Abstract
Cosmetic comprising (A) a specific acryl-silicone graft copolymer having an organosiloxane side chain is disclosed. The copolymer is prepared by radical polymerization of (i) a dimethylpolysiloxane compound having a polymerizable radical group on one of the molecular chain terminals and (ii) a radically polymerizable monomer comprising as major components an acrylate or methacrylate, or both. Various cosmetics including makeup cosmetics, o/w emulsion cosmetics, and w/o emulsion cosmetics, are prepared by using the copolymer in combination with (B) a low-viscosity silicone oil, (C) a partially cross-linked organopolysiloxane polymeric compound, (D) a low-boiling-point oil, (E) a volatile solvent, (F) a cosmetic powder material, (G) a polyacrylic acid, (H) a volatile hydrocarbon, (I) a surface active agent, or (J) water. The cosmetic compositions give a good sensation upon use, and exhibit superior water-repellency, water-resistance, oilresistance, and good retentiveness of the makeup.
