COSMETIC EMULSION COMPOSITIONS CONTAINING A VINYL DIMETHICONE / DIMETHICONE COPOLYMER AND A CATIONIC SURFACE AND ITS APPLICATIONS

摘要

Cosmetic composition contains an emulsion(s) comprising a silicone copolymer(s) obtained by reacting a polysiloxane (I) and a silicone compound(s) with at least two groups reactive with the terminal groups of (I) using a catalyst. Cosmetic composition comprises a cosmetically acceptable medium, a cationic surfactant(s) and an emulsion(s) comprising a silicone copolymer of viscosity 106 to 108 cP obtained by reacting a polysiloxane (A) of formula (I) and a silicone compound(s) (B) with at least two groups reactive with the terminal groups of (I) using a catalyst, at least one of (A) and (B) containing one or two ethylenically unsaturated aliphatic groups: R1-Si(R2)2-(-O-Si(R2)2-)n-O-Si(R2)2-R1 (I) R1 = H or ethylenically unsaturated group, particularly vinyl, allyl or hexenyl; R2 = 1-20C alkyl, 5-6C cycloalkyl, 7-20C aralkyl or OH optionally with ether, amino, carboxyl, hydroxyl, thiol, ester, sulfonate or sulfate groups; and n = number giving a viscosity of 1 to 106 mm2/s.
