BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment composition for dyeing hair and at the same time performing permanent wave or straightening of hair, and more particularly to a hair treatment characterized in that a composition containing a dye is powdered. Agent composition.

[0002]

2. Description of the Related Art Conventionally, as a hair treatment composition for dyeing hair and performing permanent wave or straightening of hair at the same time, JP-B-46-38799 and JP-A-2-76807.
There was something like that shown in. These are prepared by mixing a solution obtained by adding an alkaline agent or the like to a mercapto compound or the like (hereinafter referred to as agent a) and a solution obtained by adding a surfactant or the like to an acid dye (hereinafter referred to as agent b). , Get a hair treatment. The hair treatment composition was of a system in which this hair treatment agent was applied to hair to be dyed and reduced, and then oxidized with bromate or the like. When hair dyeing, a permanent wave, or straightening of hair is performed using these hair treatment compositions, relatively good results can be obtained in terms of hair dyeing power and fastness.

[0003]

However, in the conventional hair treatment composition, since the acidic dye is provided as an aqueous solution, the acidic dye decomposes after long-term storage, resulting in a change in color tone and hair dyeing power. There was a problem such as a drop.
In addition, depending on the type of the acid dye, there is a limit to the solubility, and there are cases where only a low concentration of the acid dye can be obtained as the agent b. In such a case, as a result of mixing the agent b and the agent a, the concentration of the acid dye was too low, and sufficient hair dyeing power could not be obtained.

The present invention solves the above problems, improves the stability of the acid dye during the storage period, and further provides a hair treatment composition capable of obtaining a hair treatment agent containing a high concentration of the acid dye. The purpose is to

[0005]

Means and Actions for Solving the Problems The hair treatment composition of the present invention is summarized as a combination of the following (a) and (b). (A) Liquid A agent containing 1 to 15% by weight of one or more reducing agents selected from mercapto compounds, salts of mercapto compounds and sulfites. (B) 2 to 90% by weight of the acid dye, and the main component is galact
A solid B agent containing 5 to 95% by weight of a water-soluble polymer containing tomannan .

The agent A used in the present invention is an aqueous solution containing a reducing agent. The reducing agent reductively cleaves the -SS- bond of the cystine part of keratin, which is a hair tissue, to form a cysteine type, which facilitates the introduction of a dye, and at the same time enables a permanent wave treatment or a hair straightening treatment. Mercapto compounds used as reducing agents include thioglycolic acid, cysteine and acetyl cysteine. Further, salts and sulfites of the above mercapto compounds can be used as well. The agent A of the present invention contains 1 to 15% by weight of these reducing agents. When the content of the reducing agent is 1% by weight or less, sufficient hair dyeing or permanent wave effect cannot be obtained. When the content of the reducing agent is 15% by weight or more, the hair is damaged. The liquidity of the mixed solution of the agent A and agent B of the present invention is preferably pH 7 to 11. for that reason,
The agent A or the agent B contains a pH adjusting agent as required.
The pH adjuster causes the hair to swell and soften to facilitate the hair dyeing treatment. As the pH adjuster, inorganic alkalis, organic amines such as monoethanolamine, acids such as citric acid, and salts such as sodium citrate can be used. When the pH of such a pH adjusting agent is set to
It is contained in an amount of 7 to 11. When the liquidity of the mixed liquid of the agent A and the agent B is pH 7 or less, the swelling and softening of the hair may be insufficient, and when the pH is 11 or more, the hair may be damaged.

The agent B used in the present invention is a solid containing an acid dye and a water-soluble polymer compound as a thickener, and may be in the form of powder, granules or the like. The following acid dyes may be mixed. Red No. 2, No. 3, No. 102, No. 104 (1), 106
No. 201, No. 227, No. 230 (1), No. 230 (2), No. 231, 232, 401, 502
No. 503, 504, 506 Yellow Nos. 4, 5, 202 (1), 202 (2), 203, 402, 403 (1), 40
No. 6, 407 Green No. 3, 201, 205, 401, 402 No. 1, Blue No. 2, No. 202, No. 203, No. 205 Orange No. 205, No. 207, No. 402 Brown No. 201 Purple No. 401 Black No. 401 By mixing 2 to 90% by weight of the above acidic dyes alone or in combination, a color tone such as black, brown, red, blue and yellow is obtained. In addition, the water-soluble polymer compound is mixed in order to form a viscous hair treatment agent that does not drip when the above-mentioned agents A and B are mixed and applied. In order to obtain a more reliable permanent wave, only the agent A may be added later to the hair and allowed to permeate, so that it is not possible to add a large amount of the water-soluble polymer compound as the thickener to the agent A. Therefore, the required amount of the water-soluble polymer compound is added to the agent B. As the water-soluble polymer substance, a water-soluble polymer containing galactomannan as a main component, such as guar gum and locust bean gum, is used. For the agent B, one kind or two or more kinds are selected from the above water-soluble polymer compounds and mixed. The reason why the water-soluble polymer compound containing galactomannan as a main component, such as guar gum and locust bean gum, is blended is that when it is mixed with the agent A, it is easily dissolved and hardly becomes mamako . The compounding amount of the water-soluble polymer compound is 5 to 95% by weight with respect to the entire agent B.
Within the range, it is determined from the balance between the concentration of the acidic dye and the viscosity.

