Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 92 words
As a novel composition of matter, a benzene sulfonate quaternary salt of an organic sunscreen carboxylic acid corresponding to the formula: ##STR2## wherein the R is an acyl derived from the group consisting of p-amino benzoyl, p-dimethyl amino benzoyl, p-methoxy cinnamoyl, p-methoxy benzal, and cinnamal malonoyl; R' is an alkyl group having from 1 to 2 carbon atoms; R" is an alkyl group having from 10 to 20 carbon atoms; R'" is selected from the group consisting of H and CH 3 ; and Y is an integer of 0 to 1.
Claim 2
Dependent Claim 92 words
As a novel composition of matter, a benzene sulfonate quaternary salt of an organic sunscreen carboxylic acid corresponding to the formula: ##STR2## wherein the R is an acyl derived from the group consisting of p-amino benzoyl, p-dimethyl amino benzoyl, p-methoxy cinnamoyl, p-methoxy benzal, and cinnamal malonoyl; R' is an alkyl group having from 1 to 2 carbon atoms; R" is an alkyl group having from 10 to 20 carbon atoms; R'" is selected from the group consisting of H and CH 3 ; and Y is an integer of 0 to 1.
Claim 3
Dependent Claim 44 words
The composition of claim 1 selected from the group consisting of cetyl/stearyl p-toluene sulfonate quaternary of 2-dimethyl amino ethyl p-dimethyl amino benzoate; cetyl/stearyl p-toluene sulfonate quaternary of 2-dimethyl amino ethyl p-methoxy cinnamate; and di-cetyl stearyl p-toluene sulfonate quaternary of di-(2-dimethyl amino ethyl)p-methoxy benzal malonate.
Claim 4
Dependent Claim 114 words
A composition adapted for application to human hair comprising a cosmetic carrier containing an effective amount, sufficient to provide substantial protection from the effects of sunlight of a benzene sulfonate quaternary salt of an organic sunscreen carboxylic acid corresponding to the formula ##STR3## wherein the R is an acyl derived from the group consisting of p-amino benzoyl, p-dimethyl amino benzoyl, p-methoxy cinnamoyl, p-methoxy benzal malonoyl, and cinnamal malonoyl; R' is an alkyl group having from 1 to 2 carbon atoms; R" is an alkyl group having from 10 to 20 carbon atoms; R'" is selected from the group consisting of H and CH 3 ; and Y is an integer of 0 to 1.
Claim 5
Dependent Claim 114 words
A composition adapted for application to human hair comprising a cosmetic carrier containing an effective amount, sufficient to provide substantial protection from the effects of sunlight of a benzene sulfonate quaternary salt of an organic sunscreen carboxylic acid corresponding to the formula ##STR3## wherein the R is an acyl derived from the group consisting of p-amino benzoyl, p-dimethyl amino benzoyl, p-methoxy cinnamoyl, p-methoxy benzal malonoyl, and cinnamal malonoyl; R' is an alkyl group having from 1 to 2 carbon atoms; R" is an alkyl group having from 10 to 20 carbon atoms; R'" is selected from the group consisting of H and CH 3 ; and Y is an integer of 0 to 1.
Claim 6
Dependent Claim 49 words
The composition of claim 3 in which the salt is selected from the group consisting of cetyl-stearyl p-toluene sulfonate quaternary of 2-dimethyl amino ethyl p-dimethyl amino benzoate; cetyl/stearyl p-toluene sulfonate quaternary of 2-dimethyl amino ethyl p-methoxy cinnamate; and di-cetyl stearyl p-toluene sulfonate quaternary of di(2-dimethyl amino ethyl)p-methoxy benzal malonate.
