DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention is excellent in hair dyeing performance,
The present invention relates to a hair coloring composition that gives a rich texture.

[0002]

2. Description of the Related Art Conventionally, hair dyes containing acid dyes and natural dyes have been widely used in the home, barber and beauty industries because they have less damage to hair than other hair dyes. However, acid hair dyes using acid dyes are so dark that the dyeing liquor is unpleasant when the hair is washed with shampoo after being applied to the hair. The major drawbacks are that the dye solution adheres to clothes, bedding such as pillowcases and sheets, and the hair is wetted by exposing the hair to sweating and rainfall, thereby causing dye transfer to clothing and the like. Furthermore, there is a drawback that a vivid color tone cannot be obtained particularly with black hair. In addition, hair dyes using natural dyes have drawbacks such as insufficient dyeing properties and inferior hair dyeing performance such as discoloration.

[0003] Hair dyes have been proposed which have improved dyeing properties and colorfastness which are disadvantages of hair dyes using such acid dyes and natural dyes. For example, a hair dye composition using a specific acid dye and using glycolic acid and / or pyrrolidone carboxylic acid and / or an alkali metal salt, an alkaline earth metal salt, and an amine salt thereof in combination has also been proposed (Japanese Patent Application Laid-Open No. Hei 6 (1994)). -298630). However, this hair dye composition is not yet satisfactory in terms of dye transfer. Also, as a hair dye composition to make gray hair inconspicuous by using it many times in a usage method like a hair rinse,
A hair dye composition containing an organic solvent, a polyhydric alcohol, an acid dye and an acid has been proposed (JP-A-5-221840).
issue). However, this hair dye composition is also inferior in use convenience, for example, it is necessary to use the hair dye composition many times in order to obtain a sufficient hair dyeing effect. Not satisfactory.

[0004]

SUMMARY OF THE INVENTION The present invention solves the drawbacks of conventional hair dyes using acid dyes and natural dyes, significantly reduces the color of shampoo dyeing solutions during hair dyeing, There is no dye transfer to clothes, bedding, etc., and a vivid color tone can be obtained with a single use, and it has excellent dyeing properties, and it has richness such as suppleness, smoothness, and good finger passage for hair after dyeing. An object of the present invention is to provide an excellent hair dye composition giving a texture.

[0005]

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and have found that glycolic acid and / or a salt thereof is combined with an aliphatic polycarboxylic acid and / or a salt thereof. Thereby, even when using an acid dye or a natural pigment, excellent hair dyeing properties can be obtained, and a rich texture can be imparted to the hair after the hair dyeing treatment, and discoloration to the dye solution can be suppressed, They found that dye transfer to towels, clothing, bedding, etc. could be eliminated, and completed the present invention.

That is, according to the present invention, (A) glycolic acid and / or a salt thereof 0.1 to 2.8% by weight (B) aliphatic polycarboxylic acid and / or a salt thereof 3 to 20% by weight (C) hair containing one or more dyes selected from acid dyes and natural dyes in an amount of 0.01 to 5.0% by weight and having a pH value of 1.5 to 4.5. A hair dye composition is provided. Further, according to the present invention, the (B) fatty acid polycarboxylic acid and / or a salt thereof is succinic acid, malic acid, and / or a salt thereof, wherein the hair dye composition is used. Is provided.
