Description
FIELD OF THE INVENTION
[0001] The present invention relates to a hair colorant composition
essentially free of surfactant for use in combination with a
foaming dispenser with a specific perfume system.
BACKGROUND OF THE INVENTION
[0002] An outstanding issue with respect to hair colorants includes
ease of application and concerns over messy application resulting
in skin staining and uneven hair color results. Recent trends
indicate that consumers find handling of foamed products preferable
to gels, creams or liquids.
[0003] Foamed products are known to be generated in one of two
ways. The first being the use of a compressed gas (aerosols) which
are admixed with a composition that is evacuated from a container
by the consumer. A commercial example of this would be Kanebo
Cosmetics's Simpro hair colorant. GB2188257A discusses a device for
dispensing a two-component product, such as shampoos or dyes in a
pressurized container and dispensed in the form of foam.
[0004] Outstanding issues with pressurized systems such as these
examples are that oxidative hair colorants are radically initiated
reactions that require sequestration from oxygen or segregation of
the developer from the tint components (couplers, primaries, etc.)
until use of the hair colorant is desired by the consumer. The
sequestering packaging results in expensive, yet ineffective
packaging for dispensing the hair colorant due the lack of control
of the ratio of tint components to developer components coming out
of the pressurized system or ineffective in segregating the hair
colorant from oxygen.
[0005] The second way to generate a foam product is via a
non-pressurized dispenser in the form of a pump foamer or squeeze
foamer. A commercial example of a pump foamer would be Youngrace
Bubble Hair Color product. A commercial example of a squeeze foamer
would be Kao's Prettia Soft Foam Color, Liese Bubble Hair Color or
Blaune Foam Color products. See also US 2004/0213752A1. Further,
U.S. Pat. No. 7,040,507 discusses a foam-type hair dye apparatus
for converting a liquid hair dye into foam.
[0006] Pump foamers can be difficult to utilize with oxidative hair
colorant composition due to the use of metal parts, such as
springs, that are exposed to the oxidative hair colorant
composition. Due to the high pH of the dye composition
sub-component and presence of an oxidizing agent, the composition
reacts with metal parts of the pump mechanism, such as springs,
causing damage to the pump foamer and to the composition when
oxidized metal ions contaminate the composition.
Therefore, it is a desire to provide an hair colorant product
having a liquid hair colorant composition in a manually-actuable,
non-aerosol dispenser. Further, there exists a further desire to
minimize damage to hair when using hair coloring products while
producing good end color results.
[0007] It has been found that the reduction or elimination of
surfactants from the hair coloring composition can address the
outstanding needs of such products and provide further desired
benefits. However, a reduction of surfactants from the hair
colorant composition cause most perfumes to be insoluble or
unstable in the hair colorant compositions due to the hydrophobic
nature of perfumes (being essentially oils). Additionally, perfumes
may cause premature foam collapse than desired, leaving a liquid
rather than a foam in a user's hand. It has been found that careful
selection of perfume components via a ClogP criteria results in
perfumes that are soluble and stable in the hair colorant
composition which is essentially free of surfactants and do not
cause foam instability or premature collapse of the foam.
SUMMARY OF THE INVENTION
[0008] According to one aspect of the invention there is provided a
hair colorant product comprising an hair colorant composition
contained in a manually-actuable, non-aerosol dispenser, the
composition comprising a hair dye, an alkalizing agent, an
oxidizing agent, a foam stabilizing agent which is a member
selected from the group consisting of polymeric emulsifiers and
polymeric foam stabilizers and mixtures thereof and a perfume
comprising an Average ClogP less than 1.5, wherein the hair
colorant composition is substantially free of surfactant and when
dispensed from the manually-actuable, non-aerosol dispenser result
is a foam comprising a specific foam volume from about 6 to about
14 ml/g, preferably from about 7.5 ml/g to about 12 ml/g, more
preferably from about 8 to about 10.5 ml/g.

a hair colorant composition comprising: (i) a hair dye, (ii) an
alkalizing agent, (iii) an oxidizing agent, (iv) a foam stabilizing
agent which is a member selected from the group consisting of
polymeric emulsifiers and polymeric foam stabilizers and mixtures

1.5 to 2.5 and the balance of the perfume consists essentially of
perfume raw materials having a ClogP of less than 1.5, wherein the
hair colorant composition is substantially free of surfactant.
[0010] According to a further aspect of the invention there is

colorant composition the kit comprising: a tint composition
component comprising a hair dye, an alkalizing agent and a perfume;
wherein the perfume comprises an Average ClogP less than 1.5; a

preferably from about 7.5 ml/g to about 12 ml/g, more preferably
from about 8 to about 10.5 ml/g; wherein the tint composition
component and the developer composition component are essentially
free of surfactant.

DETAILED DESCRIPTION OF THE INVENTION
[0019] A reduction of surfactants in hair colorant compositions
used to produce a foamed product result in most perfumes being
insoluble or unstable in the hair colorant compositions due to the
hydrophobic nature of perfumes (being essentially oils).
Additionally, perfumes having a ClogP higher than desired may cause
inhibit or "kill" a foam, leaving a liquid rather than foam in a
user's hand. It has been found that careful selection of perfume
components via a ClogP criteria results in perfumes that are
soluble and stable in the hair colorant composition which is
essentially free of surfactants and do not cause foam instability
or premature collapse of the foam.
[0020] Surfactants are widely used in hair colorant compositions as
homogenizing agents and, in the case of foam hair colorants,
surfactants are used as foam stabilizing agents. When surfactants
are used in foam hair colorants, they may be present in an amount
of from 0.1% (1000 ppm) to 20% (200000 ppm) by weight of the
composition to be dispensed, typically exemplified in amounts of at
least 1.9% (19000 ppm) by weight.
[0021] It has been found that when surfactants are present in hair
colorant compositions and the compositions are subject to agitation
(e.g. vigorous shaking), foam forms in the reservoir of a dispenser
having head space. The formation of foam in the reservoir head
space leads to dispensing failure.
[0022] The hair colorant compositions of the invention do not
require the presence of a surfactant to create and maintain foam of
acceptable quality. While small amounts of surfactant may be
present as process aids, e.g. to assist homogenization of some
components, or a function other than foaming, it is preferred that
the compositions are substantially free of surfactant.
[0023] As used herein "substantially free of surfactant" means that
no anionic, cationic, zwitterionic or amphoteric surfactant is
purposefully added to the composition. In one embodiment, the
composition is substantially free of anionic, cationic,
zwitterionic, amphoteric and nonionic surfactants. Surfactants may
be present in trace amounts due to presence in components. By
"trace amounts" it is intended that the levels of surfactant are
less than 500 ppm, such as 0 ppm to 500 ppm. Preferably less than
200 ppm, such as between 0 ppm and 200 ppm. Preferably the levels
of surfactants are less than 100 ppm, such as between 0 ppm and 100
ppm. In general the compositions will contain less than 0.05% by
weight, preferably less than 0.02% by weight, more preferably less
than 0.01% by weight based on the hair colorant composition to be
dispensed.
[0024] With the reduction or elimination of surfactants from the
hair colorant composition, the stability of a perfume in the
compositions becomes difficult. As perfumes are essentially oils
and hydrophobic in nature, combining perfumes with aqueous based
systems essentially free of surfactants pose difficulties. One
difficulty identified is the inability to keep perfumes stable
within the hair colorant composition components when surfactant is
not present or significantly reduced. Another difficulty is that
the presence of a perfume can inhibit foam formation or "kills" a
foam.
