| abstract |
The invention concerns a cosmetic composition comprising at least a functionalised organopolysiloxane of formula (I) or (I'): (R?1)(R2)(R3¿)Si-O-[Si(R4)(Z)-O]¿n?-[Si(R?5)(R6)-O]¿m-Si(R?7)(R8)(R9¿) where in formula (I), m ranges between 0 and 5, n ranges between 0 and 5, at least one of the radicals R?1 and R9¿ representing Z when n is equal to 0; in formula (I'), n ranges between 1 and 5, m ranges between 1 and 5, with n+m equal to at least 3; in formulae (I) and (I') R?1 and R9¿ are identical or different and represent Z or an alkyl radical; R?2, R3, R4, R5, R6, R7 and R8¿ are identical or different and represent an alkyl radical; Z represents a halogenoaliphatic radical, an -X-Y radical, where X represents a polyvalent aliphatic group and Y represents: an aryl radical optionally substituted by an alkyl, aryl group or a halogen atom; an ethylenically unsaturated cycloaliphatic radical optionally substituted by an alkyl group or a halogen atom; a saturated cycloaliphatic radical optionally substituted by a halogen atom; a hydrocarbon heterocyclic radical containing at least one hetereoatom N and/or O and/or S, radical optionally substituted by an alkyl, aryl group or a halogen atom; said symbol Z further capable of representing a phenyl radical when n+m is equal to 0. Said functionalised organotrisiloxane function is used as emollient and/or carrier and/or anti-transfer agent in cosmetic compositions. |
