(57) [Summary] [Purpose] To provide a skin cosmetic having excellent adhesion to the skin, having a long-lasting makeup, and having a light feeling. A copolymer obtained by copolymerizing N-vinylpyrrolidone and an organopolysiloxane compound having a radically polymerizable group at one end of a molecular chain represented by the following general formula (1), wherein: The ratio of N-vinylpyrrolidone in the polymer is more than 60 mol% in a molar ratio and 60 in a weight ratio. It is a skin cosmetic in which a copolymer of less than wt% is blended as an oil agent. Embedded image (In the formula, R 1 is a hydrogen atom or a methyl group; R 2 is 1 or 2; 1 to 10 carbon atoms, which may be interrupted by one or more oxygen atoms R 3 and R 4 are the same or different and are unsubstituted or substituted monovalent hydrocarbon groups having 1 to 18 carbon atoms or R. R is a polyorganosiloxane group. ) |
