[0002]

2. Description of the Related Art Conventionally, hair dyes using a tar-based acid dye have been widely used because they are superior in safety and convenience as compared with oxidative hair dyes.

[0003]

[Problems to be Solved by the Invention] However, hair dyes using a tar-based acid dye are not yet sufficiently satisfactory in the gloss and feel of hair after hair dyeing, and the viscosity due to aging changes. And there is a drawback that when applied to the hair, it drips and stains the ground and clothes.

An object of the present invention is to solve the above-mentioned problems and to provide a hair dye composition which is excellent in gloss and feel of hair and excellent in stability of viscosity even when a tar-based acidic dye is used. And

[0005]

Means and Actions for Solving the Problems The inventor of the present invention has proposed a method in which specific components are combined at a specific mixing ratio to obtain a specific pH.
The present inventors have found that the above-mentioned disadvantages can be solved by making the composition into a creamy form, and have completed the present invention.

That is, the hair dye composition of the present invention comprises (a) 0.01 to 2% by weight of a tar-based acidic dye, (b) 1 to 10% by weight of an aliphatic higher alcohol, and (c) nonionic surfactant. Or anionic surfactant
0.2 to 5 wt%, (d) 1 to 15 wt% aromatic alcohol and (e) hydroxycarboxylic cyclopropylmethyl cell row scan 0.5
It is characterized in that it contains 10% by weight and that the mixture has a pH of 2 to 5 and is creamy.

Hereinafter, the configuration of the present invention will be described in detail. (A) Tar-based acid dye 0.01 to 2% by weight The tar-based acid dye to be used in the present invention may be a conventionally known one, and can be appropriately selected according to a desired dyeing and coloring. May be used in combination of two or more. Specific examples of these tar acid dyes include:
For example, Red No. 102 (trisodium salt of 1- (4-sulfo-1-naphthylazo) -2-naphthol-6,8-disulfonic acid), Red No. 106 (9- (4′-sulfo-2′-sulfonium) Phenyl) -6-diethylamino-3- (N, N-diethylimino) -3-isoxanthene monosodium salt), Red No. 201 (4- (orthosulfoparatolylazo) -3-hydroxy-2-)

[0008] The content of the tar-based acid dye is 0.01
２2% by weight, preferably 0.05-1.5% by weight. When the amount of the tar-based acid dye is less than 0.01% by weight, the hair dyeing effect becomes insufficient. On the other hand, when the amount is more than 2% by weight, not only dyeing on the scalp and fingers is remarkable,
There are many discolorations. (B) Aliphatic higher alcohol 1 to 10% by weight Next, examples of the aliphatic higher alcohol include lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, and behenyl alcohol. These aliphatic higher alcohols may be used in combination of two or more.

The content of the higher aliphatic alcohol is 1 to 10
%, Preferably 4 to 8% by weight. If this content is less than 1% by weight, the viscosity of the composition as a whole will be low and there is a risk of causing the cream base to separate.
On the other hand, if it is more than 10% by weight, the viscosity of the whole composition becomes too high, making it difficult to apply the composition to the hair and making it impossible to perform a uniform hair dyeing treatment. (C) Nonionic or anionic surfactant

POE fatty acid amide POE stearic acid amide 13. Sucrose fatty acid ester The content of a nonionic surfactant or an anionic surfactant such as alkylamine oxide or dimethyllaurylamine oxide is 0.2 to 5% by weight. If the amount of the nonionic or anionic surfactant is less than 0.2% by weight, it is difficult to form a stable emulsion (cream). The stability of the agent and the feel of the hair deteriorate. Two or more nonionic or anionic surfactants may be used in combination.

