(57) [Summary] [Problem] To provide a resin composition for cosmetics and a cosmetic capable of simultaneously satisfying a plurality of properties required for cosmetics by using a resin having two or more properties. I do. SOLUTION: It has a structural unit derived from a compound having an ethylenically unsaturated bond, and has a number average molecular weight of 1.0 × 10 3 to 1.0 × 10 3 . A resin composition for cosmetics containing a block copolymer of 1.0 × 10 6 and having at least two or more glass transition points or melting points, and a cosmetic using the same. Preferably, the resin composition for cosmetics in which the block copolymer has at least one block composed of a structural unit having a hydrophilic group, and a cosmetic using the same. |
