Description

COSMETIC COMPOSITIONS CONTAINING A COPOLYMER VINILDIMETICONÁ / DIMETICONA AND A SILICONE AND ITS UTILIZATIONS.

Field of the Invention The present invention relates to novel cosmetic compositions comprising in a cosmetically acceptable medium at least one silicone and at least one dimethicone copolymer of ethylenic unsaturation / dimethicone.

BACKGROUND OF THE INVENTION It is well known that hair that has been sensitized (ie damaged and / or fragilized) to varying degrees under the action of atmospheric agents or under the action of mechanical or chemical treatments, such as colorations, discolorations and / or permanent, are often difficult to untangle and comb, and lack softness. Compositions for the washing or treatment of keratin materials such as hair have already been recommended in the compositions REF. : 124178 -tM ----- «- l --- mÉ * ÉlittMi-i-t t fl.? t lt. 1, -p i, - ",,. - .. *, "'" • * "« •' - • • • -. ....,... -., ._, ....- -. »-». - ^ u Of conditioning agents, particularly cationic polymers or silicones, to facilitate the disentangling of the hair and to impart softness and flexibility, however, the cosmetic advantages mentioned above are unfortunately also accompanied, in dry hair, of certain cosmetic effects judged undesirable, namely a caking of the hairstyle (lack of lightness of the hair), a lack of smoothing 10 (inhomogeneous hair from the root to the tip), In addition, the use of cationic polymers for this purpose presents several disadvantages. strong affinity for the hair, some of these polymers are importantly deposited in repeated uses, and lead to undesirable effects such as unpleasant, heavy touch, a stiffness of the hair, and an adhesion of interfibers that affects the hairstyle. disadvantages are accentuated in the case of fine hair, which lacks vividness and volume. In summary, it happens that current cosmetic compositions containing silicones do not completely satisfy. The applicant has now discovered that the association of at least one copolymer "" * - «« - -V- * i ^ -. . .. .. -4 *.. "".

Silicone with a viscosity between 10d and 100.106 cP with silicones allows to remedy these drawbacks. Thus, as a consequence of important investigations carried out on the subject, it has now been discovered by the applicant that by introducing at least one particular silicone copolymer of viscosity comprised between 106 and 100'6 cP in the particular capillary compositions of the prior art based on of silicones, it is possible to limit, even suppress, the problems generally related to the use of such compositions, namely in particular the caking (touch loaded in repeated applications), the lack of smoothing and softness of the hair, maintaining the other cosmetic properties advantageous that are inherent in the compositions based on conditioning agents. On the other hand, the compositions of the invention applied to the skin, particularly in the form of a foaming bath or shower gel, provide an improvement in the softness of the skin.

Description of the Invention Thus, according to the present invention, new cosmetic compositions are proposed, comprising, in a cosmetically acceptable medium, at least one siliconized copolymer defined below, with a viscosity comprised between 106 and 100. 106 cP and at least one silicone. Another object of the invention relates to the use of at least one silicone copolymer as defined below with a viscosity comprised between 10d and 100,106 cP in or for the manufacture of a cosmetic composition comprising a silicone.

The alkyl groups have, for example, from 1 to 20 carbon atoms; the cycloalkyl groups have, for example, 5 or 6 carbon atoms; aryl groups are particularly phenyl groups; the alkylaryl groups may have from 7 to 20 carbon atoms. More particularly R2 denotes methyl. 25 n is an integer such that the polysiloxane of '- ^^ "•'" • - "'^ - Ha-ÜiÉaáÉ-h-dHI-B ..... ....

(b) and at least one silicone compound comprising at least one and at most two groups capable of reacting with the Rl groups of the polysiloxane (a), at least one of the compounds of type (a) or (b) contains an aliphatic group having an ethylenic unsaturation The compounds of type (b) are another polysiloxane of type (a) in the which groups Rl of the polysiloxane (b) are capable of reacting with the Rl groups of the polysiloxane (a) Preferably, the silicone copolymers are obtained in particular by addition reaction, in the presence of a hydrosilylation catalyst (for example a platinum), of at least: - (a) an alpha, omega-divinylpolydimeti lsiloxane, and - (b) an alpha, omega-dihydrogen polydimethylsiloxane.

This emulsion can be stabilized by a usual emulsifier system. This silicone emulsion may have a size of droplets or silicone particles between 10 nm and 50 μm, and preferably between 0.3 μm and 20 μm. The size of the particles is measured by laser granulometry. The emulsifier system comprises surfactants commonly used in silicone emulsions. These surfactants can be non-ionic, cationic, anionic or amphoteric or their mixtures such as those described below. The emulsifier system represents 0.5% to 10% by weight relative to the total weight of the emulsion. The synthesis of these silicone emulsions is described in particular in EP-A-10 874017. Such emulsions are sold in particular under the name DC2-1997 cationic emulsion by the company Dow Corning. This emulsion comprises a copolymer, w-15 divinyldimethicone /, ts-dihydrogenodimethicone with a dynamic viscosity of about 15,106 cP, a cationic emulsifier such as cetyltrimethylammonium chloride, a stabilizer of the hydroxyethylcellulose type and water. The silicone copolymer is preferably used in an amount between 0.05 and 10% by weight relative to the total weight of the composition. More preferably, this amount is between 0.1 and 5% by weight with respect to the total weight of the composition. ^^ t-M-i-i-Éi-á-a-ia- -.
