Description

This application is a PCT/FR98/02688, filed Dec. 10, 1998.

The present invention relates to novel compositions for treating keratin substances, in particular the hair, containing a combination of a zwitterionic polymer and a non-amino, non-volatile, water-insoluble silicone, and to their uses and processes.

Hair conditioners which provide additional cosmetic effects after application and rinsing, such as softness, flexibility, good disentangling, a sheen effect and/or a styling effect, have been sought in recent years in the field of shampoos and conditioners.

It is known in the prior art that silicones are cosmetic products which are particularly desired in hair formulations for their hair-conditioning properties, their softening and disentangling properties and for the sheen effect they provide. When they are used in rinse-out hair compositions, these ingredients have the drawback of being difficult to deposit on the hair and to do so in a non-uniform manner when applied and after rinsing, and of not being able to give the hair the desired effects intrinsic to silicones.

Shampoo compositions based on zwitterionic polymers comprising a monomer of quaternary ammonium type and a monomer of carboxylic acid type are envisaged in patent application WO 91/03229. These polymers, used alone, do not make it possible to obtain satisfactory cosmetic properties either.

Combining silicones with an amphoteric polymer of the acrylic acid/diallyldimethylammoniun chloride type has also been envisaged in patent U.S. Pat. No. 5,650,383. These combinations are still not entirely satisfactory.

The Applicant has now discovered that by combining specific zwitterionic polymers with non-amino, non-volatile, water-insoluble silicones of viscosity which will be defined later, it is possible to obtain, surprisingly, cosmetic compositions based on non-amino silicones which do not have the drawbacks mentioned above, and which give enhanced cosmetic performance, in particular as regards the feel and the disentangling, as well as good styling properties.

In particular, this combination promotes the deposition of silicone onto keratin substances.

Moreover, the Applicant has discovered, unexpectedly, that by combining the silicones of the invention with the zwitterionic polymers defined below, the cosmetic performance of the zwitterionic polymer is markedly enhanced.

A subject of the invention is thus cosmetic or dermatological compositions, characterized in that they comprise, in a cosmetically and/or dermatologically acceptable aqueous medium, at least:

a) one zwitterionic polymer resulting from the copolymerization of at least one monomer of formula (I):

 in which R 1 and R 2 , which may be identical or different, represent a hydrogen atom or a methyl radical, and R 3 , R 4 and R 5 , which may be identical or different, represent a linear or branched alkyl radical containing from 1 to 4 carbon atoms,

Z represents an NH group or an oxygen atom,

n is an integer from 2 to 5,

A − is an anion derived from an organic or inorganic acid,

 and at least one monomer of formula (II):

R 6 —CH═CR 7 —COOH  (II)

 in which R 6 and R 7 , which may be identical or different, represent a hydrogen atom or a methyl radical;

the said polymer being soluble in water to a concentration of 1% by weight at a pH below 6 and at 20° C.;

b) one non-amino, non-volatile, water-insoluble silicone with a viscosity of greater than 3×10 −5 m 2 /s (300 centistokes).

A subject of the invention is also the use of a zwitterionic polymer defined above in a composition comprising a non-amino, non-volatile, water-insoluble silicone to enhance the conditioning effect of the silicone.

According to the present invention, the expression “keratin substances” means the hair, the eyelashes, the eyebrows, the skin, the nails, mucous membranes or the scalp, and more particularly the hair.

The monomers of formula (I) of the present invention are preferably chosen from the group consisting of:

dimethylaminoethyl methacrylate, dimethylaminoethyl acrylate,

diethylaminoethyl methacrylate, diethylaminoethyl acrylate,

dimethylaminopropyl methacrylate, dimethylaminopropyl acrylate,

dimethylaminopropylmethacrylamide, dimethylaminopropylacrylamide, which are quaternized, for example, with a C 1 -C 4 alkyl halide or a C 1 -C 4 dialkyl sulphate.

More particularly, the monomer of formula (I) is chosen from acrylamidopropyltrimethylammonium chloride and methacrylamidopropyltrimethylammonium chloride.

The monomers of formula (II) of the present invention are preferably chosen from the group consisting of acrylic acid, methacrylic acid, crotonic acid and 2-methylcrotonic acid.

More particularly, the monomer of formula (II) is acrylic acid.

The weight-average molecular weights of the zwitterionic polymers can range from 500 to 50,000,000 and are preferably between 10,000 and 5,000,000.

The polymers according to the invention can also contain other monomers, such as nonionic monomers and in particular such as C 1 -C 4 alkyl acrylates or methacrylates.

The zwitterionic polymers according to the invention are described, for example, in patent application DE 3,929,973.

The zwitterionic polymers which are particularly preferred according to the invention are chosen from acrylic acid/acrylamidopropyl-trimethylammonium chloride copolymers and acrylic acid/methacrylamidopropyltrimethylammonium chloride copolymers.

The silicones of the invention preferably have a viscosity of greater than 5×10 −5 m 2 /s (500 centistokes) and more particularly greater than 10×10 −5 m 2 /s (1000 centistokes). Preferably, the silicones have a viscosity of less than 50,000,000 mm 2 /s. The viscosities are measured at 25° C.

