Abstract

PURPOSE:To obtain a composition for dyeing hair, hardly eliminating color even by washing hair, excellent wet fastness to sweat and water and mildness to human body. CONSTITUTION:This composition for dyeing hair is obtained by combining (A) tannin, preferably hydrolyzable type tannin with (B) an acidic tar coloring matter in the weight ratio of the component B:A=1:0.1 to 1:20, preferably 1:0.2 to 1:15 or (A) tannin with (C) an oxidation dye and (S) an oxidizing agent such as hydrogen peroxide or sodium perborate in the ratio of the component C:A=1:0.1 to 1:20, preferably 1:0.2 to 1:15. When the composition is combined with (D) a cationic polymer, wet fastness can be improved irrespective of kind of dye and especially an amino-modified silicone polymer preferably provides extremely soft touch besides the improving effect on wet fastness.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hair dye composition. More specifically, the present invention relates to a hair dyeing composition suitable for human hair, which has excellent dye fastness to sweat and water even when the hair is washed, and is excellent in wet fastness.

[0002]

2. Description of the Related Art Acidic tar dye-based hair dyes have recently attracted attention because they are effective as semi-permanent hair colors, can be used by people with allergies, and can be easily dyed. Acid tar dyes are usually (95-10
It can be dyed by treating at 0 ° C. for a long time (30 to 60 minutes). However, since the hair of the acidic tar dye-based hair dye is covered with chromosomes, it is impossible to take dyeing conditions at high temperature for a long time. The dyeing temperature is at most room temperature to 50 ° C,
Since the dyeing time is 1 to 20 minutes, the dyed hair has a drawback that when the hair is washed, the dye is severely removed, and the fastness to wetness against sweat and water is poor, and the dye stains clothes. As a conventional technique for improving the drawbacks of the hair wash resistance of these acidic tar dye-based hair dyes, a hair-promoting agent such as resorcin, hydroquinone or gallic acid is contained, and PH1 to PH1.
A hair dye composition characterized by being adjusted to 4.5 (JP-A-60-152408) has been proposed.

[0003]

However, JP-A-60-
Although the hair dye composition of Japanese Patent No. 152408 certainly has slightly improved hair wash resistance as compared with a hair dye containing only an acidic tar dye, it has poor wet fastness to sweat and water,
There is a strong demand for a hair dyeing composition having good fastness.

[0004]

It is preferably 1: 0.2 to 1:15. (A) is 0.
When it is less than 1, the effect of preventing color loss during washing of hair is poor, and the wet fastness to sweat and water is poor. When used in excess of 20, these effects reach equilibrium and no further effects are obtained, which is uneconomical. Rather, the feel of the hair becomes stiff, which is not preferable.

However, when the tannin is combined with the cationic polymer (D), the effect of improving the wet fastness is excellent regardless of the color of the dye. In particular, the amino-modified silicone polymer imparts a very soft tactile sensation in addition to the effect of improving the wet fastness. When the cationic polymer (D) is combined, the weight ratio of (A) :( D) is usually 100:
0.2-100: 200, preferably 100: 0.5-
100: 100, particularly preferably 100: 1 to 100:
