Use of alkyl dimethicone copolyol type silicone surfactants in the preparation of solid cosmetic water-in-oil emulsions and the resulting solid water-in-oil emulsions

摘要

The present invention relates to the use of a silicone surfactant of alkyl dimethicone copolyol type of formula: in which: PE=(-CSUB2/SUBHSUB4/SUBO)SUBx/SUB(-CSUB3/SUBHSUB6/SUBO)SUBy/SUB-H, x=0 to 50, y=0 to 30, x and y not simultaneously being 0, o=1 to 100, m=1 to 40, n=1 to 200, p=1 to 17 and q=1 to 5, in the preparation of a solid water-in-oil emulsion comprising an aqueous phase emulsified by the said surfactant in a fatty phase comprising at least one oil and at least one wax. The invention also relates to a solid emulsion of water-in-oil type, in particular a transfer-free foundation, such as the emulsion defined above.
