## Title
Cosmetic compositions comprising at least one silicone copolymer and at least one additional silicone, and uses thereof

## Abstract

Cosmetic compositions comprising, in a cosmetically acceptable medium, at least one silicone copolymer with a dynamic viscosity ranging from 1×106 to 100×106 cP and at least one additional silicone. This combination can give cosmetic properties, such as at least one of smoothness, lightness, and softness, without the phenomenon of regressing keratin fibers. These compositions can be used for washing and/or conditioning a keratin material, such as the hair or the skin.

## Background
The present invention relates to novel cosmetic compositions comprising, in a cosmetically acceptable medium, at least one silicone copolymer defined below, with a dynamic viscosity ranging from 1×106 to 100×106 cP and at least one additional silicone.
It is well known that hair that has been sensitized (i.e. damaged and/or embrittled) to varying degrees under the action of atmospheric agents or mechanical or chemical treatments, such as dyes, bleaches and/or permanent-waving, can be often difficult to disentangle and to style, and may lack softness.
It has already been recommended to use conditioners, in particular cationic polymers or silicones, in compositions for washing or caring for keratin materials such as the hair, in order to facilitate the disentangling of the hair and to give it softness and suppleness. However, the cosmetic advantages mentioned above can be accompanied, on dried hair, by certain cosmetic effects considered undesirable, i.e., lankness of the hairstyle (lack of lightness of the hair) and lack of smoothness (hair not uniform from the root to the tip).
In addition, the use of cationic polymers for this purpose may have various drawbacks. On account of their high affinity for the hair, some of these polymers can become deposited thereon to a large extent during repeated use, and may lead to adverse effects such as an unpleasant, laden feel, stiffening of the hair and interfiber adhesion which may affect styling. These drawbacks may be more accentuated in the case of fine hair, which lacks liveliness and body.
In summary, it is found that the current cosmetic compositions comprising cationic silicones and/or cationic surfactants are not always entirely satisfactory.
The inventors have now discovered that the combination of at least one silicone copolymer defined below, with a dynamic viscosity ranging from 1×106 to 100×106 cP, with at least one additional silicone makes it possible to overcome at least one of these drawbacks.
Thus, after considerable research conducted in this matter, the inventors have found that by introducing at least one silicone copolymer with a dynamic viscosity ranging from 1×106 to 100×106 cP, into compositions, such as hair compositions containing at least one additional silicone, it is possible to limit, or even eliminate, the problems generally associated with the use of such compositions, i.e., for example, the lankness (charged feel following repeated applications) and the lack of smoothness and softness of the hair, while at the same time retaining at least one of the other advantageous cosmetic properties which are associated with conditioner-based compositions.
Moreover, when applied to the skin, for example in the form of a bubble bath or shower gel, the compositions of the invention can provide an improvement in the softness of the skin.
Thus, according to the present invention, cosmetic compositions are now proposed comprising, in a cosmetically acceptable medium, at least one silicone copolymer defined below, wherein said copolymer has a dynamic viscosity ranging from 1×106 to 100×106 cP, and at least one additional silicone.
Another subject of the invention relates to the use of at least one silicone copolymer defined below, with a dynamic viscosity ranging from 1×106 to 100×106 cP, in, or for the manufacture of, a cosmetic composition comprising at least one additional silicone.
The various subjects of the invention will now be described in detail. All the meanings and definitions of the compounds used in the present invention given below are valid for all the subjects of the invention.
The at least one silicone copolymer results from the addition reaction, in the presence of a catalyst, of at least:
(a) one polysiloxane of formula (I):




in which:

    
    
        R1, which may be identical or different, are independently chosen from groups that can react by chain addition reaction such as, for example, a hydrogen atom or aliphatic groups comprising an ethylenic unsaturation, such as vinyl, allyl and hexenyl groups;
        R2 in formula (I), which may be identical or different, are independently chosen from alkyl, alkenyl, cycloalkyl, aryl, hydroxyl, and alkylaryl groups, and can optionally further comprise functional groups chosen from ethers, amines, carboxyls, hydroxyls, thiols, esters, sulfonates and sulfates; wherein:
        
            the alkyl groups comprise, for example, 1 to 20 carbon atoms; the alkenyl groups comprise, for example, from 2 to 10 carbon atoms; the cycloalkyl groups comprise, for example, 5 or 6 carbon atoms; the aryl groups comprise, for example, phenyl groups; and the alkylaryl groups comprise, for example, from 7 to 20 carbon atoms;
            In one embodiment, R2 is chosen from methyl.
        
