Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
122 words
In a hair treating method for imparting curl retention to hair in which at least one film forming ingredient is applied to the hair, the improvement consisting essentially of applying to the hair a mixture of: (A) a silanol-end-blocked polydiorganosiloxane fluid represented by the formula ##STR4## wherein R 1 and R 2 are independently selected from the group consisting of hydrogen, alkyl, alkenyl, aryl, alkylaryl, aralkyl and organo-modified alkyl and aryl groups having 1 to 22 carbon atoms; n is an integer from 5 to 15,000; (B) an organosilicon crosslinking agent; and (C) a low molecular weight carrier; curling the mixture by contact with moisture to form an unfilled low strength silicon elastomer and utilizing the elastomer as the film forming ingredient.
Claim 2
Dependent Claim
122 words
In a hair treating method for imparting curl retention to hair in which at least one film forming ingredient is applied to the hair, the improvement consisting essentially of applying to the hair a mixture of: (A) a silanol-end-blocked polydiorganosiloxane fluid represented by the formula ##STR4## wherein R 1 and R 2 are independently selected from the group consisting of hydrogen, alkyl, alkenyl, aryl, alkylaryl, aralkyl and organo-modified alkyl and aryl groups having 1 to 22 carbon atoms; n is an integer from 5 to 15,000; (B) an organosilicon crosslinking agent; and (C) a low molecular weight carrier; curling the mixture by contact with moisture to form an unfilled low strength silicon elastomer and utilizing the elastomer as the film forming ingredient.
Claim 3
Dependent Claim
21 words
