Claim 1
Independent Claim
156 words
A method of treating hair on the head to reduce the time required for the drying thereof when wet, which comprises applying thereto in a cosmetically acceptable carrier suitable for application to human hair an effective amount of a vinyl polymer selected from the group consisting of homopolymers, copolymers, block copolymers and graft copolymers of a fluorine-containing monomer of the formula: ##STR4## wherein R 1 is an alkyl group containing 1 to 6 carbon atoms R 2 is hydrogen or methyl, and n is an integer from 3 to 11, the vinyl polymer having a molecular weight of from 20,000 to 1,000,000, and when the polymer is a copolymer, the ratio of the fluorine-containing monomer to the comonomer or comonomers being from 10:1 to 1:1 and said comonomer being selected from the group consisting of halogenated and non-halogenated maleic anhydride, acrylonitrile, vinyl acetate, vinyl chloride, vinyl silicones, styrene, methyl acrylate, methyl methacrylate, ethylene, isoprene and butadiene.
Claim 2
Independent Claim
156 words
A method of treating hair on the head to reduce the time required for the drying thereof when wet, which comprises applying thereto in a cosmetically acceptable carrier suitable for application to human hair an effective amount of a vinyl polymer selected from the group consisting of homopolymers, copolymers, block copolymers and graft copolymers of a fluorine-containing monomer of the formula: ##STR4## wherein R 1 is an alkyl group containing 1 to 6 carbon atoms R 2 is hydrogen or methyl, and n is an integer from 3 to 11, the vinyl polymer having a molecular weight of from 20,000 to 1,000,000, and when the polymer is a copolymer, the ratio of the fluorine-containing monomer to the comonomer or comonomers being from 10:1 to 1:1 and said comonomer being selected from the group consisting of halogenated and non-halogenated maleic anhydride, acrylonitrile, vinyl acetate, vinyl chloride, vinyl silicones, styrene, methyl acrylate, methyl methacrylate, ethylene, isoprene and butadiene.
Claim 3
Dependent Claim
19 words

Claim 6
Dependent Claim
32 words
The method defined in claim 1 wherein the said carrier is a hair cosmetic preparation selected from the group consisting of hair shampoo, waving, setting, bleaching, coloring, conditioning and hair dressing products.
