US4776855A — Hair dyeing process and composition

Claim 1

Independent Claim 129 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 C 16 to C 22 carboxylic acid and a polyalkylene glycol ether of a C 16 to C 22 alcohol and two or more monomers of C 16 to C 22 carboxylic acid or their esters, and 1 to 10% by weight of a peroxide at a pH of about 1.5 to 5.5.

Claim 2

Dependent Claim 129 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 C 16 to C 22 carboxylic acid and a polyalkylene glycol ether of a C 16 to C 22 alcohol and two or more monomers of C 16 to C 22 carboxylic acid or their esters, and 1 to 10% by weight of 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 26 words

The 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.

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 67 words

The composition according to claim 3 wherein the first part further contains an amount of a solvent sufficient to solubilize the hair dye intermediate up to about 20%; said solvent selected from the group consisting of hexylene glycol, propylene glycol, diethylene glycolmonoethyl ether 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 7

Dependent Claim 32 words

The composition according to claim 2 wherein said first part contains 2% hexylene glycol, 4% diethyleneglycolmonoethyl ether, 5.77% ammonia (28%) 2.84% ammonium chloride, 2% sodium lauryl sulfate (30%), and 0.2% sodium chloride.

Claim 8

Dependent Claim 25 words

The composition according to claim 2 wherein said second part contains 10% acrylates/streareth-20 methacrylate copolymer, 12.3% hydrogen peroxide (50%), and 0.04% phenacetin and 0.02% EDTA.

Claim 9

Independent Claim 159 words

A method for oxidation dyeing of human hair comprising admixing an aqueous lotion containing a tinctorially effective amount of an oxidation hair dye intermediate, and an alkaline material in an amount sufficient to provide a final pH of about 8 to 12 when admixed with an aqueous developer; and an aqueous developer containing about 0.04 to 25% by weight of a polymer of an ester of a C 16 to C 22 carboxylic acid and a polyalkylene glycol ether of a C 16 to C 22 alcohol and two or more monomers of C 16 to C 22 carboxylic acid or their esters, and 1 to 10% by weight of a peroxide at a pH of about 1.5 to 5.5; the lotion and the developer being thin emulsions which upon said admixing thicken to produce a thickened emulsion; then applying the thickened emulsion to the hair for a period of time sufficient for the dyeing process to take place.

Claim 10

Independent Claim 159 words

A method for oxidation dyeing of human hair comprising admixing an aqueous lotion containing a tinctorially effective amount of an oxidation hair dye intermediate, and an alkaline material in an amount sufficient to provide a final pH of about 8 to 12 when admixed with an aqueous developer; and an aqueous developer containing about 0.04 to 25% by weight of a polymer of an ester of a C 16 to C 22 carboxylic acid and a polyalkylene glycol ether of a C 16 to C 22 alcohol and two or more monomers of C 16 to C 22 carboxylic acid or their esters, and 1 to 10% by weight of a peroxide at a pH of about 1.5 to 5.5; the lotion and the developer being thin emulsions which upon said admixing thicken to produce a thickened emulsion; then applying the thickened emulsion to the hair for a period of time sufficient for the dyeing process to take place.

Claim 11

Dependent Claim 21 words

The method according to claim 8 wherein the aqueous developer contains an aqueous emulsion of hydrogen peroxide and acrylates/steareth-20 methacrylate copolymer.