The incorporation of a nonionic or anionic surfactant not only improves the emulsion stability of the cream base, but also suppresses the tar-based acidic dye from adhering to the scalp and fingers, as well as adhering it. It has the function of facilitating the removal of pigment.
In the present invention, if a cationic surfactant is blended, ionic bonding with the tar-based acidic dye is caused, and the dyeing power to hair is reduced. Therefore, it is desirable to avoid blending a cationic surfactant. (D) Aromatic alcohol 1 to 15% by weight In the present invention, the above-mentioned tar-based acidic dye, aliphatic higher alcohol, nonionic surfactant or anionic surfactant,
An aromatic alcohol is contained together with the cellulose derivative described below to enhance the dyeing property. Two or more aromatic alcohols may be used in combination.

The aromatic alcohol used in the present invention is preferably benzyl alcohol, phenethyl alcohol, phenylpropyl alcohol, cinnamon alcohol, anis alcohol, p-methylbenzyl alcohol, phenylethyl alcohol, phenoxyethanol, and particularly preferably benzyl alcohol.

The content of the aromatic alcohol is 1 to 15% by weight, preferably 3 to 10% by weight. When the content of the aromatic alcohol is less than 1% by weight, the coloring of the tar-based acidic dye to the hair becomes poor, and when it exceeds 15% by weight, the stability of the cream base is impaired. (E) hydroxypropyl methylcellulose 0.5 to
10 wt% in the present invention, further, as a cellulose derivative, containing human mud <br/> carboxypropyl methyl cellulose row scan. Hydroxycarboxylic cellulose is preferred because it has extremely excellent for viscosity stability.

The amount is 0.5 to 10% by weight. Preferably it is 1 to 8% by weight. If the amount is less than 0.5% by weight, the viscosity of the composition becomes low, which may cause separation of the cream base, danger of dripping when applied to the hair, and sufficient moisture retention for the hair. And the gloss and feel of the hair are poor.
On the other hand, when the content is more than 10% by weight, the viscosity of the composition becomes too high, the application is difficult to apply due to poor elongation when applied to hair, and the gloss and feel of hair are poor. (F) Cream of pH 2 to 5 In the hair dye composition of the present invention, the pH of the mixture is 2 to 5.
It is important that it is adjusted to 5 and adjusted to cream. The cream form includes a gel form or a paste form. As the pH adjuster, an organic acid such as citric acid or lactic acid or an inorganic acid such as hydrochloric acid is usually used. If the pH is less than 2, the dyeing on the scalp and fingers becomes remarkable, while if it exceeds 5, the dyeing power becomes weak. (G) Other Ingredients The hair dye composition of the present invention may contain, if necessary, oils and fats such as paraffins, lanolin derivatives, esters, silicone oils and animal and vegetable oils, amphoteric surfactants, Known compounding agents such as anti-dandruff agents, hair restorers, preservatives such as parabens, various protein hydrolysates, water-soluble polymers such as xanthan gum, pearlizing agents such as glycol esters, and fragrances can also be appropriately compounded.

As the solvent, lower alcohols such as ethanol, propanol, isopropanol and the like;
An organic solvent, for example, N-methyl-2-pyrrolidone, levulinic acid, ethylene carbonate and the like can also be appropriately blended. These may be used in combination of two or more. These have the effect of facilitating the dissolution of the aromatic alcohol in the cream base and increasing the dyeing power of the tar dye.

In the present invention, a stable cream base is prepared by the interaction of a predetermined amount of a tar-based acidic dye, an aliphatic higher alcohol, a nonionic surfactant or an anionic surfactant, a cellulose derivative and an aromatic alcohol. It is possible to prepare a hair dye composition that is maintained (therefore, there is no decrease in viscosity during storage) and has excellent coatability and hair dyeability. This excellent viscosity stability can be obtained only by a combination of these, and as will be compared later in the examples, it cannot be obtained without any of them.
Moreover, according to this composition, the gloss and feel of the hair are good. (H) Hair dyeing method After applying to hair and leaving it for 20 to 40 minutes, wash it with warm water,
Shampoo and dry with dryer. In addition, a slow dyeing type may be used. For example, by setting the leaving time after applying the hair dye solution to the hair to 5 to 10 minutes and repeating the hair dyeing two to several times, the gray hair can be gradually dyed black without being noticed by a person.
