Patent ID: 8128913

Claim:
A sunscreen composition comprising: (a) a skin bonding polymer composition comprising a hydrophobic polymer/hydrophilic polymer adduct, wherein the hydrophobic polymer/hydrophilic polymer adduct comprises: (i) a hydrophobic polymer composition comprising a mixture of a lower poly(vinylpyrrolidone/alkylene) polymer wherein the alkylene group contains 10 to 24 carbon atoms and a higher poly(vinylpyrrolidone/alkylene) polymer wherein the alkylene group contains about 30 carbon atoms; and (ii) a hydrophilic polymer composition comprising poly(maleic acid/methylvinylether) copolymer having a weight average molecular weight of at least 50,000; and (iii) wherein the weight ratio of the lower poly(vinylpyrrolidone/alkylene) polymer to the higher poly(vinylpyrrolidone/alkylene) polymer is about 10:1 to about 2:1; (b) sunscreen active agent comprising a UV-A absorber; and (c) water in an amount effective to provide the composition with a texture suitable for application to skin.
