Abstract

The present disclosure relates to compositions and methods for improving the quality and durability of color in artificially colored hair. The compositions are hair coloring compositions that employ divalent metal salts of inorganic acids, monovalent or divalent metal salts of organic acids and colorants. Methods are described wherein hair is contacted with the compositions of the present disclosure, resulting in improved artificial color deposition, as well as improved quality and durability of the color in artificially colored hair.

First claim

The invention claimed is:

1. A hair coloring composition comprising, in a cosmetically acceptable solvent:
(a) above 0 wt. % to about 50 wt. % of one or more divalent metal salts of an inorganic acid chosen from salts of calcium, zinc, iron, nickel, copper, silver, magnesium, strontium, barium, manganese, cobalt, and mixtures thereof;
(b) above 0 wt. % to about 50 wt. % of one or more monovalent or divalent metal salts of an organic acid, wherein
the one or more divalent metal salts of an organic acid are chosen from salts of calcium, zinc, iron, nickel, copper, silver, magnesium, strontium, barium, manganese, cobalt, and mixtures thereof,
the one or more monovalent metal salts of an organic acid are chosen from salts of lithium, sodium, potassium, copper, silver, and mixtures thereof, and
the organic acid of the one or more monovalent or divalent metal salts of an organic acid is chosen from C1 to C9 monocarboxylic or di-carboxylic acids, polycarboxylic acids, hydroxy-carboxylic acids, and fatty acids having at least 10 carbon atoms; and

(c) one or more colorants chosen from oxidative dye precursors, direct dyes, pigments, and mixtures thereof.

2. The hair coloring composition of claim 1 , wherein the one or more divalent metal salts of an inorganic acid are chosen from calcium chloride, calcium sulfate, calcium nitrate, calcium carbonate and hydrogen carbonate, calcium phosphate, zinc chloride, zinc sulfate, zinc nitrate, zinc carbonate and hydrogen carbonate, zinc phosphate, magnesium chloride, magnesium sulfate, magnesium nitrate, magnesium carbonate and hydrogen carbonate, magnesium phosphate, strontium chloride, strontium nitrate, barium chloride, barium nitrate, and mixtures thereof.

3. The hair coloring composition of claim 1 , wherein the one or more divalent metal salts of an inorganic acid includes a calcium salt.

4. The hair coloring composition of claim 3 , wherein the calcium salt is calcium chloride.

5. The hair coloring composition of claim 1 , wherein the one or more divalent metal salts of an inorganic acid are present in an amount of from about 0.75 wt. % to about 8 wt. %, based on the total weight of the hair coloring composition.

6. The hair coloring composition of claim 1 , wherein the one or more divalent metal salts of an organic acid are chosen from zinc lactate, zinc gluconate, zinc phenolsulfonate, zinc salicylate, zinc pyrrolidone carboxylic acid (Zinc PCA), zinc citrate, zinc ascorbate, their salt derivatives thereof, and mixtures thereof.

7. The hair coloring composition of claim 1 , wherein the one or more divalent metal salts of an organic acid includes a zinc salt.

8. The hair coloring composition of claim 7 , wherein the zinc salt is zinc gluconate.

9. The hair coloring composition of claim 1 , wherein the one or more monovalent metal salts of an organic acid are chosen from sodium ascorbate, sodium formate, sodium gluconate, sodium glutamate, sodium glycolate, sodium glyoxylate, sodium citrate, sodium acetate, sodium lactate, sodium malate, sodium salicylate, potassium acetate, potassium citrate, potassium gluconate, potassium lactate, lithium myristate, lithium stearate, lithium gluconate, silver citrate, silver lactate, silver salicylate, their derivatives thereof, and mixtures thereof.

10. The hair coloring composition of claim 1 , wherein the one or more monovalent or divalent metal salts of an organic acid are present in an amount of from about 0.75 wt. % to about 8 wt. %, based on the total weight of the hair coloring composition.

11. The hair coloring composition of claim 1 , wherein the composition comprises one or more divalent metal salts of an inorganic acid chosen from calcium chloride and one or more divalent metal salts of an organic acid chosen from zinc gluconate.

12. The hair coloring composition of claim 1 , wherein the hair coloring composition is formed from the combination of:

the one or more divalent metal salts of an inorganic acid; and
the one or more monovalent or divalent metal salts of an organic acid;
wherein the one or more divalent metal salts of an inorganic acid and the one or more monovalent or divalent metal salts of an organic acid are provided as separate components or together as one metal salt component.

13. The hair coloring composition of claim 12 , wherein the weight ratio of the total amount of metal salts to the amount of the color cream composition is from about 5:1 to about 1:5.

14. The hair coloring composition of claim 1 , further comprising one or more oxidizing agents or capable of being mixed with an oxidizing composition comprising: (i) one or more oxidizing agents; and (ii) a cosmetically acceptable solvent chosen from water and a water/organic solvent mixture; wherein the one or more oxidizing agents are chosen from peroxides, persulfates, perborates, percarbonates, alkali metal bromates, ferricyanides, laccases, peroxidases, redox enzymes, their salts thereof, and mixtures thereof.
