Abstract:
1. A cosmetic composition which comprises the following Components (A) to (E) (A) 7 to 30% by weight of one or more non-volatile oil agents having a kinematic viscosity of 5 to 1000 mm (B) 0.2 to 5% by weight of one or more water-repellent resin powders whose particle size of the primary particle is in the range of 2 to 20 μm, wherein the water-repellent resin powder is selected from an organopolysiloxane elastomer spherical powder, a silicone resin-treated organopolysiloxane elastomer spherical powder, polymethylsilsesquioxane and polyalkylsilsesquioxane; (C) 0.1 to 6% by weight of one or more oil-soluble silicone resins selected from the group consisting of perfluoroalkyl group-containing polyalkylsiloxysilicate; (D) 20 to 60% by weight of one or more volatile solvents, excluding water, selected from the group consisting of cyclic tetra- to hexamer of dimethylpolysiloxane, branched tetramer of dimethylpolysiloxane (methyl trimethicone), linear dimethylpolysiloxane and a lower alcohol; wherein the volatile solvent(s) contains (contain) at least one volatile solvent whose boiling point at 1 atmosphere is 200° C. or lower; (E) 12 to 30% by weight of one or more water-repellent surface treated pigments, wherein the water-repellent surface treated pigment is selected from pigments subjected to silane treatment with organosilane having an alkyl group with carbon numbers of 6 to 20 which may be substituted and pigment subjected to silicone treatment; and (F) a highly polymerized silicone represented by the following general formula: wherein R1 represents a methyl group or a phenyl group, and R2 represents a methyl group or a hydroxyl group, provided that the case where all of R1 are phenyl groups is excluded, n represents an integer of 2,000 to 20,000.
