Abstract

Hair dye compositions comprise (A) ammonia or an ammonium salt, (B) a carbonate (other than an ammonium salt), (C) a transition metal salt, and (D) a chelating agent, and have a pH of from 8.5 to 12. They do not give off an intensely irritating odor and have low irritating property, can change hair into a lighter tone in a short time or can dye hair well in a color ranging from a light color to a deep color, and moreover, assure good retention of the thus-obtained tone or color.

Claims

1. A method of dyeing the hair, comprising:

mixing a first pack formulation and a second pack formulation, said first pack formulation comprising the following ingredients (A) to (D);

2. The method of dyeing hair of claim 1, wherein the second pack formulation contains about 6 wt% hydrogen peroxide.

3. The method of dyeing hair of claim 1, wherein the hair is dyed at a temperature ranging from about 15 to 40°

C. for about 1 to 50 minutes.

4. The method of dyeing hair of claim 3, wherein the hair is dyed for about 10 to 30 minutes.

5. The method of dyeing hair of claim 1, wherein the applied formulation is removed from the hair by washing the hair.

6. The method of dyeing hair of claim 1, wherein the content of said ingredient (D) in the first pack formulation is 0.01 to 10 wt% based on said composition.

7. The method of dyeing hair of claim 1, wherein said water soluble salt of iron is ferrous sulfate or ferrous chloride.

8. The method of dyeing hair of claim 1, wherein the chelating agent (D) is ethylenediaminetetraacetic acid, hydroyethylethylenediaminetriacetic acid, diethylenetriaminepentaacetic acid, nitrilotriacetic acid, triethylenetetraminehexaacetic acid, a phosphonic acid, tripolyphosphoric acid, ascorbic acid, citric acid, maleic acid or salts thereof.

9. The method of dyeing hair of claim 1, wherein said carbonate (B) of the first pack formulation is sodium carbonate, sodium hydrogencarbonate, potassium carbonate, potassium hydrogencarbonate, guanidine carbonate, guanidine hydrogencarbonate, lithium carbonate, calcium carbonate, magnesium carbonate or barium carbonate.

10. The method of dyeing hair of claim 1, wherein said pH ranges from 9to 11.5.

11. The method of dyeing hair of claim 1, wherein the amount of said carbonate in the composition ranges from 0.01 to 0.5 mol/kg.

12. The method of dyeing hair of claim 1, wherein said molar ratio of (A) to (B) ranges from 0.2 to 3.
