Description
[0001] The present invention relates to a cosmetic or
dermatological composition for treating keratin substances, in
particular the hair, comprising at least one grafted silicone
polymer with a polysiloxane skeleton grafted with non-silicone
organic monomers, and at least one aqueous dispersion of insoluble
particles of nonionic or cationic polymer.
[0002] It has been proposed to use aqueous dispersions of insoluble
polymer particles in compositions for maintaining the hairstyle.
However, the results obtained hitherto are still not satisfactory.
The reason for this is that the fixing power is still not
sufficient, the drying time is long and the cosmetic properties are
still not satisfactory. Furthermore, the polymer is difficult to
remove from the hair during washing with a shampoo.
[0003] Polymers with a polysiloxane skeleton grafted with
non-silicone organic monomers are also known in the prior art. They
are preferably chosen from those described in patent applications
EP-A-0,582,152 and WO 93/23009. They are used in particular in hair
compositions for their styling properties.
[0004] Compositions for washing and/or caring for and/or treating
the hair containing styling polymers of this type in their
formulation generally have the drawback of having a fixing power
which is still insufficient.
[0005] The expression fixing power of the composition will be
understood to denote the ability of this composition to give the
hair cohesion such that the initial shape of the hairstyle is
retained.
[0006] Compositions are thus still sought which do not have the
drawbacks described above.
[0007] The Applicant has discovered, surprisingly, that by
combining at least one silicone polymer having a polysiloxane
skeleton grafted with non-silicone organic monomers with at least
one dispersion of insoluble particles of nonionic or cationic
polymer, the abovementioned drawbacks are overcome.
[0008] These compositions have good fixing power and good cosmetic
properties such as disentangling and styling or brushing of the
hair after application, the softness, the feel and the smoothness
of the hair.
[0009] The composition according to the invention is thus
essentially characterized in that it comprises, in a cosmetically
or dermatologically acceptable medium, at least one grafted
silicone polymer with a polysiloxane skeleton grafted with
non-silicone organic monomers and at least one dispersion of
insoluble particles of nonionic or cationic polymer.
[0010] In the following text, in accordance with what is generally
accepted, the term silicone polymer is understood to denote any
organosilicon polymer or oligomer having a linear or cyclic,
branched or crosslinked structure of variable molecular weight,
obtained by polymerization and/or polycondensation of suitably
functionalized silanes, and consisting essentially of a repetition
of main units in which the silicon atoms are linked together by
oxygen atoms (siloxane bonding .ident.Si--O--Si.ident.), optionally
substituted hydrocarbon radicals being linked directly via a carbon
atom to the said silicon atoms. The most common hydrocarbon
radicals are alkyl radicals, especially C.sub.1-C.sub.10 alkyl
radicals, and in particular methyl, fluoroalkyl radicals, aryl
radicals and in particular phenyl, and alkenyl radicals and in
particular vinyl; other types of radicals which can be linked,
either directly or via a hydrocarbon radical, to the siloxane chain
are, especially, hydrogen, halogens and in particular chlorine,
bromine or fluorine, thiols, alkoxy radicals, polyoxyalkylene (or
polyether) radicals and in particular polyoxyethylene and/or
polyoxypropylene, hydroxyl or hydroxyalkyl radicals, substituted or
unsubstituted amine groups, amide groups, acyloxy radicals or
acyloxyalkyl radicals, hydroxyalkylamino or aminoalkyl radicals,
quaternary ammonium groups, amphoteric or betaine groups, anionic
groups such as carboxylates, thioglycolates, sulphosuccinates,
thiosulphates, phosphates and sulphates, needless to say this list
not being limiting in any way (so-called "organomodified"
silicones).
[0011] According to the present invention, the grafted silicone
polymer(s) which is (are) to be used is (are) that (those) which
comprise(s) a main silicone (or polysiloxane
(.ident.Si--O--).sub.n) chain on which is grafted, inside the said
chain as well as, optionally, on at least one of its ends, at least
one organic group containing no silicone.
[0012] These silicone polymers can be existing commercial products
or alternatively can be obtained according to any means known to
those skilled in the art, in particular by reaction between (i) a
starting silicone which is correctly functionalized on one or more
of these silicon atoms, and (ii) a non-silicone organic compound
which is itself correctly functionalized with a function which is
capable of reacting with the functional group(s) borne by the said
silicone, forming a covalent bond; a classic example of such a
reaction is the hydrosilylation reaction between .ident.Si--H
groups and vinyl groups CH.sub.2.dbd.CH--, or alternatively the
reaction between thio functional groups --SH with these same vinyl
groups.
[0013] Examples of silicone polymers which are suitable for
carrying out the present invention, as well as their specific mode
of preparation, are described in particular in patent applications
EP-A-0,582,152, WO 93/23009 and WO 95/03776, the teachings of which
are included in their entirety in the present description by way of
non-limiting references.
