Abstract
The polymer for cosmetics produced by polymerizing (A) a fluorine-containing (meth)acrylate, and (B) at least one silicon-containing polymerizable compound selected from the group consisting of a mercapto-modified silicone, an azo group-containing silicone and a polymerizable silane can be blended easily in cosmetic preparations and can form a film excellent in a water proofing property, a water- and oil-repellency, feelings in use and safety. This copolymer for cosmetics can improve the drawbacks of fluorine compound-treated powders.