[0025] It has been found that a perfume made of a multi-component
blend of perfume raw materials in which up to 30% by weight of the
perfume consists of essentially perfume raw materials having
individual average ClogP in the range 1.5 to 2.5 and the balance of
the perfume consists essentially of perfume raw materials having a
ClogP of less than 1.5 wherein the entire perfume composition has
an Average ClogP of less than 1.5, may be used as a fragrance in
the composition of the invention with causing rapid collapse of the
foam and which are able to be stably incorporated into the
composition. Preferred perfumes comprise a multi-component blend of
perfume raw materials each having a ClogP of up to 2.5, wherein the
entire perfume composition has an Average ClogP of less than 1.5.
It is most preferred that all of the perfume raw materials are
stable at a pH of from 9 to 11.
[0026] As used herein "Average ClogP" means that the ClogP of the
various perfume raw materials with the weight percentage, based
upon the weight of the entire perfume composition divided by 100
gives individual average ClogP for each component:
ClogP .times. wt % ( by weight of the perfume composition ) 100
##EQU00001##
and the sum of the individual average ClogP values gives the
Average ClogP.
[0027] It has been found that perfume raw materials not meeting the
criteria above being present at levels of 500 ppm in the perfume
composition cause instability of the perfume composition in the
hair colorant composition. Therefore, contaminates (as used herein
"contaminates" mean perfume raw materials having a ClogP above 4)
should be kept below 500 ppm in the perfume composition.
[0028] The logP values of many perfume ingredients are taken from
the ratio of the respective concentrations of a compound in the
octanol and water partitions of a two-phase system at equilibrium.
The concentration measurements are made at a constant temperature
of 25.degree. C. The "calculated logP" (ClogP) is determined by the
fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive
Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor
and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990). The
fragment approach is based on the chemical structure of each
perfume ingredient, and takes into account the numbers and types of
atoms, the atom connectivity, and chemical bonding. The ClogP
values, which are the most reliable and widely used estimates for
this physicochemical property, are preferably used instead of the
experimental logP values in the selection of perfume ingredients
which are useful in the present invention. There are existing
computational programs that can calculate ClogP values such as the
CSLogP-3.0 from ChemiSilico.
[0029] The perfume is generally incorporated in the hair colorant
compositions in an amount of from 0.05 to 5%, generally 0.1 to 2%,
for example 0.3 to 1% by weight of the composition to be dispensed.
In the case of a multi-part composition the perfume can be present
in one or more of the parts. In the case of a kit for an hair
colorant composition the perfume is preferably present in at least
the tint formulation component.

[0030] Other ingredients, whether conventionally used in hair
colorant compositions or not may be included if desired and not
adverse to the formation of foam in the essential absence of
surfactant (which may only be present in trace quantities as
indicate above). Hence evaluation of any additional ingredient
versus the overall composition functionality is needed and
exclusion of components resulting in premature foam collapse, such
as oily or greasy substances, is advisable.
[0031] It has been found that certain materials, which are not
surfactants, are capable of acting as foam stabilizing agents in
hair colorant compositions. As used herein "foam stabilizing
agents" include not only components that can help to stabilize the
liquid film of the foam bubbles, but components that may also
generate foam. Therefore foaming agents are included in the meaning
of foam stabilizing agents. These desired agents allow stable foams
of the hair colorant composition to be formed and maintained for
the desired timeframe.
Foam Formation and Stability
[0032] Foam consists of a dispersion of gas bubbles in a liquid.
Bubbles of gas rupture on contact with each other and additives are
needed to retard this contact. The bilayer films between two
bubbles in foam are fairly flat surfaces while the surfaces at
plateau borders where three bubbles meet are curved. There are
known chemical-physical properties which slow down or even stop the
film thinning process caused by drainage and stabilize the
foam.
Foam Stabilizing Agents
[0033] The foam stabilizing agents used in the compositions of the
invention are selected to provide foaming benefits and/or foam
stabilization benefits and are stable in the presence of an
oxidizing agent such as hydrogen peroxide or peroxymonocarbonate
ions or in the presence of alkaline pHs (such as that found in tint
compositions). Suitable foam stabilizing agents include polymeric
foam stabilizers and polymeric emulsifiers. The foaming stabilizing
agents of the present composition are essentially free of
surfactants traditionally used for foam formation and
stabilization. Combinations of polymeric emulsifiers and polymeric
foam stabilizers are also embodied herein.
Polymeric Foam Stabilizers
[0034] Polymeric foam stabilizing agents suitable for use herein
include cellulose materials such as methylcellulose (hydroxypropyl
methylcellulose sold as METHOCEL 40-101 and methylcellulose sold as
METHOCEL A4MP) and ethylcellulose (Cecetyl hydroxyethylcellulose
sold as NATROSOL PLUS).
[0035] The hydroxypropyl methylcellulose may have the general
structure of:
##STR00001##
[0036] The methylcellulose may have the general structure of:
##STR00002##
[0037] The "n" of these structures is selected to give the desired
viscosity. The METHOCEL 40-101 has a viscosity of about 75,000 mPa
s (for a 2% aqueous solution at 20.degree. C. with a Ubbelohde tube
viscometer) and the METHOCEL A4MP has a viscosity of about
4000-5000 mPa s (for a 2% aqueous solution at 20.degree. C. with a
Ubbelohde tube viscometer).
[0038] Another suitable foam stabilizing agent includes
(meth)acrylic polymers such as Acrylates/C.sub.10-30 alkyl acrylate
crosspolymer, a copolymer of C.sub.10-30 alkyl acrylates and one or
more monomers of acrylic acid, methacrylic acid or one of their
simple esters crosslinked with an allyl ether of sucrose or an
allyl ether of pentaerythritol. It is commercially available from
Goodrich as PEMULEN TR-1 and PEMULEN TR-2. PEMULEN TR-1 polymer is
preferred. CAPIGEL 98, an acrylates copolymer produced by
SEPPIC.
[0039] Another suitable foam stabilizing agent suitable for use
herein is a hydrophobically-modified alkali soluble emulsion
polymer synthesized through an emulsion polymerization process from
an acid/acrylate copolymer backbone and a monomer that connects the
hydrophobic groups as side chains. An example of such a material is
ACULYN.TM. 22, commercially available from Rohm Haas, which is
synthesized from acrylic acid, acrylate esters and a steareth-20
methacrylate ester with an INCI name of Acrylates/Steareth-20
Methacrylate Copolymer.
[0040] Another suitable foam stabilizing agent includes anionic
alkali-soluble polymer emulsion synthesized from acid and acrylate
co-monomers through emulsion polymerization. An example of such a
material is ACULYN.TM. 33, commercially available from Rohm Haas
with an INCI name of Acrylates Copolymer.
[0041] Mixtures of ACULYN.TM. 22 and ACULYN.TM. 33 may be used. One
embodiment utilizes a mixture of ACULYN.TM. 22 and ACULYN.TM. 33 in
a ratio (weight) of 5:1 to 1:5 weight ratio based upon the weight
of the composition or based upon the weight of the developer
composition. In one embodiment, a mixture of ACULYN.TM. 22 and
ACULYN.TM. 33 in a ratio (weight) of 1:3 to 1:4 by weight of the
developer composition is utilized. In one embodiment, a mixture of
ACULYN.TM. 22 and ACULYN.TM. 33 in a ratio (weight) of 4:1 to 1:1
by weight of the developer composition (containing the oxidising
agent) is utilized.
[0042] Polyquaternium-55, a polymer comprising vinyl pyrrolidone
(VP), dimethylaminopropyl methacrylamide (DMAPA) and
methacryoylaminopropyl lauryldimonium chloride (MAPLAC) is also
suitable for use herein and has the following generalized
structure:
##STR00003##
[0043] Polyquaternium-55 is sold under the tradename STYLEZE.RTM.
in a 10 and 20 variation. The n, m and p levels depend on the
monomer ratio. The STYLEZE.RTM.-10 has a monomer ratio of
0.85VP:0.11DMAPA:0.4MAPLAC. The STYLEZE.RTM.-20 has a monomer ratio
of 0.85VP:0.11DMAPA:0.4MAPLAC.
