Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
138 words
A hair conditioning product which is a member selected from the group consisting of shampoos, conditioners, creme rinses, and setting gels and containing an effective amount of a polymer for imparting good conditioning properties to hair made from ethylenically unsaturated addition polymerizable monomers and containing units of a member selected from the group consisting of a pendant primary amino group of the following structure: ##STR13## where: =an organic polymer chain; R=H, alkyl, aryl, --COOH, --COOR" or --CONH 2 , and R"--methyl, ethyl or other lower alkyl; an ammonium salt of said amine group of the following structure: ##STR14## where: =an organic polymer chain, R=H, alkyl, aryl, --COOH, --COOR" or --CONH 2 , and R"=methyl, ethyl or other lower alkyl, and - X=halide, hydroxide, methyl sulfate, or similar negatively charged group; or admixtures of the amino group and salt.
Claim 2
Dependent Claim
138 words
