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; monovalent or divalent metal salts of organic acids; and antioxidants, wherein the pre-color treatments are applied to hair prior to artificially coloring hair.
Claims30
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:
- at least 0.5 wt. % of one or more divalent metal salts of an inorganic acid;
- at least 0.5 wt. % of one or more monovalent or divalent metal salts of an organic acid;
- and
- at least 0.5 wt. % of one or more antioxidants;
- all weights being based on the total weight of the pre-color treatment composition;
- 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.
A multi-compartment kit for altering the color of hair, the kit comprising:
- (i) a pre-color treatment component comprising one or more divalent metal salts of an inorganic acid;
- one or more monovalent or divalent metal salts of an organic acid;
- and one or more antioxidants;
- (ii) a hair coloring composition comprising one or more colorants chosen from oxidative dye precursors, direct dyes, pigments, and mixtures thereof;
- and
- (iii) 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.
A pre-color treatment composition comprising:
- about 0.5 wt. % to about 20 wt. % of one or more divalent metal salts of an inorganic acid 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;
- and
- about 0.5 wt. % to about 20 wt. % of one or more monovalent or divalent metal salts of an organic acid chosen from zinc lactate, zinc gluconate, zinc phenolsulfonate, zinc salicylate, zinc pyrrolidone carboxylic acid (Zinc PCA), zinc citrate, zinc ascorbate, 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;
- and
- about 0.5 wt. % to about 30 wt. % of one or more antioxidants are chosen from ascorbic acid and its derivatives, sodium sulfite, sodium metabisulfite, sodium hydrosulfite, tocopherols, alpha-tocopherol, tocopheryl acetate, EDTA, panthenol, selenium sulfide, zinc formosulfoxylate, erythorbic acid, isoascorbic acid, thioglycolate salt, magnesium ascorbyl phosphate, ascorbyl glucoside, cysteine, thiourea, thiolactic acid, glyceryl monothioglycolate, thioglycerol, 2,5-dihydroxybenzoic acid, Butylated hydroxytoluene (BHT), Butylated hydroxyanisole (BHA), N,N′-bis(3,4,5-trimethoxybenzyl)ethylenediamine and its salts, and mixtures thereof;
- all weights being based on the total weight of the composition.