[0044] Another suitable foam stabilizing agent includes a
polyoxyethylene, polyoxypropylene block polymer that conforms
generally to the formula shown below in which the average values of
x, y and z are respectively 31, 54 and 31.
##STR00004##
sold under the tradename POLOXAMER 334.
[0045] Another suitable foam stabilizing agent includes a
polyethyleneoxide-polypropyleneoxide-polyethyleneoxide block
polymer terminating in primary hydroxyl groups sold under the
tradename PLURONIC P104 and PLURONIC F108 (ex. BASF).
Polymeric Emulsifiers
[0046] Suitable polymeric materials for use as a foam emulsifying
agent include polysaccharides, cellulosic materials, amine-bearing
polymers, acidic polymers obtainable from natural sources,
chemically modified starches, carboxyvinyl polymers,
polyvinylpyrrolidone, polyvinyl alcohol, polyacrylic acid polymers,
polymethacrylic acid polymers, polysiloxanes and mixtures
thereof.
[0047] Suitable polysaccharides include xanthan gum, carrageenin
gum, guar-guar, cationic guars, hydroxypropyl guar gum, agar-agar,
locust bean gum, alginates, tyloses, salts of any of these
materials (such as sodium salts) and mixtures thereof.
[0048] Suitable cellulosic materials include cellulose ethers, such
as carboxymethylcellulose, ethylcellulose, hydroxypropylcellulose,
methylcellulose, cellulose mixed ethers, such as
carboxymethylhydroxyethylcellulose, ethylhydroxyethylcellulose,
methoxyhydroxyalkylcelluloses, methylhydroxyalkylcelluloses, such
as methylhydroxyethylcellulose, methylhydroxypropylcellulose,
methylhydroxybutylcellulose; and mixtures of these.
[0049] Suitable amine-bearing polymers include deacytylated chitin,
sometimes known as chitosan, which as been modified to be soluble
in basic conditions usually by alkylation or by carboxymethylation,
but other modifications of chitin are also suitable. See Chitosan
Derivatives Obtained By Chemical Modifications For Biomedical And
Environmental Applications; International Journal of Biological
Macromolecules; Volume 43, Issue 5, 1 Dec. 2008, Pages 401-414.
[0050] Suitable polysiloxanes include dimethylpolysiloxanes,
methylphenylpolysiloxanes, cyclic silicones as well as silicone
compounds modified by amino, fatty acid, alcohol, polyether, epoxy,
fluoro, glycoside and or alkyl groups. Preferred as silicone
compounds according to the present invention are
polysiloxane-polyether copolymers aka dimethicone copolyol, which
are available from the company named Goldschmidt AG of Essen under
the trade name ABIL.RTM., especially polysiloxane-polyether
copolymers of the B 88 product family, such as ABIL.RTM. B 8843,
ABIL.RTM. B 8851, ABIL.RTM. B 8852, ABIL.RTM. B 8863, ABIL.RTM. B
88183 and ABIL.RTM. B 88184.
[0051] The foaming stabilizing agent is present in the oxidizing
hair colorant composition to be dispensed in an amount sufficient
to allow formation and/or stabilization of foam without need for a
surfactant. Thus, there is sufficient foam stabilizing agent
present to form and/or maintain foam when the composition is
substantially free of surfactant. Generally, the foam stabilizing
agent will be present in an amount of from 1 to 25% by weight,
preferably 2 to 15% by weight, more preferably 2 to 10% by weight
of the hair colorant composition. In the case of a multi-part kit,
the foam stabilizing agent may be present in one or more of the
components. Preferably, the foam stabilizing agent is present in
the component containing the oxidizing agent (developer) since a
single developer composition may be used with a plurality of
different hair dye (tint) formulations that form several different
hair shade colors. The foam stabilizing agent may be present in the
developer composition from 1 to 25% by weight, preferably 2 to 20%
by weight, preferably from 5% to 20% by weight of the developer
composition.
Foam
[0052] As used herein "foam" means a personal care composition
which after being passed through a manually-actuable, non-aerosol
dispenser has bubbles that sustain their shape and give a volume
independent of any type of container. It is preferably that the
volume is a foam specific volume from about 6 mL/g to about 14
mL/g, such as about 7.5 mL/g to about 12 mL/g, such as from about 8
mL/g to about 11 mL/g. One embodiment is a foam specific volume of
about 10 mL/g.
[0053] As used herein "stroke" means deflecting a reservoir that is
placed against a vertical flat surface, such as a wall, on the side
of the reservoir opposite the wall, 30 mm towards the wall at a
rate of 20 mm per second. "Squeeze" or "dispensed" are also
included in the term "stroke".
[0054] A manually-actuable, non-aerosol dispenser is optionally
designed to have a foam output per stroke or squeeze from about 0.5
gram/stroke to about 5.0 gram/stroke, preferably about 0.8
gram/stroke to about 4.0 gram/stroke, preferably from about 1.0
gram/stroke to about 4.0 gram/stroke. In one embodiment, the
manually-actuable, non-aerosol dispenser is optionally designed to
have a foam output per stroke or squeeze from about 1.8 gram/stroke
to about 2.2 gram/stroke.
[0055] A manually-actuable, non-aerosol dispenser is optionally
designed to have a foam output per stroke or squeeze from about 3
mL/stroke to about 70 mL/stoke, preferably from about 76 mL/stroke
to about 48 mL/stroke, preferably from about 8 mL/stroke to about
44 mL/stroke, preferably from about 18 mL/stroke to about 22
mL/stroke.
[0056] The minimum time for the foam to retain its volume is at
least long enough to transfer from a user's hand to the desired
location, such as on the hair, e.g. the foam substantially
maintains its shape and foam specific volume. A preferred minimum
time is for at least 10 seconds, for example at least 12, or at
least 15 seconds. It could be longer minimum time if a quantity of
foam, e.g. a bowl full by a hair dresser, is generated and
spreading on the head only starts once the bowl full is readily
made, such as 5 minutes or such as 10 minutes.
[0057] In order to fulfill the coloring action, hair colorant
compositions need to reach and disperse on the hair. Hence a foam
hair color composition needs to collapse within the time usually
allocated for hair coloring (e.g., 10 to 30 minutes). The collapse
of the foam could be as quickly as 3 to 10 minutes but may be up to
15 minutes, or up to 30 minutes.
The amount of sebum on hair can affect the foam and cause it to
collapse. The more sebum on the hair, the faster the foam collapses
on the hair.
Rheology Profile
[0058] The hair colorant composition has a desired rheological
profile during usage that ensures a desired user experience when in
contact with the hair colorant composition. The composition of the
present invention is subject to different stress/strain forces
during the consumer's use of the formulation. The formulation is
subject to mixing of two components together to form the desired
hair colorant composition, such as shaking of a container holding
the two components. The formulation is then foamed by passing it
through the foaming means, such as a squeeze foaming engine and is
dispensed into a user's hand. The formulation is then applied to
the desired surface, such as hair, and the foam collapses and forms
a liquid on the desired surface, such as hair. The desired
resulting viscosity of the hair colorant composition after the
collapse of the foamed hair colorant composition is selected such
that the composition does not drip or run from the surface on which
it is applied, such as hair on the head of a user.
