<P>PROBLEM TO BE SOLVED: To provide a copolymer that exhibits high setting properties and high re-styling properties and yet has a wide degree of freedom for formulations such as a spray, mist, wax and the like, and a composition for a cosmetic that comprises the copolymer. <P>SOLUTION: The copolymer comprises a constituting unit corresponding to a vinyl monomer (A) represented by general formula (1) and a constituting unit corresponding to a vinyl monomer (B) based on [an alkyl (meth)acrylate or an N-alkyl-(meth)acrylamide] represented by a specific formula, does not dissolve in water lower than 30°C and has a heat absorption initiation temperature between -25°C and 40°C when heated from a low temperature. The composition for a cosmetic comprises the copolymer. In general formula (1), R<SP POS="POST">1</SP>is a hydrogen atom or a 1-3C alkyl group: R<SP POS="POST">2</SP>is a 2-4C alkylene group; R<SP POS="POST">3</SP>is a hydrogen atom or a methyl group; and m is an integer of 1-100. <P>COPYRIGHT: (C)2012,JPO&INPIT |
