ABSTRACT:
Sunscreen compositions which are waterproof and have high-SPF values comprise a water insoluble film-forming polymer, a polyoxypropylene ether of straight or branched chain alcohol (the emollient/solvent) and a sunscreen component containing at least one UVB type sunscreen and/or at least one UVA type sunscreen in a topical vehicle, preferably in the form of an alcoholic gel. In particular, the combination of a polyoxyalkylene ether of a straight or branched chain alcohol, a carboxylated acrylic copolymer and a sunscreen agent yields waterproof, high-SPF compositions.