[0059] As used herein "low shear viscosity" means a composition is
measured at a shear rate 0.01 s.sup.-1 according to the method
below. The low shear viscosity is believed to represent (1) the
viscosity of the composition as it sits in the reservoir and (2)
the viscosity of the composition "post-foam collapse". In other
words, the post-foam collapse is when the composition is foamed by
the dispenser and then the foam collapses. The low shear viscosity
in the rheology profile contributes to reducing the amount of foam
generated in the head space in the reservoir when the composition
is mixed or shaken by a user. Further, the low shear viscosity in
the rheology profile of the composition post-foam collapse is
important with respect to whether the composition stays on the
desired surface or if the composition runs or drips from the
surface after the foam collapses. The low shear viscosity of the
hair coloring composition is above 1000 mPa s (1000 cps),
preferably from about 1000 mPa s (1000 cps) to about 10,000 mPa s
(10,000 cps), preferably from about 2000 mPa s (2000 cps) to about
9000 mPa s (9000 cps), and preferably from about 2000 mPa s (2000
cps) to about 5000 mPa s (5000 cps).
[0060] As used herein "high shear viscosity" means a composition is
measured at a shear rate 500 s.sup.-1 according to the method
below. The high shear viscosity is believed to represent the
viscosity of the hair colorant composition moving from the
reservoir to the dispensing head orifice, usually through a foaming
means such as the mixing chamber. The high shear viscosity of the
hair colorant composition is less than 200 mPa s (200 cps),
preferably less than 100 mPa s (100 cps), preferably from about 1
mPa s (1 cps) to about 200 mPa s (200 cps).
Additional Hair Colorant Ingredients
Solvent
[0061] The hair colorant composition may comprise solvents such as
water, lower aliphatic alcohols, for example aliphatic alcohols
with from 1 to 4 carbon atoms such as ethanol, propanol and
isopropanol, or glycols such as glycerin and 1,2-propylene glycol.
The solvents may be utilized for the hair colorant composition or
in pre-composition components such as the tint composition or
developer composition in concentrations of from 0.1 to 30% by
weight.
Alkalizing Agent
[0062] The hair colorant composition, generally in a tint
composition, comprises an alkalizing agent, preferably a source of
ammonium ions or ammonia. Any alkalizing agent known in the art may
be used such as alkanolamides for example monoethanolamine,
diethanolamine, triethanolamine, monopropanolamine,
dipropanolamine, tripropanolamine,
2-amino-2-methyl-1,3-propanediol, 2-amino-2-methyl-1-propanol, and
2-amino-2-hydroxymethyl-1,3-propanediol, guanidium salts, and
alkali metal and ammonium hydroxides and carbonates, such as sodium
hydroxide and ammonium carbonate. Particularly, preferred
alkalizing agents are those which provide a source of ammonium
ions. Any source of ammonium ions is suitable for use herein.
Preferred sources include ammonium chloride, ammonium sulphate,
ammonium nitrate, ammonium phosphate, ammonium acetate, ammonium
carbonate, ammonium hydrogen carbonate, ammonium carbamate,
ammonium hydroxide, percarbonate salts, ammonia and mixtures
thereof. Particularly preferred are ammonium carbonate, ammonium
carbamate, ammonia and mixtures thereof. Suitable alkalizing agents
also include acidulents, such as inorganic and organic acids, e.g.,
phosphoric acid, acetic acid, ascorbic acid, citric acid or
tartaric acid, hydrochloric acid, and mixtures thereof.
[0063] The hair colorant composition or the tint composition may
comprise from about 0.1% to about 10% by weight, such as from about
0.5% to about 5%, such as from about 1% to about 3% of an
alkalizing agent, such as a source of ammonium ions.
Oxidizing Agent
[0064] The hair colorant compositions herein, generally in the
developer composition, may comprise at least one source of an
oxidizing agent. Preferred oxidizing agents for use herein are
water-soluble peroxygen oxidizing agents. "Water-soluble" as
defined herein means that in standard condition at least 0.1 g,
preferably 1 g, more preferably 10 g of said oxidizing agent can be
dissolved in 1 liter of deionized water. The oxidizing agents are
valuable for the initial solubilization and decolorization of the
melanin (bleaching) and accelerate the oxidation of the oxidative
dye precursors (oxidative dyeing) in the hair shaft.
[0065] The oxidizing agent may be selected from water-soluble
oxidizing agents which are inorganic peroxygen materials capable of
yielding hydrogen peroxide in an aqueous solution. The oxidizing
agents may be provided in aqueous solution or as a powder which is
dissolved prior to use. Water-soluble oxidizing agents include
hydrogen peroxide, inorganic alkali metal peroxides such as sodium
periodate and sodium peroxide and organic peroxides such as urea
peroxide, melamine peroxide, and inorganic perhydrate salt
bleaching compounds, such as the alkali metal salts of perborates,
percarbonates, perphosphates, persilicates, persulphates and the
like. These inorganic perhydrate salts may be incorporated as
monohydrates, tetrahydrates etc. Alkyl and aryl peroxides, and or
peroxidases may also be used. Mixtures of two or more such
oxidizing agents can also be used if desired. Preferred for use in
the compositions according to the present invention are hydrogen
peroxide, percarbonate, persulphates and combinations thereof.
[0066] The oxidative agent may comprise from about 0.1% to about
40% by weight, preferably from about 1% to about 30% by weight, and
most preferably from about 2% to about 30% by weight of the hair
colorant composition or developer composition. Another potential
oxidizing agent for use herein is a source of peroxymonocarbonate
ions. Preferably such a source is formed in situ from a source of
hydrogen peroxide and a hydrogen carbonate ion source. Such an
oxidizing agent has been found to be particularly effective at a pH
(of the hair care composition) of up to and including 9.5,
preferably 7.5 to 9.5 more preferably about pH 9. Moreover, this
system is also particularly effective in combination with a source
of ammonia or ammonium ions. It has been found that this oxidizing
agent can deliver improvements to the desired hair color results
particularly with regard to the delivery of high lift, whilst
considerably reducing the odor, skin and scalp irritation and
damage to the hair fibers.
[0067] Accordingly, any source of these peroxymonocarbonate ions
may be utilized. Suitable sources for use herein include sodium,
potassium, guanidine, arginine, lithium, calcium, magnesium,
barium, ammonium salts of carbonate, carbamate and hydrocarbonate
ions and mixtures thereof such as sodium carbonate, sodium hydrogen
carbonate, potassium carbonate, potassium hydrogen carbonate,
guanidine carbonate, guanidine hydrogen carbonate, lithium
carbonate, calcium carbonate, magnesium carbonate, barium
carbonate, ammonium carbonate, ammonium hydrogen carbonate and
mixtures thereof. Percarbonate salts may also be utilized to
provide both the source of carbonate ions and as an oxidizing
agent. Preferred sources of carbonate ions, carbamate and
hydrocarbonate ions are sodium hydrogen carbonate, potassium
hydrogen carbonate, ammonium carbamate, and mixtures thereof.
[0068] The oxidative agent may comprise from about 0.1% to about
15% by weight, preferably from about 1% to about 10% by weight, and
most preferably from about 1% to about 8% by weight of a
hydrogencarbonate ion and from about 0.1% to about 10% by weight,
preferably from about 1% to about 7% by weight, and most preferably
from about 2% to about 5% by weight of the oxidative agent of a
source of hydrogen peroxide.
pH
[0069] The hair colorant compositions of the present invention may
have a pH of from 8 to 12, preferably from 8 to 10. For embodiments
comprising a peroxymoncarbonate ion, the pH is preferably up to and
including pH 9.5, more preferably from about 9.5 to about 7.5, even
more preferably from about 9.5 to about 8.4, most preferably from
about 9.4 to about 8.5, and even more preferably about pH 9.3 or
9.0.
