Enhanced efficiency of sunscreen compositions

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 the polymer is present in an amount greater than 1% by weight of the composition and wherein at least a portion of the acid groups have been neutralized with a cosmetically acceptable neutralizing agent and the SPF of the sprayable anhydrous sunscreen composition is greater than 125% of a composition containing un-neutralized film forming polymer, wherein the amine-based neutralizing agent is selected from an agent having the structure:

• wherein R8 is C2 to about C36 straight chain, branched or cyclic alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, or aralkynyl group, and R9 is selected from H or CH3, or C2 to C36 straight chain, branched or cyclic alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, or aralkynyl group, and wherein x and y are independently 1 to 100 and wherein said amine based agent can optionally contain one or more heteroatoms;
• wherein R10 R11, and R12 are independently selected from H, CH3 or C2 to about C36 straight chain, branched or cyclic alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, or aralkynyl group, and wherein n is 1 to 100 and wherein said amine based agent can optionally contain one or more heteroatoms;
• wherein R6 is H or CH3 and x and y are independently from about 1 to about 100;
• wherein x is from about 1 to about 100;
• wherein x, y and z are independently from about 1 to about 100;
• and
• wherein R7 is H or C2H5 and n, x, y and z are independently from about 1 to about 100;
• wherein the solvent is selected from ethanol, isopropanol, methanol or acetone.
