(57) [Summary] [Structure] The following groups directly bonded to a silicon atom: -R 1- X, -R 2 -Si (R 3 ) 3-a - (OR 4) a and - (CH 2) l -O- (C 2 H 4 O) m - (C 3 H 6 O) n -R 5 (wherein, R 1 = a direct bond, divalent hydrocarbon radical, R 2 = alkylene group, R 3 , R 4 = alkyl group, R 5 = H, acyl group, monovalent hydrocarbon group, X = organic reactive group, a = 2,3, l = 0, positive integer, m, n = 0-150), and an inorganic powder surface-treated with a reactive organopolysiloxane, and a cosmetic containing the same. [Effect] This cosmetic has durability, water resistance, compatibility with skin, It has excellent gloss, water repellency, flexibility, water vapor permeability, gas permeability, lubricity, dispersibility in oil, retention of filler, film forming property, product stability, and usability (extendability). Is extremely high. |