[0070] Any sub-components of the hair colorant compositions, such
as a tint composition or a developer composition may have a
different pH from the hair colorant composition. For example, if
the tint composition comprises an alkalizing agent, the tint
composition will have an alkaline pH, such as higher than 8.
[0071] The pH of the compositions can be determined by using either
a Mettler Toledo MP220 or a MP225 pH equipment, fitted with a
standard laboratory pH electrode. The equipment is calibrated
before each use using standard calibration buffers and using the
standard calibration procedure.
Hair Dye
[0072] The hair colorant composition contains a hair dye which may
be selected from those known in the art, e.g. oxidative dye
precursors, through which the coloring is produced by the action of
oxidizing agents, such as for example hydrogen peroxide, or in the
presence of atmospheric oxygen (if necessary with the addition of a
suitable enzyme system). The hair dye may be a oxidative dye
precursor, a direct dye or a mixture thereof.
Oxidative Dye Precursors
[0073] The hair care compositions or a sub-component thereof (tint
composition) may include oxidative dye precursor in the form of
primary intermediates or couplers. The compounds suitable for use
in the hair colorant compositions (including those optionally
added), in so far as they are bases, may be used as free bases or
in the form of their physiologically compatible salts with organic
or inorganic acids, such as hydrochloric, hydrobromic, citric,
acetic, lactic, succinic, tartaric, or sulfuric acids, or, in so
far as they have aromatic hydroxyl groups, in the form of their
salts with bases, such as alkali phenolates.
These compounds are well known in the art, and include aromatic
diamines, aminophenols, aromatic diols and their derivatives (a
representative but not exhaustive list of oxidation dye precursor
can be found in Sagarin, "Cosmetic Science and Technology",
"Interscience, Special Edn. Vol. 2 pages 308 to 310). It is to be

[0076] The hair colorant compositions or sub-components thereof
(such as a tint composition or developer composition) comprise a
carboxylic acid chelant, a phosphonic acid chelant, a
polyphosphoric acid chelant, salts thereof, or mixtures thereof.
Suitable chelants include diethylenetriamine pentaacetic acid

chelant, salts thereof, derivatives thereof, or mixtures
thereof.
Radical Scavenger
[0078] The hair colorant compositions, preferably the tint
compositions, may further comprise a source of radical scavenger.
As used herein the term radical scavenger refers to a species that
can react with a carbonate radical to convert the carbonate radical
by a series of fast reactions to a less reactive species, i.e. a
carbonate radical scavenger.
[0079] Suitable radical scavengers for use herein may be selected
from the classes of alkanolamines, amino sugars, amino acids,
esters of amino acids and mixtures thereof. Particularly preferred
compounds are: monoethanolamine, 3-amino-1-propanol,
4-amino-1-butanol, 5-amino-1-pentanol, 1-amino-2-propanol,
1-amino-2-butanol, 1-amino-2-pentanol, 1-amino-3-pentanol,

N-acetylglucosamine, glycine, arginine, lysine, proline, glutamine,
histidine, sarcosine, serine, glutamic acid, tryptophan, and
mixtures thereof, and the salts such as the potassium, sodium and
ammonium salts thereof and mixtures thereof. Especially preferred
compounds are glycine, sarcosine, lysine, serine, 2
methoxyethylamine, glucosamine, glutamic acid, morpholine,
piperidine, ethylamine, 3 amino-1-propanol and mixtures

about 0.1% to about 10% by weight, preferably from about 1% to
about 7% by weight of the hair colorant composition or the tint
composition of a radical scavenger.
[0081] Preferably, the radical scavenger is present at an amount
such that the weight ratio of radical scavenger to carbonate ion is
from 2:1 to 1:4. The radical scavenger is also preferably selected
such that it is not an identical species as the alkalizing
agent.
Conditioning Agent
[0082] The hair colorant composition may comprise a conditioning
agent although the conditioning agent would need to be carefully
selected to not inhibit foam formation or stabilization, including
premature foam collapse. Optionally, a separate conditioning
composition comprising a conditioning agent may be used with the
hair colorant product.
[0083] Conditioning agents suitable are selected from silicone
materials, amino silicones, fatty alcohols, polymeric resins,
polyol carboxylic acid esters, cationic polymers and mixtures
thereof. Additional materials include glycerin and sorbitol.
Particularly useful conditioning materials are cationic polymers.
Conditioners of cationic polymer type can be chosen from those
comprising units of at least one amine group chosen from primary,
secondary, tertiary and quaternary amine groups that may either
form part of the main polymer chain, or be borne by a side
substituent that is directly attached to the main polymer
chain.
[0084] Silicones can be selected from polyalkylsiloxane oils,
linear polydimethylsiloxane oils containing trimethylsilyl or
hydroxydimethylsiloxane endgroups, polymethylphenylsiloxane,
polydimethylphenylsiloxane or polydimethyldiphenylsiloxane oils,
silicone resins, organofunctional siloxanes having in their general
structure one or a number of organofunctional group(s), the same or
different, attached directly to the siloxane chain or mixtures
thereof. Said organofunctional group(s) are selected from:
polyethyleneoxy and/or polypropyleneoxy groups, (per)fluorinated
groups, thiol groups, substituted or unsubstituted amino groups,
carboxylate groups, hydroxylated groups, alkoxylated groups,
quaternium ammonium groups, amphoteric and betaine groups. The
silicone can either be used as a neat fluid or in the form of a
pre-formed emulsion.
[0085] The conditioning agent may be used at levels of from about
0.05% to about 20% by weight of the conditioning composition, such
as from about 0.1% to about 15%, such as of from about 0.2% to
about 10%, such as from about 0.2% to about 2% by weight of the
conditioning composition. If utilized in the hair colorant
composition itself, the conditioning agent may be used from about
0.05% to about 5% by weight of the hair colorant composition.
Other Optional Ingredients
[0086] Other ingredients, whether conventionally used in hair
colorant compositions or not, may be included if desired and are
not adverse to the formation of foam in composition including
compositions essential free of surfactant. Hence evaluation of any
additional ingredient versus the overall composition functionality
is needed and exclusion of components resulting in premature foam
collapse, such as oily or greasy substances, is advisable.
Hair Colorant Composition Product
[0087] In one embodiment, the present application relates to a hair
colorant composition product comprising a manually-actuable,
non-aerosol dispenser equipped with a reservoir comprising a
reservoir volume, a mixing chamber and a dispensing head. The
reservoir may contain an hair colorant composition and when the
manually-actuable, non-aerosol dispenser is actuated, the hair
colorant composition is mixed with air in a liquid to air ratio of
from about 1:6 to about 1:15 and the hair colorant composition is
dispensed as a foam.
[0088] Manually-actuable, non-aerosol dispensers for foam
generation are well known in the art. These foam dispensers
comprise a reservoir for holding a liquid to be dispensed in the
form of foam with an assembly which can be mounted on or in an
opening of the reservoir. The assembly comprises a dip tube which
extends into the reservoir and then into a mixing chamber, a liquid
pump for pumping the liquid from the reservoir and an air pump to
mix air with the liquid in the mixing chamber in order to form
foam. The foam is dispensed out of the mixing chamber and through a
dispensing channel out of a dispensing head comprising a dispensing
orifice. In the dispensing channel one or more porous elements such
as sieves or screens that may be arranged to form homogeneous
foam.
[0089] The amount of work required for dispensing the hair colorant
composition with the rheology profiles described herein is unique
verses known hair colorant compositions. It is unique in that with
known hair colorant compositions, more work is expended moving air
than the liquid in such systems. For the hair colorant compositions
of the present invention having specific rheology profiles, more
work is expended to move the liquid than the air in such systems.