In addition to the above, agent B, a surfactant, a pH adjuster and a hair-growth component may be added to the agent B. As the excipient, starch, wheat flour, dextran, lactose, crystallized cellulose, calcium carboxymethyl cellulose, protein hydrolyzate, various amino acids and the like can be used. As the pH adjuster, citric acid, tartaric acid, sodium carbonate, sodium phosphate, sodium citrate and the like can be used. Enzymes, photosensitizers, sodium copper chlorophyllin, glycyrrhizinate, etc. can be added as hair-growth ingredients.

In the hair treatment composition of the present invention, it is preferable to use 1 to 40 parts by weight of agent B dissolved in 100 parts by weight of agent A. When the amount of the agent B is 1 part by weight or less, the concentration of the oxidative dye decreases. On the other hand, at 40 parts by weight or more,
It takes time to dissolve in the agent A, and the concentration of the reducing agent decreases.

Further, in the hair treatment composition of the present invention, after the above-mentioned agents A and B are mixed and applied to the hair, hair dyeing treatment, permanent wave treatment or curly straightening treatment is carried out, and then further. It is also possible to oxidize the hair by using the following agent C. (C) A liquid C agent containing 0.2% by weight or more of an oxidizing agent. As the oxidizing agent, one or more selected from oxidizing agents such as bromate, perborate and hydrogen peroxide can be used. Oxidation by the C agent makes the permanent wave and curly straightening treatment more reliable. If the amount of the oxidant compounded is 0.2% by weight or less, the oxidation of hair tends to be insufficient.

Further, as a method of simultaneously performing hair dyeing and permanent waving using the hair treatment composition of the present invention, for example, the following three types are possible. [Method 1] (1) The agent A and the agent B are mixed to prepare a hair dye, which is applied to the hair. (2) After leaving at 30 ° C. for about 30 minutes, wash with water. (3) Wipe off the water with a towel and wind the hair around the rod. (4) The agent A is applied, left at 30 ° C. for about 15 minutes, and then washed with water. (5) Apply the agent C and leave it at 25 ° C. for about 10 minutes. (6) Remove the rod from the hair and wash with water. [Method 2] (1) Mix the agent A and the agent B to prepare a hair dye solution, apply it to the hair, and wind it on a rod. (2) After leaving at 30 ° C. for about 30 minutes, wash with water. (3) Apply the agent C and leave at 25 ° C. for about 10 minutes. (4) Remove the rod from the hair and wash with water. [Method 3] (1) The agent A and the agent B are mixed to prepare a hair dye solution, which is applied to the hair. (2) After leaving at 30 ° C. for about 30 minutes, wash with water. (3) Wipe off the water with a towel. (4) Apply a small amount of oil. (5) Form a wave with a heated iron. (6) Apply the agent C and leave at 25 ° C. for about 10 minutes. (6) Wash with water.

Method 1 is the most practical method. Method 2
Although good results can be obtained, there are drawbacks such as contamination of the practitioner's fingers and winding of the rod. Method 3 is a method of simultaneously performing hair dyeing and iron perm. Incidentally, the simultaneous treatment of hair dyeing and curly hair straightening treatment can be carried out by the method of Method 2 which does not use a rod.

According to the present invention, it is possible to provide a hair treatment composition which enhances the stability of the acid dye during storage and can obtain a hair treatment agent containing a high concentration of the acid dye. It is considered that this is due to the following reasons. That is, by providing the acid dye in solid form,
The reactivity of the acid dye during the storage period can be lowered and its stability can be increased. Further, by dissolving the solid acid dye directly in the agent A, a hair treatment liquid containing a high concentration of the acid dye can be obtained as compared with mixing the aqueous acid dye with the agent A.

Table 1 shows the results of evaluation of Examples 1 to 5 and Comparative Examples 1 to 10 for hair dyeing power, waving power, and ease of mixing the agents A and B. In Table 1, the hair dyeing power was evaluated in the following two cases.

(I) Immediately after preparation of the hair treatment composition (ii) After storage of the hair treatment composition for 6 months at 40 ° C. Further, the Kilby method was used for the evaluation of the wave power. Moreover, each evaluation was performed by the following three-stage evaluation.

A: Excellent. ◯: Normal Δ: Slightly inferior As can be seen from Table 1, Examples 1 to 5 and Comparative Examples 1 to 5
In Comparative Example 6 , the hair dyeing power and the waving power immediately after production are superior to Comparative Examples 6 to 10 . In addition, Examples 1 to 5
In Comparative Examples 1 to 5 , the hair dyeing power did not change even after 6 months from the production, whereas in Comparative Examples 6 to 10 , the hair dyeing power after 6 months from the production was changed. Decrease is observed.

Further, in Examples 1 to 5, guar gum and locust bean gum containing galactomannan as a main component are used as the water-soluble polymer substance mixed with the agent B. Therefore, the ease of mixing Agent A and Agent B is comparative
It can be seen that it is superior to 1 to 5 .

As described above, according to the present embodiment, since the agent B containing the acidic dye is made into powder, the storage stability of the agent B is enhanced, and further, the agent A and the agent B are mixed with each other. It is possible to improve the concentration of the acid dye and obtain a hair treatment composition having excellent hair dyeing power. Further, a hair treatment composition having an excellent wave power can be obtained for the following reasons. That is, in the comparative example, a large amount of oils and fats such as higher alcohols are used in the agent A in order to give a proper viscosity to the mixed solution of the agent A and the agent B, whereby the reducing action is weakened and the wave force is reduced. It tends to decrease. On the other hand, in this example, it is not necessary to use these higher alcohols, and excellent waving force can be obtained.

Furthermore, since galactomannan is used as the water-soluble polymer substance to be blended with the agent B, the agent A and the agent B can be easily mixed without forming a muddy mixture. Because of this, hair
