Abstract:
1. A cosmetic resin composition consisting essentially of an amphoteric urethane resin having a carboxyl group and a tertiary amino group in one molecule thereof, the amphoteric urethane resin having polysiloxane linkage in its structure, wherein the amphoteric urethane resin is obtained by reacting the following components (A) to (D) in excess of isocyanate groups so as to produce a prepolymer containing isocyanate groups and reacting the prepolymer with the following component (E); (A) one or more polyol compounds selected from the group consisting of polyester polyol, polyether polyol, polycarbonate polyol, polybutadiene polyol, polyisoprene polyol, polyolefin polyol, polyacrylic ester polyol and combinations thereof, wherein the one or more polyol compounds are not formed from α,β ethylenically unsaturated carboxylic acids; (B) a polyisocyanate compound; (C) a polysiloxane compound having an active hydrogen; (D) a compound having an active hydrogen and a carboxyl group; (E) a compound having an active hydrogen and a tertiary amino group.
