Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
98 words
A method of promoting the growth of normal dermal and epidermal tissue in mammals which comprises topical treatment of a mammal in need of such promotion with a composition comprising from 25 to 40% by weight of a mixture containing thioglycolic acid and 65% to 85% dilute ammonium hydroxide at a pH of from 8.5 to 11 together with: Glycerine: 0.15 to 0.25% Citric Acid: 0.095 to 0.29% Hydrogen Peroxide: 0.0097 to 0.014% Solvent: 0.39 to 0.78% Lower Alkanol: 0.78 to 1.95% Gelatin: 1.17 to 2.73% and water, all percentages pased on the total weight of the composition.
Claim 2
Independent Claim
98 words
A method of promoting the growth of normal dermal and epidermal tissue in mammals which comprises topical treatment of a mammal in need of such promotion with a composition comprising from 25 to 40% by weight of a mixture containing thioglycolic acid and 65% to 85% dilute ammonium hydroxide at a pH of from 8.5 to 11 together with: Glycerine: 0.15 to 0.25% Citric Acid: 0.095 to 0.29% Hydrogen Peroxide: 0.0097 to 0.014% Solvent: 0.39 to 0.78% Lower Alkanol: 0.78 to 1.95% Gelatin: 1.17 to 2.73% and water, all percentages pased on the total weight of the composition.
Claim 3
Dependent Claim
11 words
