Abstract

The disclosure relates to compositions for treating keratinous substrates, such as the hair, comprising monoethanolamine and at least one carboxylic acid, as well as systems and methods for treating keratinous substrates with the compositions.

Claims

1. A method for altering the color of the hair, the method comprising:

a) mixing a hair treatment composition and a color-altering composition;

wherein the hair treatment composition comprises;

monoethanolamine;

at least one carboxylic acid chosen from maleic acid and salts thereof;

at least one solvent chosen from water, cosmetically acceptable organic solvents, and combinations thereof,

wherein the pH of the hair treatment composition is of about 3;

wherein the monoethanolamine is present in an amount of about 5.4% by weight, based on the weight of the hair treatment composition;

wherein the at least one carboxylic acid chosen from maleic acid and salts thereof is present in an amount of about 10.7% by weight, based on the weight of the hair treatment composition; and

wherein the color-altering composition comprises at least one bleaching agent and optionally at least one colorant compound;

b) applying the mixture to the hair; and

c) applying to the hair a conditioning composition comprising;

monoethanolamine;

at least one carboxylic acid chosen from maleic acid and salts thereof; and

at least one solvent chosen from water, cosmetically acceptable organic solvents, and combinations thereof,

wherein the monoethanolamine is present in an amount of about 1% by weight, based on the weight of the conditioning composition;

wherein the at least one carboxylic acid chosen from maleic acid and salts thereof is present in an amount of about 1.9% by weight, based on the weight of the conditioning composition.

2. The method according to claim 1, wherein the hair treatment composition further comprises at least one colorant compound.

3. The method according to claim 1, wherein said hair treatment composition further comprises at least one additional carboxylic acid.

4. The method according to claim 3, wherein the at least one additional carboxylic acid is chosen from:

oxalic acid, malonic acid, malic acid, glutaric acid, citraconic acid, citric acid, glycolic acid, succinic acid, adipic acid, tartaric acid, fumaric acid, sebacic acid, benzoic acid, and glyoxylic acid monohydrate;

salts thereof; and

combinations thereof.

5. The method according to claim 1, wherein the color-altering composition comprises at least one bleaching agent chosen from peroxides, persulfates, perborates, percarbonates, peracids, bromates, their salts, and mixtures thereof.

6. The method according to claim 1, wherein the mixing occurs less than one hour prior to application of the mixture to the hair.

7. The method of claim 1, wherein the hair is rinsed prior to the application of the conditioning composition.

8. The method of claim 1, wherein the conditioner composition further comprises at least one of quaternium-91, acrylates copolymer, cetrimonium chloride, phenoxyethanol, sorbitan oleate, polyquarternium-37, glycerin, propylene glycol, cetrimonium methosulfate, benzoic acid, cetearyl alcohol, stearamidopropyl dimethylamine, mineral oil, behentrimonium methosulfate, and/or hydroxyethylcellulose.
