Patent ID: 8277791

Claim:
A cosmetic composition comprising a synergistic combination of: (i) a silicone polyurethane polymer comprising alternating units of A and B, where: unit A has the structure: wherein R is selected, independently at each occurrence from optionally substituted, branched, straight chain, or cyclic alkyl, alkenyl, alkynyl, aryl, alkyl-aryl, aryl-alkyl groups having from 1 to 10 carbon atoms, or R a group -L-O— thereby introducing branching points in unit A; and L is a linker group selected from optionally substituted-branched, straight chain, or cyclic divalent alkyl, alkenyl, alkynyl, aryl, alkyl-aryl, or aryl-alkyl groups having from 1 to 10 carbon atoms, and n is an integer from 0 to 5,000, and unit B has the structure: wherein R 1 is and optionally substituted, branched, straight chain, or cyclic alkenyl, alkynyl, aryl, alkyl-aryl, or aryl-alkyl groups having from 1 to 20 carbon atoms; and wherein units A and B form a cyclic polymer of the form where z is an integer from 2 to 2,000; and an elastomeric component comprising one or more elastomers selected from the group consisting of silicone gums, polyisobutylene, natural rubbers, and block-copolymer rubbers; wherein said synergistic combination comprises a weight ratio of silicone polyurethane polymer to elastomeric component from about 50:1 to about 1:50; and where said synergetic combination provides an improvement in one or more characteristic selected from the group consisting of water transfer resistance, oil transfer resistance, durability, and rheology.