[0014] According to a particularly preferred embodiment of the
present invention, the silicone polymer used comprises the result
of the radical copolymerization between, on the one hand, at least
one non-silicone anionic organic monomer having ethylenic
unsaturation and/or a non-silicone hydrophobic organic monomer
having ethylenic unsaturation, and, on the other hand, a silicone
having in its chain at least one functional group capable of
reacting with the said ethylenic unsaturations of the said
non-silicone monomers, forming a covalent bond, in particular thio
functional groups.
[0015] According to the present invention, the said anionic
monomers containing ethylenic unsaturation are preferably chosen,
alone or as a mixture, from linear or branched, unsaturated
carboxylic acids, optionally partially or totally neutralized in
the form of a salt, it being possible for this (these) carboxylic
acid(s) to be, more particularly, acrylic acid, methacrylic acid,
maleic acid, maleic anhydride, itaconic acid, fumaric acid and
crotonic acid. The suitable salts are, in particular, alkali metal
salts, alkaline-earth metal salts and ammonium salts. It will
likewise be noted that, in the final grafted silicone polymer, the
organic group of anionic nature which comprises the result of the
radical (homo)polymerization of at least one anionic monomer of
unsaturated carboxylic acid type can, after reaction, be
post-neutralized with a base (sodium hydroxide, aqueous ammonia,
etc) in order to bring it into the form of a salt.
[0016] According to the present invention, the hydrophobic monomers
containing ethylenic unsaturation are preferably chosen, alone or
as a mixture, from acrylic acid esters of alkanols and/or
methacrylic acid esters of alkanols. The alkanols are preferably
C.sub.1-C.sub.18 and more particularly C.sub.1-C.sub.12. The
preferred monomers are chosen from the group consisting of isooctyl
(meth)acrylate, isononyl (meth)acrylate, 2-ethylhexyl
(meth)acrylate, lauryl (meth)acrylate, isopentyl (meth)acrylate,
n-butyl (meth)acrylate, isobutyl (meth)acrylate, methyl
(meth)acrylate, tert-butyl (meth)acrylate, tridecyl (meth)acrylate
and stearyl (meth)acrylate, or mixtures thereof.
[0017] One family of grafted silicone polymers which is
particularly suitable for carrying out the present invention
consists of silicone polymers containing in their structure the
unit of formula (I) below: 1
[0018] in which the radicals G.sub.1, which may be identical or
different, represent hydrogen or a C.sub.1-C.sub.10 alkyl radical
or alternatively a phenyl radical; the radicals G.sub.2, which may
be identical or different, represent a C.sub.1-C.sub.10 alkylene
group; G.sub.3 represents a polymer residue resulting from the
(homo)polymerization of at least one anionic monomer containing
ethylenic unsaturation; G.sub.4 represents a polymer residue
resulting from the (homo)polymerization of at least one hydrophobic
monomer containing ethylenic unsaturation; m and n are equal to 0
or 1; a is an integer ranging from 0 to 50; b is an integer which
may be between 10 and 350, c is an integer ranging from 0 to 50;
with the proviso that one of the parameters a and c is other than
0.
[0019] Preferably, the unit of formula (I) above has at least one,
and even more preferably all, of the following characteristics:
[0020] the radicals G.sub.1 denote an alkyl radical, preferably the
methyl radical;
[0021] n is non-zero and the radicals G.sub.2 represent a divalent
C.sub.1-C.sub.3 radical, preferably a propylene radical;
[0022] G.sub.3 represents a polymeric radical resulting from the
(homo)polymerization of at least one monomer of the carboxylic acid
type containing ethylenic unsaturation, preferably acrylic acid
and/or methacrylic acid;
[0023] G.sub.4 represents a polymeric radical resulting from the
(homo)polymerization of at least one monomer of the
C.sub.1-C.sub.10 alkyl (meth)acrylate type, preferably of the
isobutyl or methyl (meth)acrylate type.
[0024] Examples of silicone polymers corresponding to formula (I)
are, in particular, polydimethylsiloxanes (PDMS) on which are
grafted, via a thiopropylene-type connecting chain, mixed polymer
units of the poly(meth)acrylic acid type and of the polymethyl
(meth)acrylate type.
[0025] Other examples of silicone polymers corresponding to formula
(I) are, in particular, polydimethylsiloxanes (PDMS) on which are
grafted, via a thiopropylene-type connecting chain, polymer units
of the polyisobutyl (meth)acrylate type.
[0026] Preferably, the number-average molecular mass of the
silicone polymers of the invention, ranges approximately from
10,000 to 1,000,000 and even more preferably approximately from
10,000 to 100,000.
[0027] The grafted silicone polymers in accordance with the
invention are preferably used in an amount ranging from 0.01 to 20%
by weight relative to the total weight of the composition. More
preferably, this amount ranges from 0.1 to 15% by weight and even
more particularly from 0.5 to 10% by weight.
