Abstract

The disclosure relates to systems and compositions comprising the systems for use in chemical treatment of keratinous substrates, such as the hair. The systems and compositions comprising the systems comprise at least one active agent and at least one acid. Methods of treating keratinous substrates with the systems and compositions comprising the systems are also disclosed.

Claims

1. A hair treatment composition comprising:

monoethanolamine;

at least one acid chosen from malonic acid, citric acid, or 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 ranging from about 0.1% to about 20% by weight, based on the weight of the hair treatment composition;

wherein the at least one acid chosen from malonic acid, citric acid, or salts thereof is present in an amount ranging from about 0.1% to about 25% by weight, based

on the weight of the hair treatment composition;

wherein the pH of the hair treatment composition ranges from about 2 to about 4; and

wherein the hair treatment composition is not a hair color-altering composition.

2. The hair treatment composition of claim 1, wherein the monoethanolamine is present in an amount ranging from about 1% to about 8% by weight, based on the weight of the hair treatment composition.

3. The hair treatment composition of claim 1, wherein the at least one acid chosen from malonic acid, citric acid, or salts thereof is present in an amount ranging from about 5% to about 12% by weight, based on the weight of the hair treatment composition.

4. The hair treatment composition of claim 1, further comprising at least one colorant compound.

5. The hair treatment composition of claim 1, further comprising at least one additional acid.

6. The hair treatment composition of claim 5, wherein the at least one additional acid is chosen from amino acids, citric acid, hydrochloric acid, phosphoric acid, carbonic acid, acetic acid, glycolic acid, lactic acid, tartaric acid, malic acid, glucuronic acid, acidic plant extracts, and the salt of these acids, and mixtures thereof.

7. A kit comprising:

(a) a first compartment comprising a hair treatment composition comprising;

monoethanolamine;

at least one acid chosen from malonic acid, citric acid, or 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 ranging from about 0.1% to about 20% by weight, based on the weight of the hair treatment composition;

wherein the at least one acid chosen from malonic acid and salts thereof is present in an amount ranging from about 0.1% to about 20% by weight, based on the weight of the hair treatment composition;

wherein the pH of the hair treatment composition ranges from about 2 to about 4; and

wherein the hair treatment composition is not a hair color-altering composition;

(b) a second compartment comprising at least one oxidizing agent; and

(c) optionally, a third compartment comprising at least one coloring component.

8. The kit of claim 7, wherein the monoethanolamine is present in an amount ranging from about 1% to about 8% by weight, based on the weight of the hair treatment composition.

9. The kit of claim 7, wherein the at least one acid chosen from malonic acid, citric acid, or salts thereof is present in an amount ranging from about 5% to about 12% by weight, based on the weight of the hair treatment composition.

10. The kit of claim 7, wherein the hair treatment composition further comprises at least one additional acid.

11. The kit of claim 10, wherein the at least one additional acid is chosen from amino acids, citric acid, hydrochloric acid, phosphoric acid, carbonic acid, acetic acid, glycolic acid, lactic acid, tartaric acid, malic acid, glucuronic acid, acidic plant extracts, and the salt of these acids, and mixtures thereof.
