Abstract
Abstract Sunscreening compositions and methods for using the same to protect human skin from erythema producing ultraviolet radiation by applying to the skin a cosmetic carrier composition containing an effective amount to substantially prevent erythema of a cationic para-amino benzoate ester of a substituted amino alkanol. Sunscreening compositions containing cationic para-amino benzoates when applied to the skin have been found to be substantially uneffected by moisture from perspiration or swimming and are, therefore, substantive in form.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
168 words
A method of protecting human skin from erythema producing ultraviolet radiation which comprises applying to said skin a composition of a cosmetic carrier containing from about 1-10 percent by weight based on the total weight of the composition of a cationic aminobenzoate having the general formula: ##STR5## wherein Y is a amino radical having the formula ##STR6## such that R 1 and R 2 are each selected from the group consisting of C 1 -C 5 alkyl, aryl, alkaryl, substituted alkyl, substituted aryl, and substituted alkaryl; wherein Z is a bivalent alkyl hydrocarbon containing from 1 to 5 carbon atoms; wherein X is an anion selected from the group consisting of chloro, bromo, fluoro, iodo, sulfate, bisulfate, carbonate, bicarbonate, sulfite, and bisulfite; wherein R 6 , R 7 , R 8 and R 9 are selected from the group consisting of alkyl, aryl, and alkaryl; wherein A is a bivalent C 1 -C 20 hydrocarbon bridging radical and wherein a and b are the integers 1 or 2.
Claim 2
Independent Claim
168 words
A method of protecting human skin from erythema producing ultraviolet radiation which comprises applying to said skin a composition of a cosmetic carrier containing from about 1-10 percent by weight based on the total weight of the composition of a cationic aminobenzoate having the general formula: ##STR5## wherein Y is a amino radical having the formula ##STR6## such that R 1 and R 2 are each selected from the group consisting of C 1 -C 5 alkyl, aryl, alkaryl, substituted alkyl, substituted aryl, and substituted alkaryl; wherein Z is a bivalent alkyl hydrocarbon containing from 1 to 5 carbon atoms; wherein X is an anion selected from the group consisting of chloro, bromo, fluoro, iodo, sulfate, bisulfate, carbonate, bicarbonate, sulfite, and bisulfite; wherein R 6 , R 7 , R 8 and R 9 are selected from the group consisting of alkyl, aryl, and alkaryl; wherein A is a bivalent C 1 -C 20 hydrocarbon bridging radical and wherein a and b are the integers 1 or 2.
Claim 3
Dependent Claim
26 words
The method of protecting the human skin according to claim 1 wherein the cosmetic carrier is an aliphatic alcohol containing from 1 to 5 carbon atoms.
Claim 4
Dependent Claim
31 words
The method according to claim 2 wherein the carrier is a hydroalcoholic solution of the aminobenzoate mixed with a carrier selected from the group consisting of oils, water-in-oil emulsions and creams.
Claim 5
Dependent Claim
17 words
The method according to claim 1 wherein the cationic benzoate composition is applied from an aerosol container.
Claim 6
Dependent Claim
171 words
The composition for providing longlasting protection to the human skin from erythema-causing ultraviolet radiation which comprises a cosmetic carrier material containing distributed therein from about 1 percent to about 10 percent based on the total weight of the composition of a cationic aminobenzoate having the general formula: ##STR7## wherein Y is a amino radical having the formula of ##STR8## such that R 1 and R 2 are each selected from the group consisting of C 1 -C 5 alkyl, aryl, alkaryl, substituted alkyl, substituted aryl and substituted alkaryl; wherein Z is a bivalent alkyl hydrocarbon containing from 1 to 5 carbon atoms; wherein X is an anion selected from the group consisting of chloro, bromo, fluoro, iodo, sulfate, bisulfate, carbonate, bicarbonate, sulfite, and bisulfite; wherein R 6 , R 7 , R 8 , and R 9 are selected from the group consisting of alkyl, aryl, and alkaryl; wherein A is a bivalent C 1 -C 20 alkyl hydrocarbon bridging radical and wherein a and b are integers 1 or 2.
Claim 7
Dependent Claim
171 words
The composition for providing longlasting protection to the human skin from erythema-causing ultraviolet radiation which comprises a cosmetic carrier material containing distributed therein from about 1 percent to about 10 percent based on the total weight of the composition of a cationic aminobenzoate having the general formula: ##STR7## wherein Y is a amino radical having the formula of ##STR8## such that R 1 and R 2 are each selected from the group consisting of C 1 -C 5 alkyl, aryl, alkaryl, substituted alkyl, substituted aryl and substituted alkaryl; wherein Z is a bivalent alkyl hydrocarbon containing from 1 to 5 carbon atoms; wherein X is an anion selected from the group consisting of chloro, bromo, fluoro, iodo, sulfate, bisulfate, carbonate, bicarbonate, sulfite, and bisulfite; wherein R 6 , R 7 , R 8 , and R 9 are selected from the group consisting of alkyl, aryl, and alkaryl; wherein A is a bivalent C 1 -C 20 alkyl hydrocarbon bridging radical and wherein a and b are integers 1 or 2.
