Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dyeing composition for hair dyeing, and more particularly, to a hair dyeing composition which has little discoloration, has no migratory property, and has a vivid dyeing color. In addition, the present invention relates to a hair dye composition which is excellent in hair dyeability, suppleness and combability of hair after hair dyeing.

[0002]

2. Description of the Related Art Hair dyes containing acid dyes and natural dyes are widely used at home and in beauty salons because they have less damage to hair than other hair dyes. However, when the acid dye hair dye is applied to the hair and then washed away with shampoo, the washing liquid has an unpleasantly unpleasant dye color, and the dye solution adheres to the towel or pillow cover after shampooing, or causes perspiration or perspiration. It has the disadvantage that when hair is wet due to rainfall, it is transferred to clothing and the like. In addition, there is a disadvantage that a vivid color tone cannot be obtained particularly with black hair.

[0003] In order to improve such disadvantages as dyeing property and colorfastness, specific acid dyes are used, and glycolic acid and / or pyrrolidone carboxylic acid and / or their alkali metal salts and alkaline earths are used. A hair dye composition using a combination of a metal salt and an amine salt has also been proposed (JP-A-6-2).
No. 98630), which is not yet satisfactory in terms of transferability.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the drawbacks of conventional hair dyes using acid dyes and natural dyes, significantly reduces the color of the shampoo washing solution during hair dyeing, It does not transfer to clothes and skin, such as pillowcases and pillows, provides vivid colors, and has excellent dyeing properties, and has excellent flexibility, smoothness, and combability after dyeing hair. It is intended to provide a hair dye composition.

[0005]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventor has found that acid dyes and natural dyes are prevented from discoloring into a washing solution, and are not migrating to clothes and the like. For this purpose, it has been found that the problem can be solved by blending tartaric acid and / or a salt thereof in the hair dye, and it has also been found that discoloration to the washing solution and to obtain a vivid color tone complete the present invention. Reached.

That is, according to the present invention, (A) an acid dye or a natural pigment, (B) an organic solvent, (C) tartaric acid and / or a salt thereof containing 0.1 to 20% by weight, and a pH of 2.0 to 2.0. 5.0 is provided.

Sodium hydroxide. Furthermore, it is also preferable to use a basic amino acid such as arginine.

In addition, these acids and alkalis can coexist and be used as, for example, the sodium, potassium, ammonium and triethanolamine salts of the above-mentioned acids. When the pH of the hair dye is in the range of 2.0 to 5.0 depending on the amount of the tartaric acid component, it is not necessary to further add another organic acid or the like for adjusting the pH.

The hair dye of the present invention includes various surfactants, cationic polymers, oily components, thickeners such as hydroxyethylcellulose and xanthan gum, silicone derivatives, fragrances, and the like, as long as the effects of the present invention are not impaired. Preservative,
