Abstract

PURPOSE:To obtain an acidic hair dye composition for the hair of the head, good in dyeability and hand with hardly any crocking and capable of providing pliability and excellence in combing properties to the hair after dyeing thereof. CONSTITUTION:This acidic hair dye composition for the hair of the head is obtained by blending 3-15wt.% glycolic acid and/or pyrrolidonecarboxylic acid and/or salts thereof with 0.1-5.0wt.% one or two or more dyes selected from the group consisting of triphenylmethane, azo, quinoline, xanthene, indigo, anthraquinone and nitro-based dyes and regulating the pH value to 1.5-4.5.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an acidic hair dye composition for hair.

[0002]

2. Description of the Related Art Conventionally, acidic hair dyes for hair have been treated with acid dyes and hair dye accelerators (eg, benzyl alcohol, n.
PH with butanol) and solubilizers (eg N-methylpyrrolidone, ethylene carbonate etc.) and acids or their salts (eg citric acid, sodium citrate)
It is adjusted to 1.5 to 4.5, and a thickener (eg, hydroxyethyl cellulose, xanthan gum) or the like is added.

However, the drawbacks of the existing acidic hair dyes for hair include the following.

1. Dyeing is worse than oxidative hair dyes; 1. 3. It is easy to discolor and stain clothes and towels; The hair feels tight or dry.

[0005]

DISCLOSURE 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, which is excellent in dyeing property, fastness, and texture. The purpose is to

[0006]

According to the present invention, glycolic acid and / or pyrrolidonecarboxylic acid and / or a salt thereof is used as an acid in an amount of 3 to 15% by weight, a triphenylmethane dye,
0.1 to 5. One or more dyes selected from the group consisting of azo dyes, quinoline dyes, xanthene dyes, indigo dyes, anthraquinone dyes and nitro dyes.
It is characterized in that 0% by weight is blended and the pH value is adjusted to 1.5 to 4.5.

That is, the present invention comprises 3 to 15% by weight of glycolic acid and / or pyrrolidonecarboxylic acid or salts thereof, 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, the value of which is adjusted to 1.5 to 4.5.

The composition of the present invention has a pH value of 1.5-4.
In the range of 5, glycolic acid, pyrrolidonecarboxylic acid or salts thereof are blended. Glycolic acid, pyrrolidonecarboxylic acid or salts thereof may be used alone or in combination of two or more kinds. These carboxylic acids or salts thereof are added in the range of 3 to 15% by weight, preferably 5 to 10% by weight. When the blending ratio of glycolic acid and / or pyrrolidonecarboxylic acid or a salt thereof is less than the above range within a pH value range of 1.5 to 4.5, the dyeing property is reduced, and when it is greater than the above range, the suppleness is high. And the smoothness is lost.

The pyrrolidonecarboxylic acid may be used in an optically active form (d-form or l-form), and a racemic form (dl-form).
Body) may be used.

In the present invention, the salts of glycolic acid and pyrrolidonecarboxylic acid are sodium salts of these,
Examples thereof include alkali metal salts such as potassium salt, alkaline earth metal salts such as calcium salt and magnesium salt, amine salts such as monoethanolamine, diethanolamine and triethanolamine.

The dyes to be added to the acidic hair dye composition for hair of the present invention include the following.

* Triphenylmethane dye: Blue No. 1 etc. * Azo dye: Daidai 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 No. 403 (1), etc.

The acidic hair dye composition for hair of the present invention contains 0.1 to 5.0% by weight, preferably 0.5 to 3.0% by weight, of one or more of the above dyes.

The acidic hair dye composition for hair of the present invention further comprises a hair dye promoter (eg, benzyl alcohol, n-butanol, etc.), a thickener (eg, hydroxyethyl cellulose, xanthan gum, etc.), a surfactant or an optional agent. Additives such as a solubilizer (eg, polyoxyethylene castor oil) and an antigelling agent (eg, glycerin) can be added. The amount of the additive added can be easily determined by those skilled in the art.

The acidic hair dye composition for hair of the present invention can be adjusted to pH by adding glycolic acid and / or pyrrolidonecarboxylic acid or a salt thereof as an acid or a salt thereof.
Is adjusted to 1.5 to 4.5.

When the pH value is lower than the above range, the flexibility and smoothness are lost, and when the pH value is higher, the dyeing property is deteriorated.

[0017]

EFFECTS OF THE INVENTION The acidic hair dye of the present invention has good dyeing properties and texture and less color loss. Furthermore, it imparts suppleness and combability to the hair after dyeing.