        
        n is an integer wherein the polysiloxane of formula (I) has a kinematic viscosity ranging from 1 to 1×106 mm2/s, for example, n may range from 5 to 5000; and
    
    


(b) at least one silicone compound comprising at least one and not more than two groups capable of reacting with the groups R1 of the polysiloxane (a), wherein:

    
    
        at least one of the compounds of type (a) and (b) comprises an aliphatic group, such as a C2-C6 aliphatic group, comprising an ethylenic unsaturation.
    
    


The compounds of type (b) can be another polysiloxane of type (a) in which at least one and not more than two groups R1 of the polysiloxane (b) can react with the groups R1 of the polysiloxane (a).
In one embodiment, the at least one silicone copolymer is obtained by addition reaction, in the presence of a hydrosilylation catalyst (for example a platinum catalyst), of at least:
(a) one α,ω-divinylpolydimethylsiloxane, and
(b) one α,ω-dihydrogenopolydimethylsiloxane.
The silicone copolymer generally has a dynamic viscosity, measured at a temperature of about 25° C. and at a shear rate of 0.01 Hz for a stress of 1500 Pa, ranging from 1×106 to 100×106 cP, such as ranging from 5×106 cP to 30×106 cP.
All the dynamic viscosity measurements given in the present patent application were taken at a temperature of about 25° C., on a Carri-Medium CSL2-500 machine.
The kinematic viscosity is measured, for example, at 25° C. according to ASTM standard 445 Appendix C.
The at least one silicone copolymer according to the invention is essentially non-crosslinked, i.e., not crosslinked to an extent sufficient to be referred to as a crosslinked copolymer.
Another subject of the invention relates to compositions wherein the at least one silicone copolymer present in the composition is in the form of an aqueous emulsion.
The expression “aqueous emulsion” means an emulsion of oil-in-water type in which the at least one silicone copolymer is dispersed, such as in the form of particles or droplets, in the aqueous phase forming the continuous phase of the emulsion. This emulsion can be stabilized with a common emulsifying system.
This silicone emulsion can have a silicone droplet or particle size ranging from 10 nm to 50 μm, such as from 0.3 μm to 20 μm. The particle size is measured by laser granulometry.
The emulsifying system comprises at least one surfactant commonly used in silicone emulsions. These surfactants may be nonionic, cationic, anionic or amphoteric, or mixtures thereof, such as those described below.
The emulsifying system represents, for example, from 0.5% to 10% by weight relative to the total weight of the emulsion.
The synthesis of these silicone emulsions is described for example in patent application EP-A-874 017, the disclosure of which is incorporated by reference herein.
Such emulsions are sold for example under the name DC2-1997 Cationic Emulsion by the company Dow Corning. This emulsion comprises an α,ω-divinyl-dimethicone/α,ω-dihydrogenodimethicone copolymer with a dynamic viscosity of about 15×106 cP, an emulsifier of cationic type such as cetyltrimethylammonium chloride, a stabilizer such as hydroxyethylcellulose, and water.
The at least one silicone copolymer can be present in a representative amount ranging from 0.05% to 10% by weight relative to the total weight of the composition, such as from 0.1% to 5% by weight relative to the total weight of the composition.
The aqueous emulsion of the at least one silicone copolymer can be present in a representative amount ranging from 0.5% to 15% by weight relative to the total weight of the composition.
The silicones, other than the silicone copolymer of the invention defined above that can be used in accordance with the invention can, for example, be chosen from polyorganosiloxanes that are insoluble in the composition and that can be chosen from oils, waxes, resins and gums.
Such polyorganosiloxanes, which can be volatile or non-volatile, are defined in greater detail in the book by Walter Noll “Chemistry and Technology of Silicones” (1968) Academic Press.
Volatile polyorganosiloxanes can be chosen from those having a boiling point ranging from 60° C. to 260° C., and, for example, chosen from:
(i) cyclic polyorganosiloxanes comprising from 3 to 7 and preferably from 4 to 5 silicon atoms. Such polyorganosiloxanes, for example, can be chosen from at least one octamethylcyclotetrasiloxane, sold for example under the name “Volatile Silicone 7207” by Union Carbide, and “Silbione 70045 V 2” by Rhone-Poulenc; and decamethylcyclopentasiloxane, sold under the name “Volatile Silicone 7158” by Union Carbide, and “Silbione 70045 V 5” by Rhone-Poulenc.

