Abstract:
A cosmetic preparation containing a crosslinkable silicone rubber emulsion comprising (A) 100 parts by weight of a straight chain or branched organopolysiloxane containing at least two hydroxyl groups bonded to the silicon atom per molecule prepared by ring-opening polymerization of a cyclic organosiloxane in the presence of an alkoxysilane or its partial hydrolytic condensate or an α,ω-dihydroxy or dialkoxy siloxane oligomer by using a catalyst selected from citric, lactic, and ascorbic acids and an anionic surfactant emulsifier; and (B) 0.5 to 20 parts by weight of a reaction product of an amino group-containing organoxysilane and an acid anhydride.
