM., State College, Pa.).
[0317] The Musk T compound was formulated in a fragrance at an
amount of 2.5% by weight for use in the present example. 75% by
weight of a floral fragrance was admixed with 25% by weight Musk T
to form an admixture. 10% of the admixture was then diluted with
90% DPG to form a musk containing fragrance.
[0318] As shown in FIG. 3, Pre vs. Post salivary alpha-amylase
level increased in response to the stress test, 38% with fragrance
and 120% with DPG alone.
[0319] As shown in FIG. 4, Pre vs. Post salivary cortisol level in
response to the stress test decreased 8% with fragrance and
increased 24% with DPG alone.
[0320] The increase of salivary alpha-amylase during the stress
test in the presence of the Musk T compound was less than the
control. With regard to changes in cortisol during the stress test,
in the presence of Musk T, there was a decrease in cortisol levels,
which is in contrast to the increase observed for the control. The
results of this study demonstrate that the presence of
[0321] Musk T during a stress task has a positive influence by
blunting the effect of the stressor and that both the sympathetic
and the HPA axis may be involved.
Example 9: The Influence of Musk Compound Musk T on Brain Wave
Function and Salivary Alpha-Amylase and Cortisol Reactivity to
Acute Stress
[0322] This study was conducted using the methods as described
above for Example 8. The Musk T compound was formulated in an
amount of 10% by weight in DPG for use as a musk containing
fragrance in the present example.
[0323] Contingent Negative Variant (CNV) analysis was conducted on
brain waves recorded from subjects using EEG
(electroencephalography) in the presence of the musk fragrance
compound. CNV analysis is summarized in Okazaki et al., Proceedings
of the 13th International Congress of Flavours, Fragrances and
Essential Oils, 15-19 Oct. 1995.
[0324] As shown in FIG. 5, Pre vs. Post salivary alpha-amylase
level increased in response to the stress test, 47% with fragrance
and 161% with DPG alone.
[0325] As shown in FIG. 6, Pre vs. Post salivary cortisol level
increased in response to the stress test, 10% with fragrance and
41% with DPG alone.
[0326] Contingent Negative Variant (CNV) analysis of brain waves in
subjects exposed to the fragrance shows a 32.5% increase in the
level of relaxation when exposed to the fragrance.
[0327] The increase of salivary alpha-amylase during the stress
test in the presence of Musk T was less than the control.
Similarly, the increase in cortisol levels during the stress test
was lower in the presence of Musk T than control. Furthermore, CNV
analysis of EEG data from subjects exposed to Musk T identified an
increase in brain waves associated with an emotional state of
relaxation. The results of this study demonstrate that the presence
of a Musk T fragrance during a stress task has a positive influence
by blunting the effect of the stressor and that both the
sympathetic and the HPA axis may be involved.
Example 10: The Influence of Rosamusk on Salivary Alpha-Amylase and
Cortisol Reactivity to Acute Stress
[0328] The study was conducted using the methods as described above
for Example 8. The Rosamusk compound was formulated in an amount of
10% by weight in DPG for use as a musk containing fragrance in the
present example.
[0329] As shown in FIG. 7, Pre vs. Post salivary alpha-amylase
level in response to the stress test decreased 15% with fragrance
and increased 33% with DPG alone.
[0330] As shown in FIG. 8, Pre vs. Post salivary cortisol level
increased in response to the stress test, 7% with fragrance and 25%
with DPG alone.
[0331] During the stress test, the level of salivary alpha-amylase
in the presence of Rosamusk decreased, while the level of salivary
alpha-amylase increased for the control. With regard to changes in
cortisol during the stress test, the increase in cortisol level
during the stress test was lower in the presence of Rosamusk than
control. The results of this study demonstrate that the presence of
Rosamusk during a stress task has a positive influence by blunting
the effect of the stressor and that both the sympathetic and the
HPA axis may be involved.
Example 11: The Influence of Musk Compound Musk T on Salivary
Alpha-Amylase and Cortisol Reactivity to Acute Stress and Consumer
Self-Report Assay of Emotional State
[0332] The study was conducted using the methods as described above
for Example 8.
[0333] In the present example, 54% by weight of a floral fragrance
was admixed with 46% by weight Musk T to form an admixture. 10% of
the admixture was then diluted with 90% by weight DPG to form the
musk containing fragrance. Therefore, the Musk T compound was
prepared in an amount of 4.6% by weight in the overall fragrance
composition.
[0334] In addition to measuring salivary alpha-amylase level and
cortisol level before and after the stress test in the presence or
absence of a musk fragrance compound, a panel of consumers (N=15)
provided a consumer self-report regarding their emotional state
after exposure to the fragrance. The panelists also conducted a
self-reported measurement of emotion, as determined by a PANAS
(Positive Affect Negative Affect Scale) questionnaire.
[0335] As shown in FIG. 9, Pre vs. Post salivary cortisol level in
response to the stress test decreased 11% with fragrance and
increased 4% with DPG alone.
