Abstract
Abstract A process for setting hair is disclosed comprising the steps of applying to the hair a solution of sulfonated polymer selected from the group consisting of sulfonated polystyrene, sulfonated interpolymers of styrene and ethylenically unsaturated comonomers, and soluble salts of said sulfonated polymers, setting the hair in the desired configuration, and allowing the hair to dry while it is retained in the desired configuration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A process for setting hair comprising the steps of: a. applying to the hair an effective amount of a solution of sulfonated polymer selected from the group consisting of a sulfonated polystyrene, a sulfonated interpolymer of styrene with a copolymerizable ethylenically unsaturated comonomer in a proportion of at least 50% styrene, by weight, and a soluble salt of said sulfonated polymers; and a solvent selected from the group consisting of water, ethanol, isopropanol and mixtures thereof, said sulfonated polymers having an average molecular weight of from about 6,000 to about 7,000,000 and being present in an amount of from about 0.1 to about 10.0%, by weight, of the total solution, b. fixing the hair in a desired configuration, and c. allowing the hair to dry while it is retained in said desired configuration.
Claim 2
Dependent Claim
133 words
A process for setting hair comprising the steps of: a. applying to the hair an effective amount of a solution of sulfonated polymer selected from the group consisting of a sulfonated polystyrene, a sulfonated interpolymer of styrene with a copolymerizable ethylenically unsaturated comonomer in a proportion of at least 50% styrene, by weight, and a soluble salt of said sulfonated polymers; and a solvent selected from the group consisting of water, ethanol, isopropanol and mixtures thereof, said sulfonated polymers having an average molecular weight of from about 6,000 to about 7,000,000 and being present in an amount of from about 0.1 to about 10.0%, by weight, of the total solution, b. fixing the hair in a desired configuration, and c. allowing the hair to dry while it is retained in said desired configuration.
Claim 3
Dependent Claim
