Abstract

The present disclosure relates to compositions and methods for improving the quality and durability of color in artificially colored hair. The methods employ pre-color treatments containing divalent metal salts of inorganic acids and monovalent or divalent metal salts of organic acids (treatments to the hair prior to artificial coloring of hair) and optionally, post-color treatments containing silane compounds (treatments to the hair after artificial coloring of hair).

First claim

The invention claimed is:

1. A method for artificially coloring hair and inhibiting the coloring from fading, the method comprising:
(a) treating hair with a pre-color treatment composition comprising about 0.1 wt. % to about 50 wt. % of one or more divalent metal salts of an inorganic acid and about 0.1 wt. % to about 50 wt. % of one or more monovalent or divalent metal salts of an organic acid; and
(b) treating the hair with a hair coloring composition comprising one or more colorants chosen from oxidative dye precursors, direct dyes, pigments, and mixtures thereof,
wherein the weight ratio of the one or more divalent metal salts of an inorganic acid to the one or more monovalent or divalent metal salts of an organic acid is from about 10:1 to about 1:10, and
all weights being based on the total weight of the pre-color treatment composition.

2. The method of claim 1 , wherein the one or more divalent metal salts of an inorganic acid are chosen from metal halides, metal hydroxides, metal sulfates, metal oxides, and mixtures thereof.

3. The method of claim 1 , wherein the one or more divalent metal salts of an inorganic acid are chosen from salts of calcium, zinc, iron, nickel, copper, silver, magnesium, strontium, barium, manganese, cobalt, and mixtures thereof.

4. The method of claim 1 , 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 and wherein the one or more monovalent metal salts of an organic acid are chosen from salts of lithium, sodium, potassium, copper, silver, and mixtures thereof.

5. The method 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.

6. The method of claim 1 , wherein the one or more divalent metal salts of an inorganic acid includes a calcium salt.

7. The method of claim 1 , wherein the calcium salt is calcium chloride.

8. The method of claim 1 , wherein 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 including ascorbic acid, formic acid, acetic acid, glycolic acid, gluconic acid, lactic acid, mandelic acid, oxalic acid, maleic acid, malonic acid, glyoxylic acid, succinic acid, adipic acid, fumaric acid, sebacic acid, including citric acid, tartaric acid, malic acid, 2-hydroxy malonic acid, 2-hydroxyl n-butyl 1,2,4-tricarboxylic acid, glutaric acid, glucaric acid, 2-hydroxy n-butyl 1,3,4-tricarboxylic acid, pyrrolidone carboxylic acid, phenolsulfonic acid, and salicylic acid.

9. The method 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.

10. The method 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.

11. The method of claim 1 , wherein the pre-color treatment 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 method of claim 1 , wherein the amount of the one or more divalent metal salts of an inorganic acid is greater than the amount of the one or more monovalent or divalent metal salts of an organic acid.

13. The method of claim 1 , wherein the amount of the one or more divalent metal salts of an inorganic acid is less than the amount of the one or more monovalent or divalent metal salts of an organic acid.

14. The method of claim 1 , wherein the hair coloring composition further comprises one or more oxidizing agents or is 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.

15. The method of claim 1 , wherein upon treating the hair with the pre-color treatment composition in (a), the pre-color treatment composition is allowed to remain on the hair for at least 30 seconds before treating the hair with the hair coloring composition in (b).

16. The method of claim 1 , further comprising a step of treating the hair with a post-color treatment composition after treating the hair with the hair coloring composition in (b).

17. The method of claim 16 , wherein the post-color treatment composition comprises from about 1 wt. % to about 30 wt. %, based on the total weight of the composition, of one or more silane compounds corresponding to formula (Ia):
