Abstract
A copolymer for cosmetics, which is obtained by polymerizing (A) 5 to 95% by weight of a fluorine-containing (meth)acrylate, and (B) 5 to 95% by weight of at least one fluorine-free monomer selected from the group consisting of (i) a silicone macromonomer, (ii) a polyalkylene glycol (meth)acrylate, (iii) an alkyl (meth)acrylate, and (iv) an alkyl (meth)acrylate macromonomer, can be easily incorporated in cosmetics and can form a film excellent in water resistance, water- and oil-repellency, feeling when used, and safety. This copolymer for cosmetics can improve the drawbacks of powder treated with a fluorine-containing compound.
