Abstract
Abstract Composition and methods for the dyeing of human hair in vivo involving the use of mixtures of aryl and alkyl glycol ethers in aqueous media as carriers and solubilizers for normally waterinsoluble dyes. Applicable classes of dyes are basic, solvent soluble, acid, nitro, premetallized, mordant, anionic and direct.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
47 words
A hair-dyeing composition comprising an aqueous medium containing 1 to 10 grams per liter of a water insoluble dyestuff dissolved in an alcohol selected from the group consisting of methyl alcohol and ethyl alcohol and from 0.5 to 5 percent by weight of ethylene glycol phenyl ether.
Claim 2
Dependent Claim
56 words
A hair-dyeing composition which comprises an aqueous medium containing from 1 to 10 grams per liter of said composition of a water soluble dye, from 0.01 to 5 grams per liter of said composition of a cationic quaternary ammonium salt and from 0.5 to 5 percent by weight of said composition of ethylene glycol phenyl ether.
Claim 3
Dependent Claim
28 words
The hair-dyeing composition of claim 7, wherein said cationic quaternary ammonium salt is selected from the group consisting of a polyethoxylated quaternary ammonium salt and lauryl pyridinium chloride.
Claim 4
Independent Claim
54 words
A method of dyeing human hair in vivo which comprises contacting said human hair at a temperature below 120* F. with an effective amount of a hair-dyeing composition comprising an aqueous medium containing 1 to 10 grams per liter of a dye and 0.5 to 20 percent by weight of ethylene glycol phenyl eTher.
Claim 5
Dependent Claim
31 words
The method of claim 5 wherein said ethylene glycol phenyl ether is present in said dye composition in an amount of from 0.5 to 5 percent by weight of said composition.
Claim 6
Independent Claim
85 words
A method of dyeing human hair in vivo, comprising the steps of contacting said human hair with an effective amount of an aqueous medium containing therein from about 1 to 10 grams per liter of a water-insoluble dye, a sufficient quantity of a water-soluble alcohol selected from the group consisting of methyl alcohol and ethyl alcohol to render said dye soluble in said medium, and 0.5 to 5 percent of ethylene glycol phenyl ether based on the total weight of material contacting said human hair.
Claim 7
Independent Claim
71 words
A method of dyeing human hair in vivo, comprising the steps of contacting said human hair with an effective amount of an aqueous medium containing from 1 to 10 grams per liter of a water-soluble dye, from 0.01 to 5 grams per liter of a quaternary ammonium salt and 0.5 to 20 percent by weight of ethylene glycol phenyl ether based on the total volume of material contacting said human hair.
Claim 8
Dependent Claim
18 words
The method of claim 8 wherein said cationic quaternary ammonium salt is a poly ethoxylated quaternary ammonium salt.
Claim 9
Dependent Claim
17 words
The method of claim 8 wherein said composition is applied to the human hair at ambient temperature.