[0336] The Pre vs. Post salivary alpha-amylase level in response to
the stress test increase 35.3% with fragrance and increased 50.8%
with DPG alone.
[0337] In the consumer self-report questionnaire, 100% of panelists
felt "at ease," "relaxed" and "calm" after exposure to the
fragrance.
[0338] With regard to the consumer self-report PANAS assay, there
was a decrease of 6.4% in stimulating attributes after exposure to
the fragrance.
[0339] With regard to changes in salivary alpha-amylase before and
after the stress test, in the presence of the Musk T fragrance,
there was an increase in salivary alpha-amylase levels. However,
the increase of the control (DPG alone) was much higher than that
with the Musk T fragrance (35.3% compared to 50.8% DPG alone).
[0340] Similarly, according to the consumer report questionnaires,
the Musk T fragrance resulted in emotional states of relaxation,
with a decrease in stimulating attributes. The results of this
study demonstrate that the presence of the Musk T fragrance during
a stress task has a positive influence by blunting the effect of
the stressor and that both the sympathetic and the HPA axis may be
involved.
Example 12: The Influence of Formulation B on Salivary
Alpha-Amylase and Salivary Cortisol Levels
[0341] This study was conducted using Formulation B as described
above for Example 2. A fragrance composition was prepared using 10%
w/w of Formulation B admixed with 90% w/w of a fruity fragrance
composition. Salivary samples were taken before and after a stress
test.
[0342] As shown in FIG. 10, salivary alpha-amylase levels were
lower in response to the combination of Formulation B and the
fruity fragrance composition versus the fruity fragrance
composition alone.
[0343] As shown in FIG. 11, salivary cortisol levels were lower in
response to the combination of Formulation B and the fruity
fragrance composition versus the fruity fragrance composition
alone.
[0344] As shown in FIG. 12, salivary cortisol levels were lower in
response to the combination of Formulation B and the fruity
fragrance composition versus the fruity fragrance composition alone
and versus solvent alone.
[0345] The results of this study demonstrate that both salivary
alpha-amylase and salivary cortisol levels decrease in the presence
of Formulation B in combination with the fruity fragrance
composition more than in the presence of the fruity fragrance
composition alone. Therefore, the data demonstrated that the
combination of Formulation B and the fruity fragrance composition
inhibited the increase of salivary alpha-amylase and salivary
cortisol under stress.
Example 13: Compounds Effective Against Stressors
[0346] The present Example provides the results of those compounds
that demonstrated a change in salivary amylase levels, cortisol
levels, or both. Dipropylene glycol (DPG) was used as the solvent
and control.
[0347] Stress was induced in a number of panelists (about 10-15)
for each tested compound using a timed ten minute mathematical/word
test in a small group competition setting. The test compound was
introduced at intervals during the stress test.
[0348] Saliva was collected before and immediately after the stress
test. Saliva samples were assayed for salivary cortisol levels and
salivary alpha-amylase activity using a commercially available
kinetic reaction assay kit (Salimetrics.RTM., State College,
Pa.).
[0349] The change in a panelist's salivary alpha-amylase and
salivary cortisol levels for each tested compound is summarized in
Table 6.

Example 14: The Influence of Formulation A on Salivary
Alpha-Amylase and Salivary Cortisol Levels
[0351] This study was conducted using Formulation A as described
above for Example 1. A fragrance composition was prepared using 10%
w/w of Formulation A admixed with 90% w/w of a fragrance
composition. Salivary samples were taken before and after a stress
test to evaluate alpha-amylase and cortisol inhibition. The
participants were exposed to Formulation A in the fragrance
composition at different time points including, before application
of the stressor, during the duration of the stressor and during
only the first half of exposure to the stressor. The sniff time
points and results are summarized in Table 7.
TABLE-US-00007 TABLE 7 Summary of alpha-amylase and cortisol
inhibition before and during a stress test. Percent change in
Percent change in Event alpha amylase cortisol Solvent only

(normal procedure) Sniff only 5 times during 54.06% -3.52% first
half of stressor Sniff only before stressor -26.08% 1.55%
[0352] The results of this study demonstrate that cortisol levels
decreased in the presence of Formulation A in combination with
fragrance composition more than in the presence of solvent alone.
Therefore, the data demonstrated that the combination of
Formulation A and fragrance composition inhibited the increase of
salivary alpha-amylase under stress when smelled before application
of the stressor.
Example 15: Dose Response Data of Formulation A
[0353] In this Example, Formulation A from Example 1 was tested at
different amounts (based on drops) to determine the dose response
of percent change in a subject's salivary alpha-amylase and
salivary cortisol levels.
[0354] Methodology for number of drops. Ten to twenty-four
panelists age 30-45 participated in this study. The amount of
fragrance tested was divided equally and applied onto 6 blotter
cards each 3 by 5 inches in size. They were weighed and placed in
the test room 30 minutes before the stress test to equilibrate.
[0355] Stress was induced using a timed ten-minute
mathematical/word test in a small group competition setting. The
blotter cards were removed and weighed again after the stress test.
The difference in weight represented the weight loss in the 3,630
cubic feet test room.
[0356] Saliva was collected before (Pre) and immediately after
(Post) the stress test. Saliva samples were assayed for salivary
alpha-amylase using a commercially available kinetic reaction assay
kit and for salivary cortisol using a highly sensitive enzyme
immunoassay kit (Salimetrics.RTM., State College, Pa.).
[0357] The concentration of the formulation in the headspace was
determined. The concentration of the mixture in the headspace was
measured and the weight loss of the mixture at the end of the test
was calculated. The data summary is provided below.

Example 18: Consumer Products and Method For Determining
Concentrations
[0360] Formulation A, as shown in Examples 15-17, in the vapor
phase at 7.4 ng/ft.sup.3 to 27.7 ng/ft.sup.3 provides a reduction
of cortisol and alpha amylase markers. This indicates stress
reduction in a subject.
[0361] The concentration in shampoo and APDO soft solid product
that such accord should be added to arrive at a vapor phase of 7.4
ng/ft.sup.3 to 27.7 ng/ft.sup.3 is provided below. This procedure
can be used to determine the in product concentration required for
consumer products.
Estimation Method
[0362] The chassis-air partition coefficient can be measured for
materials in various chassis.
K i , chassis - air = C i , chassis C i , air ( 1 )
##EQU00001##
where:
[0363] K.sub.i,chassis-air is the chassis-air partition coefficient
for component i in the fragrance formula
[0364] C.sub.i,chassis is the concentration of component i in the
product formula chassis in molarity, M
[0365] C.sub.i,air is the concentration of component i in the
headspace air in equilibrium with the formula chassis in molarity,
M
[0366] For the "Example Accord" in the BC-162 shampoo chassis
components, the log chassis-air partition coefficients are as
listed in Table 11.
TABLE-US-00011 TABLE 11 Air Partition Coefficients logK, logK, APDO

[0367] The following is a conversion to get to units of molarity in
air:
C i , air .times. mol L = C i , air .times. ng ft 3 ( ft 3 28.317
.times. L ) ( 1 .times. g 10 9 .times. ng ) ( mol MW g ) ( 2 )
##EQU00002##
[0368] To determine the concentration in chassis, C.sub.i,chassis,
the following calculation is used:
C i , chassis .times. mol L = C i , air .times. mol L 10 logK ( 3 )
##EQU00003##
Weight percent in the chassis is determined by the following:
w i = C i , chassis .times. mol i L chassis MW i .times. g i mol i
.rho. chassis .times. g chassis mL chassis 1000 .times. mL L ( 4 )
##EQU00004##
where:
[0369] .rho..sub.chassis is the density of the chassis in g/mL
[0370] MW.sub.i is the molecular weight of component i
Weight percent of the individual components of the accord are
summed to generate the total weight percent to be used in the
chassis.
.times. ? = i .times. w i .times. .times. ? .times. indicates text
missing or illegible when filed ( 5 ) ##EQU00005##
Target weight percents for total Example Accord in product are as
shown in Table 12.
TABLE-US-00012 TABLE 12 Target Weight Percents Headspace, ng/cf 7.4
27.7 Chassis Low High Shampoo 0.000017% 0.000064% Soft Solid
Antiperspirant 0.000018% 0.000067%
The above numbers assume equilibrium headspace of the neat
product.
[0371] When a consumer product is used, often the touchpoint that
the consumer experiences will require a higher level in the product
such that when fragrance is lost through a wash process or diluted
in the surrounding air, the concentration is still within the
limits.
[0372] When in use conditions are considered, the calculated neat
product concentration should be increased by a factor of from about
three orders of magnitude to about five orders of magnitude.
[0373] Typically, when the in use concentration is a wet use (i.e.
wet fabric or hair) increasing the concentration in product by
three orders of magnitude over the calculated neat product
concentration should suffice. For non-wet applications (i.e.
deodorant, air care device) increasing the concentration in product
by five orders of magnitude over the calculated neat product
concentration should suffice.
[0374] For example, 0.015% of the Example Accord will deliver an
equilibrium wet fabric and/or hair headspace of approximately 0.024
ppb (equivalent to about 7.4 ng/cf) and 0.056% of the Example
Accord will deliver an equilibrium wet fabric and/or hair headspace
of approximately 0.09 ppb (equivalent to about 27.7 ng/cf).
[0375] In a soft solid Antiperspirant context as an example,
approximately 0.4% of the accord would be needed to ensure the
concentration of the Example Accord is at least 7.4 ng/cf when it
reaches the user's nose and approximately 1.5% of the accord would
be needed to ensure the concentration of the Example Accord is at
least 27.7 ng/cf when it reaches the user's nose.
[0376] Example Soft Solid Antiperspirant and Shampoo Formulas
containing the required levels of the Example Accord are found