The dispensing of the hair colorant composition can be carried out
by squeezing an exterior of the reservoir of the manually-actuable,
non-aerosol dispenser. Consistent therewith, the foam can be
dispensed through the dispensing head orifice of the dispensing
head.
[0090] The use of hair colorant compositions with the desired
rheology profile and the amount of work required to move the hair
colorant composition further poses unique problems relating the
amount of shear generated in the manually-actuable, non-aerosol
dispensers suitable for use herein. The use of hair colorant
compositions with the desired rheology profile further affects the
ratio of air to liquid. The amount of work, shear generation and
air to liquid ratio are aspects that can be attributed to the
manually-actuable, non-aerosol dispenser structure.
[0091] The ratio of air to liquid is from about 1:6 to about 1:15,
preferably from about 1:8 to about 1:12, preferably 1:10.
[0092] Suitable manually-actuable, non-aerosol dispenser structure
include the dimensions of the dip tube, dimensions of the air
ingress into the mixing chamber, mixing chamber dimensions,
including the ingress and egress orifices from the mixing chamber,
dispensing channel dimensions, porous elements (such as screens or
meshes) and dispensing head orifice.
[0093] The manually-actuable, non-aerosol dispenser may be
exemplified by the following patents: U.S. Pat. No. 3,709,437; U.S.
Pat. No. 3,937,364; U.S. Pat. No. 4,022,351; U.S. Pat. No.
4,147,306; U.S. Pat. No. 4,184,615; U.S. Pat. No. 4,615,467; and FR
2,604,622. One particular example of a squeeze foamer useful herein
is a squeeze foamer that is able to dispense from an upright or
inverted position such as the one discussed in U.S. Pat. No.
6,604,693 assigned to Taplast, and more specifically, at column 2,
line 65, through column 4, line 67 of that patent.
[0094] The manually-actuable, non-aerosol dispenser may comprise a
reservoir. The reservoir comprises a volume such that the reservoir
volume is larger that the volume of the hair colorant composition
contained within the reservoir. The area of the reservoir that is
not occupied by the hair colorant composition is the head space.
The head space should remain relatively free of the hair colorant
composition or bubbles of the hair colorant composition. If the
reservoir is shaken or inverted while the hair colorant composition
is contained therein, the head space should remain relatively free
of the hair colorant composition or bubbles. As used herein,
"relatively free" means less than 50%, such as less than 75%, such
as less than 90%, such as 75% to 100% of the head space contains
the hair colorant composition or bubbles.
[0095] The reservoir is selected to have enough volume to contain
the hair colorant composition, any mechanism for foaming the hair
colorant composition and head space. The reservoir volume in one
embodiment is selected to be from about 100 ml to about 500 ml,
from about 150 ml to about 400 ml, such as 250 ml. The ratio of the
reservoir volume to hair colorant composition volume is from about
1:0.30 (30% full) to about 1:0.70 (70% full), such as from about
1:0.40 (40% full) to about 1:0.55 (55% full) (i.e., the reservoir
volume is larger than the hair colorant composition volume).
[0096] The shape of the reservoir may be selected such that when
the hair colorant composition is contained within the reservoir,
the force required per volume displacement may be optimized. In one
embodiment, the force required per volume displacement is optimized
when the shape of the bottle is selected to have an elliptical
cross-section as viewed from vertical axis of the bottle (from the
top or bottom of the bottle). The elliptical cross-section is
preferably concentric such that a neck suitable for a threaded or
snap-on cap may be used to close the reservoir. The major axis of
the elliptical cross-section is orientated such that it is
perpendicular to the force applied to the reservoir surface
[0097] FIG. 1 illustrates a general structure for a personal care
composition product (25) comprising a foamer assembly (1) and a
reservoir (3).
[0098] The reservoir (3) having a reservoir volume (27) that
contains the personal care composition is fluidly connected to the
mixing chamber (5) such that the personal care composition is
transported from the reservoir (3) when the manually-actuable,
non-aerosol dispenser (25) is dispensed (e.g., "stroke"). The fluid
connection is a dip tube (7). The dip tube (7) diameter for the
present personal care composition having a relatively higher
viscosity requires a relatively larger diameter in order to allow
for easy dispensing (low amount of force needed to dispense) and to
achieve the desired foam specific volume.
[0099] The dip tube (7) diameter is preferably selected to have a
diameter of greater than 2.0 mm, preferably from about 2.0 mm to
about 5.0 mm, more preferably from about 2.5 mm to about 4.0 mm.
The viscosity of the liquid with a dip tube (7) diameter between
about 2.0 mm and about 4.0 mm allows for the liquid to be conveyed
from the reservoir (3) into the mixing chamber (5) with lower
amounts of force by the user during dispensing (e.g., "stroke")
while achieving the desired foam density discussed herein.
[0100] The mixing chamber (5) comprises at least one air ingress
orifice (9), at least one liquid ingress orifice (11) and at least
one mixing chamber egress orifice (13). The mixing chamber (5)
further comprises an internal volume and an exterior wall, which
defines the internal volume of the mixing chamber (5). The mixing
chamber (5) allows for the combination of the personal care
composition and air to begin the formation of the foamed personal
care composition. Modification of the various orifice (9, 11, 13)
areas (the two-dimentions of the indicating orifices that comprise
part of the mixing chamber (5) exterior wall) can affect the foam
specific density, particularly the correlation of the air ingress
orifice (9) and the liquid ingress orifice (11) such that the
liquid to air ratio is appropriate.
[0101] The air ingress orifice (9) is suitable to convey air that
has entered into the headspace of the reservoir (3). The mixing
chamber (5) may comprise more than one air ingress orifice (9). In
one embodiment, the mixing chamber (5) comprises one air ingress
orifice (9). The area of the air ingress orifice (9) may be from
about 0.62 mm.sup.2 (about a 0.2 mm diameter circular air ingress
orifice) to about 3.14 mm.sup.2 (about a 1 mm diameter circular air
ingress orifice), preferably from about 1.26 mm.sup.2 (about a 0.4
mm diameter circular air ingress orifice) to about 1.88 mm.sup.2
(about a 0.8 mm diameter circular air ingress orifice). If more
than one air ingress orifice (9) is selected, the total area of all
air ingress orifices (9) should be used. Communication of the air
in to the mixing chamber (5) via the air ingress orifice (9) can be
and indirect communication with the mixing chamber (5) or a direct
communication with the mixing chamber (5).
[0102] Similarly, the liquid ingress orifice (11) is suitable to
fluidly convey the personal care composition into the mixing
chamber (5) from the reservoir (3), preferably via a dip tube (7).
In one embodiment, the mixing chamber (5) comprises more than one
liquid ingress orifice (11). In one embodiment, the mixing chamber
(5) comprises three liquid ingress orifices (11). The area of the
liquid ingress orifice (11) should be from about 1.5 mm.sup.2 to
about 3 mm.sup.2. In one embodiment the liquid ingress orifice (11)
should be from about 1.8 mm.sup.2 to about 2.3 mm.sup.2. If more
than one liquid ingress orifice (9) is selected, the total area of
all air ingress orifices (9) should be used. For example, a total
area of 2.0 mm.sup.2 for three liquid ingress orifices (11) would
equate the total areas of all three liquid ingress orifices (11)
combined. The fluid conveyance from the reservoir (3) to the mixing
chamber (5) may be an indirect communication pathway with the
mixing chamber (5) or a direct communication pathway with the
mixing chamber (5).