This is, for example, decamethyltetrasiloxane, sold for example under the name “SH 200” by the company Toray Silicone. Silicones forming part of this category are also described in the article published in Cosmetics and Toiletries, Vol. 91, Jan. 76, pp. 27-32, Todd & Byers “Volatile Silicone Fluids for Cosmetics”.

In the context of the present invention, their nature is not of critical importance.
Representative anionic surfactants include salts (for example alkaline salts, such as sodium salts, ammonium salts, amine salts, amino alcohol salts and magnesium salts) of the following compounds: alkyl sulfates, alkyl ether sulfates, alkylamidoether sulfates, alkylarylpolyether sulfates, monoglyceride sulfates; alkyl sulfonates, alkyl phosphates, alkylamide sulfonates, alkylaryl sulfonates, α-olefin sulfonates, paraffin sulfonates; alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates; alkyl sulfosuccinamates; alkyl sulfoacetates; alkyl ether phosphates; acyl sarcosinates; acyl isethionates and N-acyltaurates. The alkyl and acyl radicals of all of these various compounds can for example comprise from 8 to 24 carbon atoms, and the aryl radicals can for example be chosen from phenyl and benzyl groups.
For example, anionic surfactants can be chosen from fatty acid salts such as the salts of oleic, ricinoleic, palmitic and stearic acids, coconut oil acid and hydrogenated coconut oil acid and acyl lactylates in which the acyl radical comprises from 8 to 20 carbon atoms. At least one weakly anionic surfactant can also be used, such as alkyl-D-galactosiduronic acids and their salts, as well as polyoxyalkylenated (C6-C24) alkyl ether carboxylic acids, polyoxyalkylenated (C6-C24) alkylaryl ether carboxylic acids, polyoxyalkylenated (C6-C24) alkylamido ether carboxylic acids and their salts, for example, those comprising from 2 to 50 ethylene oxide groups.
As a further example, the anionic surfactant can be at least one salt chosen from alkyl sulfate salts and alkyl ether sulfate salts.
(ii) Nonionic Surfactant(s):
Useful nonionic surfactants include compounds that are well known per se (see for example in this respect “Handbook of Surfactants” by M. R. Porter, published by Blackie & Son (Glasgow and London), 1991, pp. 116-178), the disclosure of which is incorporated by reference herein, and, in the context of the present invention, their nature is not a critical feature. Thus, nonionic surfactants can include polyethoxylated, polypropoxylated and polyglycerolated fatty acids, alkylphenols, α-diols and alcohols having a fatty aliphatic chain comprising, for example, 8 to 18 carbon atoms, it being possible for the number of ethylene oxide and propylene oxide groups to range for example from 2 to 50 and for the number of glycerol groups to range for example 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 for example comprising from 2 to 30 mol of ethylene oxide, polyglycerolated fatty amides comprising on average 1 to 5, such as from 1.5 to 4, glycerol groups; polyethoxylated fatty amines for example comprising from 2 to 30 mol of ethylene oxide; oxyethylenated fatty acid esters of sorbitan comprising 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 (C10-C14)alkylamine oxides and N-acylaminopropylmorpholine oxides. It will be noted that the alkylpolyglycosides are nonionic surfactants that can be suitable in the context of the present invention.
(iii) Amphoteric Surfactant(s):
Representative amphoteric surfactants, whose nature is not a critical feature in the context of the present invention, can be chosen from aliphatic secondary and tertiary amine derivatives in which the aliphatic radical is chosen from linear and branched chain radicals comprising 8 to 22 carbon atoms and comprising at least one water-soluble anionic group (chosen for example from carboxylate, sulfonate, sulfate, phosphate and phosphonate); mention may also be made of (C8-C20)alkylbetaines, sulfobetaines, (C8-C20)alkylamido(C1-C6)alkylbetaines and (C8-C20)alkylamido(C1-C6)alkylsulfobetaines.
