Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acidic hair dye composition for hair. 2. Description of the Related Art Conventionally, acidic hair dyes for hair have been used as acid dyes and hair dye accelerators (eg, benzyl alcohol, n
-Butanol, etc., a dissolution aid (eg, N-methylpyrrolidone, ethylene carbonate, etc.) and an acid or a salt thereof (eg, citric acid, sodium citrate).
It is adjusted to 1.5 to 4.5 and contains a thickener (eg, hydroxyethyl cellulose, xanthan gum) and the like. However, disadvantages of existing acidic hair dyes for hair include the following. [0004] 1. 1. poorer dyeing than oxidative hair dye; 2. It is easy to discolor and stains clothes and towels; The hair becomes squeaky and dry. SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of 1, 2, and 3, and provides an acidic hair dye composition for hair having excellent dyeing properties, fastness and texture. The purpose is to provide. According to the present invention, there is provided a triphenylmethane dye comprising 3 to 15% by weight of glycolic acid and / or pyrrolidonecarboxylic acid and / or a salt thereof as an acid.
0.1-5. One or more dyes selected from the group consisting of azo dyes, quinoline dyes, xanthene dyes, indigo dyes, anthraquinone dyes and nitro dyes;
0% by weight, and the pH value was adjusted to 1.5 to 4.5. That is, the present invention relates to glycolic acid and / or pyrrolidonecarboxylic acid or a salt thereof in an amount of 3 to 15% by weight, triphenylmethane dye, azo dye, quinoline dye, xanthene dye, indigo dye, anthraquinone dye and nitro dye. 0.1 to 5.0% by weight of one or more dyes selected from the group consisting of
The present invention provides an acidic hair dye composition for hair whose value is adjusted to 1.5 to 4.5. [0008] The composition of the present invention has a pH value of 1.5 to 4.
In the range of 5, glycolic acid, pyrrolidone carboxylic acid or a salt thereof is blended. Glycolic acid, pyrrolidone carboxylic acid or salts thereof may be used alone or in combination of two or more. These carboxylic acids or salts thereof are added in an amount of 3 to 15% by weight, preferably 5 to 10% by weight. When the pH value is in the range of 1.5 to 4.5 and the blending ratio of glycolic acid and / or pyrrolidone carboxylic acid or a salt thereof is smaller than the above range, the dyeing property is reduced. And the smoothness is lost. The pyrrolidonecarboxylic acid may be used in an optically active form (d-form or l-form), and in a racemic form (dl-form).
Body). In the present invention, the salts of glycolic acid and pyrrolidonecarboxylic acid include sodium salts thereof,
Examples thereof include alkali metal salts such as potassium salts, alkaline earth metal salts such as calcium salts and magnesium salts, and amine salts such as monoethanolamine, diethanolamine, and triethanolamine. The dyes to be incorporated into the acidic hair dye composition for hair of the present invention include the following. * Triphenylmethane dye: Blue No. 1, etc. * Azo dye: Orange No. 205, etc. * Quinoline dye: Yellow No. 203, etc. * Xanthene dye: Red No. 106, etc. * Indigo dye: Blue No. 2, etc. * Anthraquinone dye: Purple No. 401, etc. * Nitro dye: Yellow 403 No. (1), etc. The acidic hair dye composition for hair of the present invention contains one or more of the above dyes in an amount of 0.1 to 5.0% by weight, preferably 0.5 to 3.0% by weight. The acidic hair dye composition for hair of the present invention may further contain a hair dye accelerating agent (eg, benzyl alcohol, n-butanol, etc.), a thickener (eg, hydroxyethyl cellulose, xanthan gum, etc.), a surfactant or a surfactant. Additives such as solubilizers (eg, polyoxyethylene castor oil), gelling inhibitors (eg, glycerin) can be added. Those skilled in the art can easily determine the amount of the additive. The acidic hair dye composition for hair of the present invention can be prepared by adding glycolic acid and / or pyrrolidone carboxylic acid or a salt thereof as an acid or a salt thereof to obtain a pH.
Is adjusted to 1.5-4.5. When the pH value is lower than the above range, flexibility and smoothness are lost, and when the pH value is higher, the dyeing property is reduced. EFFECT OF THE INVENTION The acidic hair dye of the present invention has good dyeing properties and texture, and has less discoloration. Furthermore, it gives the hair after dyeing suppleness and combability. Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these Examples. Example 1 and Comparative Example 1 The effects of glycolic acid and pyrrolidone carboxylic acid used in the present invention were confirmed as follows. The hair dye base used in this experiment is described below. In 100 g of this product: Daidoiro No. 205 0.5 g Benzyl alcohol 8.0 g N-methylpyrrolidone 12.0 g Acid A suitable amount adjusted to 100 g Purified water As the acid in the hair dye base, glycolic acid and pyrrolidone carboxylic acid are used. Table 1 shows the results of dyeing bleached white hair using dye solutions to which acids were added at various concentrations. The evaluation of the dyeing property was carried out by uniformly applying the above-mentioned dyeing solution to the whole white hair, leaving the hair at 25 ° C. for 30 minutes, washing with warm water, shampooing and washing with water, and drying the hair with a dryer. This was performed using Evaluation of discoloration was carried out after the same operation as the dyeing property, but before drying, by sandwiching between filter papers and observing stains on the filter papers. The pH value of the undiluted solution was measured at 20 ° C using a glass electrode p.
It was measured with an H meter. As Comparative Example 1, a hair dye base was similarly prepared using citric acid, levulinic acid, and phosphoric acid as the acid component in the hair dye base, and the evaluation results are shown in Table 2. In Tables 1 and 2: Evaluation of Dyeing Ability: A deep orange color is exhibited. ：: An orange color is exhibited. Δ: A slightly pale orange color is exhibited. ×: Presents a pale orange color. Color fall ◎: Color is hardly attached to the filter paper. ：: The filter paper becomes thin orange. Δ: The filter paper turns orange. ×: The filter paper turns deep orange. Texture: Good flexibility and combability. Δ: Slightly pliable, poor combing. ×: There is no flexibility, and comb passing is poor. [Table 1] [Table 2] The discoloration of citric acid and levulinic acid was remarkable, and the dyeing properties were poor. Phosphoric acid showed good results in dyeing properties and discoloration, but had a poor texture. It is desirable to add a thickener, an anti-gelling agent, and a fragrance to the acidic hair dye for hair of the present invention in consideration of the usability during treatment.
