1. A film forming composition comprising at least one film forming polymer containing a plurality of acid groups, wherein at least a portion of the acid groups have been neutralized with a cosmetically acceptable neutralizing agent, wherein the film forming composition exhibits a boost to SPF in sunscreen compositions by 125% compared to the SPF of sunscreen compositions that do not include the film forming composition, wherein the cosmetically acceptable 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 straight chain, branched or cyclic alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, or aralkynyl groups 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 straight chain, branched or cyclic alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, or aralkynyl groups 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; andwherein R7 is H or C2H5 and n, x, y and z are independently from about 1 to about 100. |
