Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims priority under 37 U.S.C. .sctn. 119
(e) to U.S. Provisional Application Ser. No. 60/483,350, filed Jun.
27, 2003.
FIELD OF THE INVENTION
[0002] The present invention relates to compositions containing an
antimicrobial agent for treating fabric articles, especially
articles of clothing, linens and drapery, wherein the compositions
provide improved cleaning of soils from and/or care of and/or
treatment of fabric articles, especially while providing superior
garment care for articles sensitive to water as compared to
conventional fabric article treating compositions.
BACKGROUND OF THE INVENTION
[0003] For the cleaning of fabric articles consumers currently have
the choice of conventional laundry cleaning or dry cleaning.
[0004] Conventional laundry cleaning is carried out with relatively
large amounts of water, typically in a washing machine at the
consumer's home, or in a dedicated place such as a coin laundry.
Although washing machines and laundry detergents have become quite
sophisticated, the conventional laundry process still exposes the
fabric articles to a risk of dye transfer and shrinkage.
Significant portions of fabric articles used by consumers are not
suitable for cleaning in a conventional laundry process. Even
fabric articles that are considered "washing machine safe"
frequently come out of the laundry process badly wrinkled and
require ironing.
[0005] Dry cleaning processes rely on non-aqueous solvents for
cleaning. By avoiding water these processes minimize the risk of
shrinkage and wrinkling; however, cleaning of soils, particularly
water-based and alcohol-based soils, is very limited with these
processes. Typically, the dry-cleaner removes such soils by hand
prior to the dry-cleaning process. These methods are complex,
requiring a wide range of compositions to address the variety of
stains encountered, very labor intensive and often result in some
localized damage to the treated article.
[0006] Accordingly there is an unmet need, in commercial laundry,
in dry-cleaning and in the home, for fabric article treating
compositions, which simultaneously provide acceptable cleaning of
across a variety of soils while remaining safe for a wide range of
fabric articles.
SUMMARY OF THE INVENTION
[0007] The present invention provides compositions which exhibit
improved cleaning of soils from and/or care of and/or treatment of
fabric articles. These benefits may be delivered to the fabric
article treated by the compositions of the present invention while
maintaining excellent fabric care properties.
[0008] In one aspect of the present invention, a fabric article
treating composition comprises:
[0009] a) a lipophilic fluid; and
[0010] b) an antimicrobial agent; and
[0011] c) optionally, a surfactant component capable of enhancing
soil removal benefits of a lipophilic fluid and/or capable of
suspending water in a lipophilic fluid; and
[0012] d) optionally, a non-silicone additive capable of further
enhancing soil removal by the composition; and
[0013] e) optionally, water; and
[0014] f) optionally, other cleaning adjuncts; and
[0015] g) optionally, processing aids;
[0016] wherein the composition is capable of suspending water in a
lipophilic fluid, is provided.
[0017] In another aspect of the present invention, a consumable
detergent composition comprises:
[0018] a) a surfactant component capable of enhancing soil removal
benefits of a lipophilic fluid and/or capable of suspending water
in a lipophilic fluid; and
[0019] b) an antimicrobial agent; and
[0020] c) optionally, a non-silicone additive capable of further
enhancing soil removal by the composition; and
[0021] d) optionally, a polar solvent; and
[0022] e) optionally, other cleaning adjuncts; and
[0023] f) optionally, lipophilic fluid; and
[0024] g) optionally, processing aids;
[0025] wherein the composition is capable of suspending water in a
lipophilic fluid, is provided.
[0026] These and other aspects, features and advantages will become
apparent to those of ordinary skill in the art from reading the
following detailed description and the appended claims. All
percentages, ratios and proportions herein are by weight, unless
otherwise specified. All temperatures are in degrees Celsius
(.degree. C.) unless otherwise specified. All measurements are in
SI units unless otherwise specified. All documents cited are, in
relevant part, incorporated herein by reference.
DETAILED DESCRIPTION OF THE INVENTION
DEFINITIONS
[0027] The term "fabric article" used herein is intended to mean
any article that is customarily cleaned in a conventional laundry
process or in a dry cleaning process. As such, the term encompasses
articles of clothing, linens, drapery, and clothing accessories.
The term also encompasses other items made in whole or in part of
fabric, such as tote bags, furniture covers, tarpaulins and the
like.
[0028] The term "fabric article treating composition" used herein
is intended to mean any lipophilic fluid-containing composition
containing cleaning and/or care additives that comes into direct
contact with fabric articles to be cleaned. It should be understood
that the term "fabric article treating composition" encompasses
uses other than cleaning, such as conditioning and sizing.