[0103] As used herein "indirect communication" means that the
conveyance of the air or personal care composition to the mixing
chamber (5) travels along a pathway through some other physical
structure before entering into the mixing chamber (5). For example,
the air or personal care composition will come into contact with
the exterior wall of the mixing chamber (5) before entering into
the mixing chamber (5) through the respective orifice (9, 11). In
one embodiment, a void volume (30) is contiguous with the exterior
wall of the mixing chamber (5). The air or the personal care
composition is conveyed from the reservoir, through the dip tube
(7) into the void volume (30) external to the mixing chamber (5).
The void volume (30) is in air and/or in liquid communication with
the air ingress orifice (9) and/or the liquid ingress orifice (11),
respectively.
[0104] As used herein "direct communication" means that the
conveyance of the air or personal care composition to the mixing
chamber (5) travels directly into the mixing chamber (5). For
example, the air or personal care composition will come into
contact with the internal volume of the mixing chamber (5) through
the respective orifice (9, 11) without contacting a component
exterior to the mixing chamber (5).
[0105] In one embodiment, the mixing chamber egress orifice (13) is
selected to create an increase in pressure within the mixing
chamber (5). The mixing chamber (5) may comprise more than one
mixing chamber orifice (13). In one embodiment, the mixing chamber
(5) comprises one mixing chamber egress orifice (13).
[0106] The mixing chamber (5) has an outer wall creating an
internal volume of the mixing chamber (5). The top edge of the
outer wall defines a circumference. The mixing chamber egress
orifice (13) may be the same size area of the circumference of the
mixing chamber (5) top edge, but preferably is selected to be
smaller area than the area of the circumference of the mixing
chamber (5) top edge so as to create an increase in pressure in the
mixing chamber (5). The area of the mixing chamber egress orifice
(13) may be between about 0.314 mm.sup.2 (0.1 mm diameter circular
orifice) to about 9.42 mm.sup.2 (3 mm diameter circular orifice).
In one embodiment, the mixing chamber egress orifice (13) comprises
an area of about 2.512 mm.sup.2 (0.8 mm diameter circular orifice)
to about 5.652 mm.sup.2 (1.8 mm diameter circular orifice). If more
than one mixing chamber egress orifice (13) is present, the total
area of all of the mixing chamber egress orifices should be
considered.
[0107] In an embodiment, a diffuser plate (29) comprises the mixing
chamber egress orifice (13). The diffuser plate (29) may be part of
the mixing chamber (5) structure or it may be a separate component
that fits into the mixing chamber (5). It is believed that the
diffuser plate (29) helps increase the residence time in the mixing
chamber (5) and subjects the personal care composition to more time
in the shear generated in the mixing chamber (5).
[0108] The mixing chamber (5) is fluidly connected to the foamer
assembly (1). The personal care composition enters into the mixing
chamber (5) via the liquid ingress orifice (11) and mixes with air
which enters the mixing chamber (5) via the air ingress orifice
(9).
[0109] The air is ordinarily supplied from the environment exterior
to the manually-actuable, non-aerosol dispenser (25), the air
entering the manually-actuable, non-aerosol dispenser (25) after a
stroke which is then located in the headspace of the reservoir (3).
The controlled entry or exit of air into the manually-actuable,
non-aerosol dispenser (25) reservoir (3) headspace may be
accomplished by a ball valve (23) or silicone seal or gasket. The
ball valve or silicone seal or gasket may be located in the foamer
assembly (1) an in communication with the headspace. In one
embodiment, the ball valve (23, silicone seal or gasket is located
to communicate between the reservoir (3) and the air external to
the manually-actuable, non-aerosol dispenser (25) such that when
the manually-actuable, non-aerosol dispenser (25) is being
dispensed, the ball valve (23) silicone seal or gasket excludes
entry of air external to the manually-actuable, non-aerosol
dispenser (25) into the reservoir (3) headspace so that the air in
the headspace is conveyed to the mixing chamber through the air
ingress orifice (9). After dispensing ("stroke"), the ball valve
(23), silicone seal or gasket allows entry of air external to
manually-actuable, non-aerosol dispenser (25) to enter into the
reservoir (3) to refill the headspace for the next stroke.
[0110] After the personal care composition and air enter into the
mixing chamber (5) and form the foamed personal care composition,
the foamed personal care composition exits the mixing chamber (5)
via the mixing chamber egress orifice (13), traveling through a
foam fluid connection (17) to the foamer assembly (1) and exits the
foamer dispensing orifice (19). The foam fluid connection (17)
between the mixing chamber egress orifice (13) and the foamer
dispensing orifice (19) may have present therein one or more
screens or meshes (21a, 21b, 21c) which may be used to modify the
foam specific volume. The number of meshes, the size of the
openings in the meshes and the frequency of the openings in the
meshes may be used to modify the foam specific volume. In one
embodiment, at least 2 meshes (21a, 21b) are utilized, wherein the
2 meshes (21a, 21b) are contiguous with each other. The meshes
comprise a diameter section and a depth. The diameter section
(largest surface area of the mesh) is the portion of the mesh which
would be contiguous with another mesh.
[0111] At least a lower portion of the dip tube (7) may be angled
toward a lowermost front corner of the reservoir (3) when the
reservoir (3) is tilted at an angle for optimal squeezing and
dispensing of foam, so as to maximize efficient use of the personal
care composition in the reservoir (3). The angle of incline of the
lowermost portion of the dip tube (7) preferably mimics the angle
of incline of the foamer dispensing orifice (19), and both are
preferably at an angle downward from a horizontal axis through the
mesh closest to the dispensing head orifice (19) in a range of
about 30.degree. to about 45.degree..
[0112] In one embodiment, one to three meshes are present in the
fluid connection between the mixing chamber egress and the
dispensing head orifice. In one embodiment, two meshes (21a, 21b)
are located in the foam fluid connection (17) in close proximity to
the mixing chamber egress orifice (13), wherein the two meshes
(21a, 21b) comprise about 170 micron (.mu.) opening size and
wherein one mesh (21c) is located in close proximity to the foamer
dispensing orifice (19), wherein the one mesh (21c) comprises about
a 70 micron (.mu.) opening size.
[0113] In one embodiment two meshes (21a, 21b) located in the foam
fluid connection (17) in close proximity to the mixing chamber
egress orifice (13) and the two meshes (21a, 21b) are contiguous
with each other, wherein the two meshes (21a, 21b) comprise about
170 micron (.mu.) opening size and wherein one mesh (21c) is
located in close proximity to the foamer dispensing orifice (19),
wherein the one mesh (21c) comprises about a 70 micron (.mu.)
opening size. Each mesh is preferably provided as an injection
molded wafer or disc having a cylindrical sidewall and a screen
extending across one end of the cylindrical sidewall. The screen
does not extend axially (from the top edge of the cylindrical
sidewall to the bottom edge of the cylindrical sidewall moving
along the y-axis) the entire length of the cylindrical sidewall. As
used in this paragraph, "contiguous" means that the two cylindrical
sidewalls of the respective wafers or discs are immediately
adjacent one another. However, each of the respective wafers is
preferably oriented with its screen is facing up, such that even
with the two wafers or discs in contact with one another, there is
a gap separating the screen of the first disc from the screen of
the second disc.
[0114] Turning now to FIG. 3, a particularly preferred embodiment
is illustrated in which only two meshes (21a, 21c) are utilized,
one (21a) in close proximity to the mixing chamber egress orifice
(13) and the other (21c) disposed close proximity to the foamer
dispensing orifice (19).
