Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A method of treating skin and hair with a self-heated cosmetic composition devoid of any substance capable of reaction with the boron compound defined below and selected from the group consisting of skin cleaner, skin cream, skin lotion, shampoo, shaving preparation and after-shave preparation comprising contacting the skin and hair, in the presence of water, with said composition containing about 20 to about 80% by weight of a boron compound of the formula: ##STR17## wherein R 1 , R 2 , R 3 and R 4 are individually C 2-8 alkyl, acetyl, mononuclear aryl, mononuclear aralkyl, mononuclear aroyl, cycloalkyl, or an ethoxylated derivative thereof, or R 1 and R 3 collectively or R 2 and R 4 collectively are: ##STR18## to collectively form cyclic compounds.
Claim 2
Independent Claim
125 words
A method of treating skin and hair with a self-heated cosmetic composition devoid of any substance capable of reaction with the boron compound defined below and selected from the group consisting of skin cleaner, skin cream, skin lotion, shampoo, shaving preparation and after-shave preparation comprising contacting the skin and hair, in the presence of water, with said composition containing about 20 to about 80% by weight of a boron compound of the formula: ##STR17## wherein R 1 , R 2 , R 3 and R 4 are individually C 2-8 alkyl, acetyl, mononuclear aryl, mononuclear aralkyl, mononuclear aroyl, cycloalkyl, or an ethoxylated derivative thereof, or R 1 and R 3 collectively or R 2 and R 4 collectively are: ##STR18## to collectively form cyclic compounds.
Claim 3
Dependent Claim
23 words
A method as defined in claim 1 wherein said boron compound is a tri (C 2-8 alkoxy) boroxine or bis (ethylene glycol) diborate.
Claim 4
Dependent Claim
14 words
A method as defined in claim 2 wherein said boron compound is triethoxy boroxine.
Claim 5
Dependent Claim
19 words
A method as defined in claim 1 wherein said composition contains an organic anionic, nonionic, cationic or amphoteric surfactant.
Claim 6
Dependent Claim
14 words
A method as defined in claim 1 wherein said composition is a shaving preparation.
Claim 7
Dependent Claim
16 words
A method as defined in claim 5 wherein said composition contains a liquified normally gaseous propellant.
Claim 8
Dependent Claim
32 words
A method as defined in claim 1 wherein such skin or hair is first wetted with water and said composition containing said boron compound is applied to the wet skin or hair.
Claim 9
Dependent Claim
29 words
A method as defined in claim 1 wherein said composition containing said boron compound is intimately mixed with the water immediately prior to contacting the skin or hair therewith.
