Abstract
The present disclosure relates to color-altering compositions. The compositions comprise a hair color-altering agent and at least one carboxylic acid. Certain compositions further comprise at least one amino acid or amino sulfonic acid, and/or a salt thereof selected from the group consisting of taurine, aspartic acid, cysteine, lysine, methionine, tyrosine, phenylalanine, carnitine, a salt thereof, and a mixture thereof. Also provided are kits and methods of using said color-altering compositions.
Claims20
A hair color-altering composition comprising:
- about 0.01 wt. % to about 10 wt. % of taurine;
- about 1 wt. % to about 10 wt. % of citric acid;
- at least one oxidative dye selected from oxidation bases, couplers, or combinations thereof;
- about 7 wt. % to about 10 wt. % of monoethanolamine;
- about 5 wt. % to about 20 wt. % of ammonium hydroxide;
- about 1 wt. % to about 5 wt. % of oleic acid;
- and
- water.
A hair color-altering composition comprising:
- about 0.05 wt. % to about 1 wt. % of taurine;
- about 1 wt. % to about 2 wt. % of citric acid;
- at least one oxidative dye selected from oxidation bases, couplers, or combinations thereof;
- at least two alkalizing agents chosen from monoethanolamine and ammonium hydroxide, wherein the total amount of alkalizing agents ranges from 10 wt. % to about 20 wt. %;
- about 1 wt. % to about 5 wt. % of oleic acid;
- and
- water,
