Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 117 words
A two part composition for hair treating when combined, wherein the two parts are intended to be admixed with each other shortly before use, which comprises a) an aqueous first part containing an alkaline material in an amount sufficient to provide a final pH of about 8 to 12 when admixed with a second part; and b) an aqueous second part containing about 0.04 to 25% by weight of a polymer of an ester of a C₁₆ to C₂₂ carboxylic acid and a polyalkylene glycol ether of a C₁₆ to C₂₂ alcohol and two or more monomers of C₁₆ to C₂₂ carboxylic acid or their esters, and a peroxide at a pH of about 1.5 to 5.5.
Claim 2
Dependent Claim 117 words
A two part composition for hair treating when combined, wherein the two parts are intended to be admixed with each other shortly before use, which comprises a) an aqueous first part containing an alkaline material in an amount sufficient to provide a final pH of about 8 to 12 when admixed with a second part; and b) an aqueous second part containing about 0.04 to 25% by weight of a polymer of an ester of a C₁₆ to C₂₂ carboxylic acid and a polyalkylene glycol ether of a C₁₆ to C₂₂ alcohol and two or more monomers of C₁₆ to C₂₂ carboxylic acid or their esters, and a peroxide at a pH of about 1.5 to 5.5.
Claim 3
Dependent Claim 20 words
The composition according to claim 1 wherein said polymer is acrylates/steareth 20 methacrylate copolymer and said peroxide is hydrogen peroxide.
Claim 4
Dependent Claim 39 words
A two part hair treating composition according to claim 2 wherein the first part further contains a tinctorially effective amount of an oxidation hair dye intermediate and an aqueous dye solvent in an amount sufficient to solubilize the dye.
Claim 5
Dependent Claim 36 words
The composition according to claim 2 wherein said second part is combined just prior to mixing with said first part from two sub-parts, one containing the acrylate/steareth 20 methacrylate copolymer and the other the hydrogen peroxide.
Claim 6
Dependent Claim 35 words
The composition according to claim 3 wherein the aqueous dye solvent in the first part is selected from the group consisting of water, hexylene glycol, propylene glycol, Carbitol or mixtures of two or more thereof.
Claim 7
Dependent Claim 58 words
A two part composition according to claim 3 wherein said first part contains 0 to about 20% of an aqueous dye solvent selected from the group consisting of water, hexylene, glycol, propylene glycol, Carbitol, and mixtures of two or more thereof, and said second part further contains 0 to about 0.2% phenacetin, and 0 to about 0.1% EDTA.
Claim 8
Dependent Claim 31 words
The composition according to claim 2 wherein said first part contains 2% hexylene glycol, 4% Carbitol, 5.77% ammonia (28%) 2.84% ammonium chloride, 2% sodium lauryl sulfate (30%), and 0.2% sodium chloride.
Claim 9
Dependent Claim 25 words
The composition according to claim 2 wherein said second part contains 10% acrylates/steareth-20 methacrylate copolymer, 12.3% hydrogen peroxide (50%), and 0.04% phenacetin and 0.02% EDTA.
Claim 10
Independent Claim 60 words
A method for oxidation dyeing of human hair comprising admixing the two components of a two part system having a lotion part and a developer part in which each part is a thin emulsion which upon said admixing, thickens, and thereafter applying said thickened emulsion to hair for a period of time sufficient for the dyeing process to take place.
Claim 11
Independent Claim 60 words
A method for oxidation dyeing of human hair comprising admixing the two components of a two part system having a lotion part and a developer part in which each part is a thin emulsion which upon said admixing, thickens, and thereafter applying said thickened emulsion to hair for a period of time sufficient for the dyeing process to take place.
Claim 12
Dependent Claim 20 words
The method of claim 9 wherein said developer part contains an aqueous emulsion of hydrogen peroxide and acrylates/steareth-20 methacrylate copolymer.