In all the text hereinabove and hereinbelow, in accordance with that which is generally accepted, the terms “silicone” and “polysiloxane” are intended to denote any organosilicon polymer or oligomer of 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 bond ≡Si—O—Si≡), optionally substituted hydrocarbon-based radicals being linked directly via a carbon atom to the said silicon atoms.

The surfactants which are suitable for carrying out the present invention are, in particular, the following:

(i) Anionic Surfactant(s):

In the context of the present invention, their nature is not really a critical feature.

Thus, they can be chosen in particular from (non-limiting list) polyethoxylated, polypropoxylated or polyglycerolated fatty acids, alkylphenols, α-diols or alcohols having a fatty chain containing, for example, 8 to 18 carbon atoms, it being possible for the number of ethylene oxide or propylene oxide groups to range in particular from 2 to 50 and for the number of glycerol groups to range in particular from 2 to 30. Mention may also be made of copolymers of ethylene oxide and of propylene oxide, condensates of ethylene oxide and of propylene oxide with fatty alcohols; polyethoxylated fatty amides preferably having from 2 to 30 mol of ethylene oxide, polyglycerolated fatty amides containing on average 1 to 5, and in particular 1.5 to 4, glycerol groups; polyethoxylated fatty amines preferably having 2 to 30 mol of ethylene oxide; oxyethylenated fatty acid esters of sorbitan having from 2 to 30 mol of ethylene oxide; fatty acid esters of sucrose, fatty acid esters of polyethylene glycol, alkylpolyglycosides, N-alkylglucamine derivatives, amine oxides such as (C 10 -C 14 )alkylamine oxides or N-acylaminopropylmorpholine oxides.

The amphoteric or zwitterionic surfactants, whose nature is not a critical feature in the context of the present invention, can be, in particular (non-limiting list), aliphatic secondary or tertiary amine derivatives in which the aliphatic radical is a linear or branched chain containing 8 to 18 carbon atoms and containing at least one water-solubilizing anionic group (for example carboxylate, sulphonate, sulphate, phosphate or phosphonate); mention may also be made of (C 8 -C 20 )alkylbetaines, sulphobetaines, (C 8 -C 20 )alkylamido(C 1 -C 6 ) alkylbetaines or (C 8 -C 20 )alkylamido(C 1 -C 6 ) alkylsulphobetaines.

Among the amine derivatives, mention may be made of the products sold under the name Miranol, as described in U.S. Pat. Nos. 2,528,378 and 2,781,354 and classified in the CTFA dictionary, 3rd edition, 1982, under the names Amphocarboxyglycinates and Amphocarboxypropionates, with the respective structures:

R 2 —CONHCH 2 CH 2 —N(R 3 ) (R 4 ) (CH 2 COO—)  (2)

in which: R 2 denotes an alkyl radical of an acid R 2 —COOH present in hydrolysed copra oil, a heptyl, nonyl or undecyl radical, R 3 denotes a β-hydroxyethyl group and R 4 denotes a carboxymethyl group; and

By way of example, mention may be made of the cocoamphocarboxyglycinate sold under the trade name Miranol C 2 M concentrate by the company Miranol.

(iv) Cationic Surfactants:

Among the cationic surfactants, whose nature, in the context of the present invention, is not a critical feature, mention may be made in particular (non-limiting list) of: salts of optionally polyoxyalkylenated primary, secondary or tertiary fatty amines; quaternary ammonium salts such as tetraalkylammonium, alkylamidoalkyltrialkylammonium, trialkylbenzylammonium, trialkylhydroxyalkylammonium or alkylpyridinium chlorides or bromides; imidazoline derivatives; or amine oxides of cationic nature.

The cosmetically or dermatologically acceptable medium of the compositions of the invention is preferably water or an aqueous-alcoholic solution of a lower alcohol such as ethanol, isopropanol or butanol.

The composition of the invention can also contain at least one additive chosen from sequestering agents, softeners, foam modifiers, dyes, pearlescent agents, moisturizers, antidandruff agents, anti-seborrhoeic agents, suspending agents, ceramides, pseudoceramides, fatty acids containing linear or branched C 16 -C 40 chains, hydroxy acids, electrolytes, thickeners, fatty acid esters, fatty acid esters of glycerol, surfactants, fragrances, preserving agents, silicone or non-silicone sunscreens, proteins, vitamins, ionic or nonionic polymers, water-soluble silicones, plant, animal, mineral or synthetic oils and any other additive conventionally used in the cosmetics field.

These additives are present in the composition according to the invention in proportions which can range from 0 to 40% by weight relative to the total weight of the composition. The precise amount of each additive depends on its nature and is readily determined by a person skilled in the art.

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.

These compositions can be in the form of relatively thickened liquids, creams or gels and they are mainly suitable for washing, conditioning and/or styling the hair. They can also be in the form of rinse-out lotions.

Another subject of the invention consists of a cosmetic treatment process for the hair, characterized in that a composition as defined above is applied directly to the said wet substances and, after optionally leaving it thereon for a period of time, it is rinsed out with water; the said process can be repeated several times.

As mentioned above, the compositions according to the invention give the hair, after rinsing, a noteworthy conditioning effect which is manifested in particular by an ease of disentangling the hair, as well as properties of softness and smoothness of the hair, lightness and volume.

The examples which follow serve to illustrate the present invention without, however, being limiting in nature.
