Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye composition for hair dyeing, and more specifically, when dyeing hair, there is little discoloration, no transferability, and a bright hair dyeing color. Further, the present invention relates to a hair dye composition excellent in hair dyeing properties, suppleness and combability of hair after dyeing.

[0002]

2. Description of the Related Art Hair dyes containing acid dyes and natural dyes have less hair damage than other hair dyes and are therefore widely used at home and in beauty salons. However, when the acid dye hair dye is applied to hair and then washed off with shampoo, the wash liquid has a dark pigment color that is unpleasant to wash, and after the shampoo, the dye liquid adheres to the towel or pillow cover, and sweating or sweating occurs. It has a drawback that when hair gets wet due to rainfall, it is transferred to clothing or the like. In particular, black hair has a drawback that it cannot obtain a vivid color tone.

In order to improve the dyeing properties, color fastness and the like, which are such drawbacks, a specific acid dye is used and glycolic acid and / or pyrrolidonecarboxylic acid and / or their alkali metal salts and alkaline earth are used. A hair dye composition in which a metal salt and an amine salt are used in combination is also proposed (JP-A-6-2).
No. 98630), it is still unsatisfactory in terms of transferability.

Further, as a hair dye composition which makes white hair inconspicuous by using it many times in a method such as hair rinse, it contains an acid dye and an organic solvent and has a pH of 2.0.
.About.4.5, a salt of an organic acid or the like is added, and a buffering capacity of 0.
Although a hair dye composition having an amount of 01 to 0.2 gram equivalent / l has been proposed (Japanese Patent Laid-Open No. 5-78228), it is necessary to use the hair dye a large number of times. Those containing sodium citrate and sodium lactate are not yet satisfactory in terms of dye transfer property and texture.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the drawbacks of conventional hair dyes using acidic dyes and natural dyes, and significantly reduces the color of shampoo washing liquid when dyeing hair, and towels. Hair dye that does not transfer to clothing such as clothes and pillow covers, skin, etc., and can obtain a vivid color tone, has excellent dyeability, and has excellent suppleness and combability of the hair after dyeing. It is intended to provide a composition.

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventor has suppressed the discoloration of acid dyes and natural pigments in washing liquids and eliminated the transferability to clothes and the like. In order to achieve this, it has been found that the solution can be solved by incorporating a specific liquid of glycolic acid, namely ammonium glycolate, into the hair dye, and also the fading of such a washing liquid and the suppression of dye transferability. In addition, in order to obtain a vivid color tone even with black hair, it has been found that it can be solved by further adding hydrogen peroxide to the hair dye and dyeing hair while bleaching, and completed the present invention. .

That is, according to the present invention, (A) 0.01 to 2% by weight of an acid dye or a natural pigment (B) 0.5 to 50% by weight of an organic solvent (C) 0.1 to 20% of ammonium glycolate There is provided a hair dye composition, characterized in that it contains 10% by weight and has a pH of 2.0 to 4.5. Further, according to the present invention, (A) 0.01 to 2% by weight of an acid dye or a natural pigment (B) 0.5 to 50% by weight of an organic solvent (C) 0.1 to 20% by weight of ammonium glycolate ( D) A hair dye composition comprising 0.1 to 5% by weight of hydrogen peroxide and having a pH of 2.0 to 4.5 is provided.