[0115] By varying the size of the mixing chamber egress orifice
(13), the number of meshes (21a, 21b, 21c), and the opening size of
the screens of the meshes, it is possible to reduce the amount of
work required to expel a desired quantity of foam, while
substantially preserving the desired foam specific volume. For
instance, in an exemplary implementation of the embodiment
illustrated in FIG. 1, a mixing chamber egress orifice (13) of 1 mm
diameter is provided in a diffuser plate (29) [area of orifice is
pi*diameter]. In that embodiment, three mesh wafers or discs are
provided in the foam fluid connection (17), with each of the first
two (21a, 21b) comprising a mesh opening size of about 170 micron
(.mu.), and the third comprising a mesh opening size of about 70
micron (.mu.).
[0116] In an exemplary implementation of the embodiment illustrated
in FIG. 3, the second mesh (21b) is omitted, the mixing chamber
egress orifice is increased to 1.75 mm in a diffuser plate (29)
[area of orifice is pi*diameter], the first mesh (21a) has a mesh
opening size of about 170 micron (.mu.), and the mesh wafer or disc
(21c) comprises a mesh opening size of about 70 micron (.mu.) in
located in the foam fluid connection (17).
Kits
[0117] The hair colorant composition products may be sold as a kit
containing a tint composition component and a developer composition
component that are packaged with gloves and instructions.
Optionally a conditioning composition component and/or a color
refresher composition may also included. A user will combine the
tint composition component and developer composition component and
then apply the mixed composition in the form of foam to hair.
[0118] The tint composition component of the present application
may contain at least one hair dye that is selected from oxidative
dye precursors, couplers and direct dyes. Additional materials
included in the tint composition component include an alkalizing
agent, perfume with an Average ClogP of less than 1.5, solvent,
radical scavengers and foam stabilizing agents. The tint
composition is substantially free of surfactant.
[0119] The developer composition component of the present
application may contain a solvent, an oxidizing agent and foam
stabilizing agents. The developer composition component is
substantially free of surfactant.
[0120] Generally, the weight ratio of tint formulation:developer
formulation is in the range 5:1 to 1:5, such as 1:1, 1:1.5, 1:2,
1:3 and 1.4 depending on strength of developer composition and tint
composition.
[0121] Included in the kit of the present application is
manually-actuable, non-aerosol dispenser. The dispenser is capable
of dispending the mixture of the tint composition component and
developer composition component in a foam comprising a specific
foam volume from about 6 ml/g to about 14 ml/g, preferably from
about 7.5 ml/g to about 12 ml/g, more preferably from about 8 ml/g
to about 10.5 ml/g.
[0122] The kit may contain two or more containers. In one
embodiment, the tint composition component is contained in one
container and the developer composition component is contained in
the manually-actuable, non-aerosol dispenser or reservoir of the
manually-actuable, non-aerosol dispenser.
[0123] Optional components for the kit include a conditioner
composition and a refreshing color composition. The conditioner
composition may comprise a conditioning agent. The refreshing color
composition may comprise a conditioning agent and direct dyes.
Method of Use
[0124] A user mixes a tint composition and a developer composition
together in the reservoir of the manually-actuable, non-aerosol
dispenser immediately before use. The user may then shake to mix
the tint composition and developer composition. Shaking may be in a
vertically reciprocating motion or in a rotating reciprocating
shaking motion for a minimum of 10 seconds to mix the tint
composition and developer composition. The user then actuates the
manually-actuable, non-aerosol dispenser to dispense foam (foamed
hair colorant composition) either into the user's gloved hand or
directly onto the hair. The foam may begin to collapses between
about 10 seconds to 30 minutes after being dispensed. The
exemplified compositions given in the tables 7 and 8 hereinafter
illustrate suitable compositions.
[0125] After allowing the collapsed foam (now a liquid composition)
to remain on the hair for 5 to 30 minutes (to ensure uniform
application to all of the hair), the user then rinses his/her hair
thoroughly with water and allows it to dry.
[0126] When present, the optional conditioning agent can be
provided in another container. In one embodiment, the content of
the conditioner container can be applied (after an optional rinse
step) as a post-treatment immediately after the hair colorant
composition.
[0127] According to the present invention, the methods of coloring
hair also comprise embodiments whereby the foamed hair colorant
composition of the present invention is applied to the hair and
preferably the mixture is worked into the hair by a user's fingers
or a comb or similar implement for a few minutes (to ensure uniform
application to all of the hair). The composition is then allowed to
remain on the hair in order for the color to develop for a time
period of less than about 20 minutes, preferably less than about 15
minutes, more preferably from about 5 minutes to about 10 minutes,
most preferably for about 10 minutes. The user then rinses his/her
hair thoroughly with tap water and allows it to dry and or styles
the hair as usual.
[0128] According to a further alternative embodiment of the present
invention, the method of coloring the hair is a sequential hair
coloring method comprising the steps of at least two sequential
hair color treatments wherein the time period between each
treatment is from 1 to 60 days, preferably from 1 to 40 days, more
preferably from 1 to 28 days, even more preferably from 1 to 14
days and most preferably from 1 to 7 days. In such embodiments, the
time that the composition is retained on head may be less than
about 20 minutes and is preferably less than about 10 minutes and
most preferably from about 2 minutes to about 5 minutes.
Test Methods
Viscosity
Sample Preparation
[0129] The tint composition and developer composition are combined
to make an hair colorant composition. The sample preparation of the
hair colorant composition should be as follows: [0130] 1. combine,
in a 1:1 weight ratio the tint composition and the developer
composition in a container from which it can be dispensed. The
container should be closed or capped. [0131] 2. the closed
container is then shaken for 15 seconds. [0132] 3. The contents of
the closed container poured into a 100 tall container available
from FlackTek Inc. is then placed onto a DAC 800 FVZ SpeedMixer
from FlackTek Inc. set to 1950 rpm for 10 seconds to draw any
bubbles in the out of the sample. [0133] 4. Any bubbles or foam on
the top of the liquid is decanted. [0134] 5. The sample is then
measured for viscosity.
Low Shear Viscosity and High Shear Viscosity
[0135] The low-shear viscosity and the high shear viscosity, as
defined above, is measured via a TA Instruments AR2000 Rheometer
having the following geometry: [0136] 40 mm 2.degree. stainless
steel cone [0137] 40 mm stainless steel plate [0138] Standard Size
DIN or Conical Concentric Cylinders Using the data analysis program
of the TA Instruments AR2000 Rheometer, collected data is then
graphed and a point at the beginning of the run is recorded as the
low-shear viscosity. Data should be run at least twice to ensure
correlation of the recorded data.
[0139] The low shear viscosity is measured at 0.01 s.sup.-1 and the
high shear viscosity is measured at 500 s.sup.-1.
Foam Specific Volume
[0140] Foam specific volume is measured by placing a 100 ml beaker
onto a mass balance, tarring the mass of the beaker and then
dispensing from a foaming dispenser into the 100 ml beaker until
the volume of the foam is equal to 100 ml. Record the resulting
mass of the 100 ml of foam at 5 seconds from the end of dispensing.
Dividing the volume (100) by the mass of the foam results in the
foam specific volume having the units of mL/g.

[0143] Each tint formulation may be admixed with the developer
formulation to provide a hair colorant composition. The weight
ratio of tint formulation to developer formulation may be varied
depending upon the precise shade required and the degree of
bleaching necessary to attain the desired shade. Generally, the
weight ratio of tint formulation:developer formulation is in the
range 5:1 to 1:5, such as 1:1, 1:2 and 1:3 depending on strength of
developer composition and tint composition.
[0144] A tint compositions of Table 8 and the developer
compositions of Table 9 ware mixed in a 1:1 weight ratio to form an
hair colorant composition of the invention. The hair colorant
composition is introduced into the container of a squeeze foamer
such as that shown in FIG. 1. The device is squeezed and the hair
colorant composition is dispensed as foam of acceptable
quality.
[0145] The dimensions and values disclosed herein are not to be