Furthermore, optional cleaning adjuncts such as additional
surfactants other than those surfactants described above, bleaches,
and the like may be added to the "fabric article treating
composition". That is, cleaning adjuncts may be optionally combined
with the lipophilic fluid. These optional cleaning adjuncts are
described in more detail hereinbelow. Such cleaning adjuncts may be
present in the fabric article treating compositions of the present
invention at a level of from about 0.01% to about 10% by weight of
the fabric article treating composition.
[0029] The term "soil" means any undesirable substance on a fabric
article that is desired to be removed. By the terms "water-based"
or "hydrophilic" soils, it is meant that the soil comprised water
at the time it first came in contact with the fabric article, or
the soil retains a significant portion of water on the fabric
article. Examples of water-based soils include, but are not limited
to, beverages, many food soils, water soluble dyes, bodily fluids
such as sweat, urine or blood, and outdoor soils such as grass
stains and mud.
[0030] The term "capable of suspending water in a lipophilic fluid"
means that a material is able to suspend, solvate and/or emulsify
water, in a way that the water remains visibly suspended, solvated
or emulsified when left undisturbed for a period of at least five
minutes after initial mixing of the components. In some examples of
compositions in accordance with the present invention, the
compositions may be colloidal in nature and/or appear milky. In
other examples of compositions in accordance with the present
invention, the compositions may be transparent.
[0031] The term "insoluble in a lipophilic fluid" means that when
added to a lipophilic fluid, a material physically separates from
the lipophilic fluid (i.e. settle-out, flocculate, float) within 5
minutes after addition, whereas a material that is "soluble in a
lipophilic fluid" does not physically separate from the lipophilic
fluid within 5 minutes after addition.
[0032] The term "consumable detergent composition" means any
detersive composition, that when combined with a discrete
lipophilic fluid, results in a fabric article treating composition
according to the present invention.
[0033] The term "processing aid" refers to any material that
renders the consumable detergent composition more suitable for
formulation, stability, and/or dilution with a lipophilic fluid to
form a fabric article treating composition in accordance with the
present invention.
[0034] The term "mixing" as used herein means combining two or more
materials (i.e., more specifically a discrete lipophilic fluid and
a detergent composition in accordance with the present invention)
in such a way that a homogeneous mixture or stable dispersion or
suspension is formed. Suitable mixing processes are known in the
art. Nonlimiting examples of suitable mixing processes include
vortex mixing processes and static mixing processes.
[0035] "Solvent compatibility group", as used herein, means any
hydrocarbon, silicone, polyalkylene oxide (ethoxy, propoxy, butoxy,
etc. and mixtures) or flurorinated groups. Hydrocarbon groups may
be linear, cyclic, branched, saturated or unsaturated straight and
branched chain linear aliphatic; saturated and unsaturated cyclic
aliphatic, including heterocyclic aliphatic; or mononuclear or
polynuclear aromatics, including heterocyclic aromatics.
Polyoxyalkylene groups may comprise of one or more or a mixture of
alkoxy repeat units. Silicone and fluorinated groups may consist of
one or more or a mixture of repeat units.
[0036] "Functionalized", as used herein, means the indicated
solvent compatibility groups are chemically bonded to the
polyol.
[0037] A "functional unit", as used herein, means one solvent
compatibility group used to functionalize the polyol.
COMPOSITIONS OF THE PRESENT INVENTION
[0038] The present invention provides compositions which exhibit
improved cleaning of soils (i.e., removal and/or reduction of
soils) from and/or care of and/or treatment of fabric articles.
These benefits may be delivered to the fabric article treated by
the compositions of the present invention while maintaining
excellent fabric care properties.
[0039] Lipophilic Fluid
[0040] "Lipophilic fluid" as used herein means any liquid or
mixture of liquid that is immiscible with water at up to 20% by
weight of water. In general, a suitable lipophilic fluid can be
fully liquid at ambient temperature and pressure, can be an easily
melted solid, e.g., one that becomes liquid at temperatures in the
range from about 0.degree. C. to about 60.degree. C., or can
comprise a mixture of liquid and vapor phases at ambient
temperatures and pressures, e.g., at 25.degree. C. and 1 atm.
pressure.
[0041] It is preferred that the lipophilic fluid herein be
non-flammable or, have relatively high flash points and/or low VOC
characteristics, these terms having conventional meanings as used
in the dry cleaning industry, to equal or, preferably, exceed the
characteristics of known conventional dry cleaning fluids.
