Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 58 words
A composition for decreasing hair hygroscopicity and thus imparting improved settability to keratin fibers, which comprises an aqueous solution containing a sufficient amount of heximinium salt and a sufficient amount of a resorcinol to form in situ in the keratin fibers a keratin fiber setting amount of a condensation polymer derived from said heximinium salt and said resorcinol.
Claim 2
Dependent Claim 58 words
A composition for decreasing hair hygroscopicity and thus imparting improved settability to keratin fibers, which comprises an aqueous solution containing a sufficient amount of heximinium salt and a sufficient amount of a resorcinol to form in situ in the keratin fibers a keratin fiber setting amount of a condensation polymer derived from said heximinium salt and said resorcinol.
Claim 3
Dependent Claim 68 words
The composition of claim 1 wherein the heximinium salt has the formula [C 6 H 12 N 4 R 1 ]X and the resorcinol has the formula ##STR5## R 1 is a substituted or unsubstituted straight or branched chain alkyl, aryl, aralkyl or olefinic group containing up to 18 carbon atoms, X is a halide, and R 2 is hydrogen or alkyl having 1 to 12 carbon atoms.
Claim 4
Dependent Claim 16 words
A composition according to claim 2 wherein R 1 contains from 2 to 18 carbon atoms.
Claim 5
Dependent Claim 77 words
