Claim:
Silicone microparticles, comprising 100 parts by mass of silicone elastomer spherical microparticles having a volume average particle diameter within a range from 0.1 to 100 μm, and 0.5 to 25 parts by mass of a polyorganosilsesquioxane that coats a surface of the silicone elastomer spherical microparticles, wherein the silicone elastomer is capable of absorbing not less than 30 parts by mass of at least one oily substance selected from the group consisting of sebum, hydrocarbon oils and ester oils per 100 parts by mass of the silicone elastomer, wherein the silicone elastomer is a cured product of a liquid silicone composition comprising: (A) (A1) an organohydrogenpolysiloxane having two hydrogen atoms bonded to silicon atoms within each molecule, represented by an average composition formula (1): R 1 a H b SiO (4−a−b)/2 (1) wherein R 1 represents an unsubstituted or substituted monovalent hydrocarbon group of 1 to 30 carbon atoms excluding aliphatic unsaturated groups, and a and b are positive numbers that satisfy 0 <a <3, 0 <b ≦3 ,and 0.1 ≦a+b ≦3, (A2) an organohydrogenpolysiloxane represented by the average composition formula (1) and having at least three hydrogen atoms bonded to silicon atoms within each molecule, or a combination of (A1) and (A2), (B) (B1) an organopolysiloxane having two monovalent olefinic unsaturated groups within each molecule, represented by an average composition formula (2): R 2 c R 3 d SiO (4−c−d)/2 (2) wherein R 2 represents an unsubstituted or substituted monovalent hydrocarbon group of 1 to 30 carbon atoms excluding aliphatic unsaturated groups, R 3 represents a monovalent olefinic unsaturated group of 2 to 6 carbon atoms, and c and d are positive numbers that satisfy 0 <c <3, 0 <d <3, and 0.1 <c+d <3, (B2) an organopolysiloxane represented by the average composition formula (2) and having at least three monovalent olefinic unsaturated groups within each molecule, or a combination of component (B1) and component (B2), in an amount that yields from 0.5 to 2 monovalent olefinic unsaturated groups within component (B) per hydrogen atom bonded to a silicon atom within component (A), and (C) a platinum group metal-based catalyst, wherein from 5 to 70 mol% of at least one of R 1 of formula (1) and R 2 of formula (2) are monovalent hydrocarbon groups of 6 to 30 carbon atoms, provided that when component (A) is component (A1), component (B) is either component (B2) or a combination of component (B1) and component (B2).