[0028] The aqueous dispersions of insoluble particles of nonionic
or cationic polymer which can be used according to the invention
are generally obtained by suspension or emulsion polymerization or
copolymerization of monomers according to processes that are well
known in the prior art (such dispersions are also known as
"latices"). Aqueous polymer dispersions can also be obtained by
dissolving the said polymer in a water-miscible organic solvent,
after which water is added and lastly the organic solvent is
evaporated off. This type of preparation is described, for example,
in French patent application No. 2,697,160.
[0029] The average diameter of the insoluble polymer particles is
generally less than 500 nm and preferably less than 250 nm. The
glass transition temperature is generally between -30.degree. C.
and 90.degree. C. and preferably between 10 and 35.degree. C.
[0030] The polymer of the aqueous dispersion comprises at least one
monomer chosen, for example, from styrene, butadiene, ethylene,
tetrafluoroethylene, propylene, vinyltoluene, vinyl propionate,
vinyl alcohol, acrylonitrile, chloroprene, vinyl chloride, vinyl
acetate, urethanes, isoprene, isobutene and esters or amides of
acrylic, methacrylic, maleic, crotonic or itaconic acid, vinyl
ethers, vinylpyrrolidone, vinylimidazole, trimethylammonioethyl
(meth)acrylate and mixtures thereof.
[0031] The aqueous dispersions which can be used according to the
invention can come from the condensation of ionic or nonionic
monomers giving nonionic or cationic polymers, such as, for
example, polyesters, polyamides, polyurethanes or polyethers.
[0032] The nonionic polymers in the aqueous dispersions which can
be used according to the present invention are chosen, for example,

the name Appretan EM by the company Hoechst or the product sold

are particularly preferred in the context of the invention are
aqueous dispersions of insoluble particles of nonionic polymer.
[0057] The weight concentration of the insoluble polymer particles
in the compositions according to the invention is preferably
between 0.1 and 50% by weight relative to the total weight of the
composition, and preferably between 1 and 30%.
[0058] The cosmetically or dermatologically acceptable medium
preferably consists of water or a mixture of water and cosmetically
acceptable solvents such as monoalcohols, polyalcohols, glycol
ethers or fatty acid esters, which can be used alone or as a
mixture.
[0059] Mention may be made more particularly of lower alcohols such
as ethanol and isopropanol, polyalcohols such as diethylene glycol,
glycol ethers, glycol alkyl ethers or diethylene glycol alkyl
ethers.
[0060] The grafted silicone polymers according to the invention can
be dissolved in the said cosmetically acceptable medium or used in
the form of an aqueous dispersion of insoluble particles.
[0061] The composition of the invention can also contain at least
one additive chosen from thickeners, fatty acid esters, fatty acid
esters of glycerol, volatile silicones, surfactants, fragrances,
preserving agents, sunscreens, proteins, vitamins, polymers, plant,
animal, mineral or synthetic oils or any other additive
conventionally used in the cosmetics field.
[0062] These additives are present in the composition according to
the invention in proportions which can range from 0 to 20% by
weight relative to the total weight of the composition. The precise
amount of each additive depends on its nature and is determined
easily by those skilled in the art.
[0063] Needless to say, a person skilled in the art will take care
to select the optional compound(s) to be added to the composition
according to the invention such that the advantageous properties
intrinsically associated with the composition in accordance with
the invention are not, or are not substantially, adversely affected
by the addition envisaged.
[0064] The compositions according to the invention can be in the
form of a gel, a milk, a cream, a relatively thickened lotion or a
mousse.
[0065] The compositions of the invention are used as rinse-out
products or as leave-in products in particular to wash, care for,
condition, maintain the style of or shape keratin substances such
as the hair.
[0066] These compositions are more particularly styling products
such as hairsetting lotions, blow-drying lotions, fixing
compositions (lacquers) and styling compositions. The lotions can
be packaged in various forms, in particular in vaporizers,
pump-dispenser bottles or in aerosol containers in order to ensure
application of the composition in vaporized form or in the form of
a mousse. Such packaging forms are indicated, for example, when it
is desired to obtain a spray, a lacquer or a mousse for fixing or
treating the hair.
[0067] The compositions can also be shampoos, rinse-out or leave-in
compositions, to be applied before or after shampooing, dyeing,
bleaching, permanent-waving or straightening the hair.
[0068] When the composition according to the invention is packaged
in aerosol form in order to obtain a lacquer or an aerosol mousse,
it comprises at least one propellant which can be chosen from
volatile hydrocarbons such as n-butane, propane, isobutane,
pentane, a chloro and/or fluoro hydrocarbon, and mixtures thereof.
Carbon dioxide, nitrous oxide, dimethyl ether, nitrogen or air,
which is compressed, and mixtures thereof, can also be used as
propellant.
[0069] Another subject of the invention is a process for treating
keratin substances such as the hair, which consists in applying a
composition as defined above to the hair and then optionally in
rinsing with water.
[0070] The invention will now be illustrated more fully with the
aid of the examples which follow, which should not be considered as
limiting it to the embodiments described. In the text which
follows, AM means active material.
