Abstract

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

First claim

What is claimed is:

1. A hair conditioning composition comprising:
at least one monoamine chosen from 3-isopropoxypropylamine, 3-methoxypropylamine, tris(hydroxymethyl)aminomethane, 3-ethoxypropylamine, 3-(2-ethylhexyloxy)-propylamine, 2-(2-aminoethoxy)ethanol, 3-butoxypropylamine, monoethanolamine, or combinations thereof,
at least one carboxylic acid chosen from maleic acid, citric acid, salts thereof, or combinations thereof;
at least one conditioning agent; and
at least one solvent,
wherein the composition comprises a total amount of monoamines up to about 10%;
wherein the composition comprises a total amount of carboxylic acids chosen from maleic acid, citric acid, and salts thereof up to about 10%; and
wherein the pH of the composition ranges from about 1 to about 7.

2. The hair conditioning composition of claim 1 , wherein the at least one carboxylic acid is chosen from citric acid, salts thereof, or combinations thereof.

3. The hair conditioning composition of claim 1 , wherein the at least one carboxylic acid is chosen from maleic acid, salts thereof, or combinations thereof.

4. The hair conditioning composition of claim 1 , wherein the composition comprises a total amount of carboxylic acids chosen from maleic acid, citric acid, and salts thereof in an amount ranging from about 0.50% to about 5% by weight, based on the weight of the hair treatment composition.

5. The hair conditioning composition of claim 1 , wherein the composition comprises a total amount of monoamines in an amount ranging from about 0.50% to about 5% by weight, based on the weight of the hair treatment composition.

6. The hair conditioning composition of claim 1 , wherein the solvent is chosen from water, cosmetically acceptable organic solvents, or combinations thereof.

7. The hair conditioning composition of claim 1 , further comprising at least one additive chosen from surfactants and/or thickening agents.

8. The hair conditioning composition of claim 1 , comprising at least one conditioning agent chosen from cationic conditioning agents, amphoteric conditioning agents, or combinations thereof.

9. The hair conditioning composition of claim 1 having a pH ranging from about 2 to about 5.

10. A method of treating the hair, said method comprising:
(a) applying to the hair a conditioning composition comprising:
at least one monoamine chosen from 3-isopropoxypropylamine, 3-methoxypropylamine, tris(hydroxymethyl)aminomethane, 3-ethoxypropylamine, 3-(2-ethylhexyloxy)-propylamine, 2-(2-aminoethoxy)ethanol, 3-butoxypropylamine, monoethanolamine, or combinations thereof;
at least one carboxylic acid chosen from maleic acid, citric acid, salts thereof, or combinations thereof;
at least one conditioning agent; and
at least one solvent,
wherein the composition comprises a total amount of monoamines up to about 10%;
wherein the composition comprises a total amount of carboxylic acids chosen from maleic acid, citric acid, and salts thereof up to about 10%; and
wherein the pH of the composition ranges from about 1 to about 7; and

(b) rinsing the hair.

11. The method of claim 10 , wherein the at least one carboxylic acid is chosen from citric acid, salts thereof, or combinations thereof.

12. The method of claim 10 , wherein the at least one carboxylic acid is chosen from maleic acid, salts thereof, or combinations thereof.

13. The method of claim 10 , wherein the composition comprises a total amount of carboxylic acids chosen from maleic acid, citric acid, and salts thereof in an amount ranging from about 0.50% to about 5% by weight, based on the weight of the hair treatment composition.

14. The method of claim 10 , wherein the composition comprises a total amount of monoamines in an amount ranging from about 0.50% to about 5% by weight, based on the weight of the hair treatment composition.

15. The method of claim 10 , wherein the solvent is chosen from water, cosmetically acceptable organic solvents, and combinations thereof.

16. The method of claim 10 , wherein the conditioning composition further comprises at least one additive chosen from surfactants and/or thickening agents.

17. The method of claim 10 , wherein the conditioning composition comprises at least one conditioning agent chosen from cationic conditioning agents, amphoteric conditioning agents, or combinations thereof.

18. The method of claim 10 , wherein the conditioning composition has a pH ranging from about 2 to about 5.
