ANHYDROUS SUNSCREEN COMPOSITIONS COMPRISING AN ACID-CONTAINING FILM FORMING POLYMER AND AN ORGANIC AMINE

The invention provides a sprayable anhydrous sunscreen composition comprising at least one UV absorbing active ingredient and at least one film forming polymer containing a plurality of acid groups and a volatile solvent, wherein at least a portion of the acid groups have been neutralized with a cosmetically acceptable amine-based neutralizing agent: (see formula I) (see formula II) (see formula III) (see formula IV) (see formula V) or (see formula VI) wherein R6, R7, R8, R9, R10 R11, R12 x, y, z, and n are as defined herein. The invention further provides methods of using the above defined composition for increasing the SPF for an anhydrous composition, reducing the deleterious effects of UV radiation, for preventing or reducing the occurrence of erythema on a subject or for preventing or reducing photoaging of the skin of a subject due to exposure to UV radiation, or for preventing or reducing the occurrence of phototoxic or photoallergic reactions in a subject due to exposure to UV radiation.