[0042] Non-limiting examples of suitable lipophilic fluid materials
include siloxanes, other silicones, hydrocarbons, glycol ethers,
glycerine derivatives such as glycerine ethers, perfluorinated
amines, perfluorinated and hydrofluoroether solvents,
low-volatility nonfluorinated organic solvents, diol solvents,
other environmentally-friendly solvents and mixtures thereof.
[0043] "Siloxane" as used herein means silicone fluids that are
non-polar and insoluble in water or lower alcohols. Linear
siloxanes (see for example U.S. Pat. Nos. 5,443,747, and 5,977,040)
and cyclic siloxanes are useful herein, including the cyclic
siloxanes chosen from octamethyl-cyclotetrasiloxane (tetramer),
dodecamethyl-cyclohexasiloxane (hexamer), and preferably
decamethyl-cyclopentasiloxane (pentamer, commonly referred to as
"D5"). A preferred siloxane comprises more than about 50% cyclic
siloxane pentamer, more preferably more than about 75% cyclic
siloxane pentamer, most preferably at least about 90% of the cyclic
siloxane pentamer. Also preferred for use herein are siloxanes that
are a mixture of cyclic siloxanes having at least about 90%
(preferably at least about 95%) pentamer and less than about 10%
(preferably less than about 5%) tetramer and/or hexamer.
[0044] The lipophilic fluid can include any fraction of
dry-cleaning solvents, especially newer types including fluorinated
solvents, or perfluorinated amines. Some perfluorinated amines such
as perfluorotributylamines, while unsuitable for use as lipophilic
fluid, may be present as one of many possible adjuncts present in
the lipophilic fluid-containing composition.
[0045] Other suitable lipophilic fluids include, but are not
limited to, diol solvent systems e.g., higher diols such as C.sub.6
or C.sub.8 or higher diols, organosilicone solvents including both
cyclic and acyclic types, and the like, and mixtures thereof.
[0046] Non-limiting examples of low volatility non-fluorinated
organic solvents include for example OLEAN.RTM. and other polyol
esters, or certain relatively nonvolatile biodegradable mid-chain
branched petroleum fractions.

glycol methyl ether, dipropylene glycol n-propyl ether, dipropylene
glycol t-butyl ether, dipropylene glycol n-butyl ether,
tripropylene glycol methyl ether, tripropylene glycol n-propyl
ether, tripropylene glycol t-butyl ether, tripropylene glycol
n-butyl ether.
[0048] Non-limiting examples of other silicone solvents, in
addition to the siloxanes, are well known in the literature, see,
for example, Kirk Othmer's Encyclopedia of Chemical Technology, and
are available from a number of commercial sources, including GE
Silicones, Toshiba Silicone, Bayer, and Dow Corning. For example,
one suitable silicone solvent is SF-1528 available from GE
Silicones.
[0049] Non-limiting examples of suitable glycerine derivative
solvents for use in the methods and/or apparatuses of the present
invention include glycerine derivatives having the following

[0052] Non-limiting examples of other environmentally-friendly
solvents include lipophilic fluids that have an ozone reactivity of
from about 0 to about 0.31, lipophilic fluids that have a vapor
pressure of from about 0 to about 0.1 mm Hg, and/or lipophilic
fluids that have a vapor pressure of greater than 0.1 mm Hg, but
have an ozone reactivity of from about 0 to about 0.31.
Non-limiting examples of such lipophilic fluids that have not
previously been described above include carbonate solvents (i.e.,
methyl carbonates, ethyl carbonates, ethylene carbonates, propylene
carbonates, glycerine carbonates) and/or succinate solvents (i.e.,
dimethyl succinates).
[0053] "Ozone Reactivity" as used herein is a measure of a VOC's
ability to form ozone in the atmosphere. It is measured as grams of
ozone formed per gram of volatile organics. A methodology to
determine ozone reactivity is discussed further in W. P. L. Carter,
"Development of Ozone Reactivity Scales of Volatile Organic
Compounds", Journal of the Air & Waste Management Association,
Vol. 44, Page 881-899, 1994. "Vapor Pressure" as used can be
measured by techniques defined in Method 310 of the California Air
Resources Board.
[0054] Preferably, the lipophilic fluid comprises more than 50% by
weight of the lipophilic fluid of cyclopentasiloxanes, ("D5")
and/or linear analogs having approximately similar volatility, and
optionally complemented by other silicone solvents.
