Abstract

PROBLEM TO BE SOLVED: To obtain an acidic hair dye composition which scarcely causes the discoloration of hair, when the hair is dyed and then washed, and thereby has excellent color fastness. SOLUTION: This hair dye composition comprising an acidic dye and an acid is characterized by formulating one or more acidic dyes selected from Green No.204, Red No.230 (1), and Yellow No.202 (1) in an amount of 0.1 to 15% based on the total amount of the acidic dyes in the hair dye composition.

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, and more particularly, to an acidic hair dye which has little color loss during hair washing after dyeing and is excellent in dyeing fastness.

[0002]

2. Description of the Related Art Generally, an acidic hair dye comprises an acidic dye, an organic solvent, an acid, a thickener and water, and dyes the hair by adsorbing the acidic dye near the surface of the hair.
This type of hair dye is also called a semi-permanent hair dye, and the characteristic feature of the hair after dyeing is that the dye gradually flows out by shampooing or the like, and discolors within a few weeks at the earliest.

[0003]

Particularly, immediately after dyeing hair,
Since many dyes are physically adsorbed on the hair surface, there is a phenomenon that the dye flows out at the time of washing the hair and the color of the wash liquid becomes very dark. The same phenomenon may occur when sweating. This washing solution stains the towel when it is towel-dried after washing the hair, and the dye spilled by sweat stains the collar of the clothes and the hat. In addition, many consumers strongly felt that the color would peel off immediately, despite the fact that the color of the washing liquid was dark, so that the actual color of the hair would not fade.

[0004]

Means for Solving the Problems Under the circumstances, as a result of intensive studies by the present inventors, as a result of adding a specific acid dye in a specific ratio, the dyeing fastness of hair is improved, and the hair is washed during washing. Coloring of liquid or sweat can be reduced,
As a result, they have found that stains around towels, clothes collars or hats can be prevented, and the present invention has been completed.

That is, in a hair dye composition containing an acid dye and an acid, the acid dyes of the following groups (A) and (B) are blended, and (A) is added to the total amount of the acid dye in the hair dye composition. ) A hair dye composition, wherein the compounding ratio of the acid dye of the group is 0.1 to 15%. (A) Green No. 204, Red No. 230 (1) and Yellow 20
One or more acid dyes (B) selected from No. 2 (1) and other acid dyes.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The acid dye of the present invention is a ministerial ordinance that stipulates tar dyes that can be used in pharmaceuticals (Showa 4).
It is an acid dye among the tar dyes described in the 1st Year Health and Welfare Ordinance No. 30).

The dyes of group (A) are one or more acid dyes selected from green No. 204, red No. 230 (1) and yellow No. 202 (1) described in the above-mentioned Ministerial Ordinance, and (B)
The group is other acid dyes.

[0008] Usually, a dye composition of the group (B) is used to prepare a hair dye composition having a desired color tone and hair dyeing power. By mixing the (A) group acid dye here, the dyeing fastness is improved without impairing the original color tone and hair dyeing power, and the coloring of the hair wash and sweat is suppressed, and the stains on towels and clothes are prevented. You will be able to prevent it.

[0009] Although the action factor is not clear about these effects, especially the effect of being excellent in dyeing fastness, as for the effect of suppressing the coloring of hair washing liquid or sweat, the color of the washing liquid is added by adding the acid dye of the group (A). It is thought that this may be due to the visual effect that appears to be thin (hypercolor effect). The reason why the acid dyes of group (A) have such an effect is
After all it is unknown. Further, this effect can be further enhanced by appropriately selecting the acid dye of the group (A) according to the color tone of the target hair dye. For example, red 203 (1) and yellow 202 (1) are suitable for warm colors such as orange, and green 204 is suitable for cold colors such as blue and low saturation such as brown and black. Tend to be. Naturally, the acidic dyes of the group (A) can be used by appropriately combining two or more kinds according to the color tone of the target hair dye.

The amount of the acid dye of the group (A) is 0.1 to 15 of all the acid dyes contained in the hair dye composition.
%, If it is less than 0.1%, a sufficient effect cannot be obtained, and if it exceeds 15%, no further effect can be obtained. On the contrary, the acid dye of the (A) group does not give a hair color tone. And may not be able to obtain a desired color tone, which is not preferable.

As the other acid dyes of the group (B), the acid dyes other than the group (A) described in the above-mentioned Ministerial Ordinance are applicable, but particularly blue No. 1, red No. 102, red No. 106,
Red 504, orange 205, yellow 4, yellow 2
03, yellow 403 (1), green 201, brown 20
One or more selected from No. 1, purple No. 401 and black No. 401 are preferable in terms of color vividness and good color development.

Various acid dyes were added to this base formulation to prepare Examples and Comparative Examples by a conventional method. Table 1 of each prescription
~ 3. The comparative example with a is an example not containing the acid dye of the (A) group, and the comparative example with b is an example in which the acidic dye of the (A) group is excessively blended.

<Hair dyeing test> An appropriate amount of the hair dye composition is uniformly applied to a hair bundle (white-haired human hair and goat hair), wrapped in a wrap, left at 45 ° C for 15 minutes, and then at room temperature for 5 minutes. After standing, it was washed with a normal shampoo and dried. The hair color tone and the degree of dyeing of this hair bundle were visually evaluated according to the following criteria.・ Compared with the prescription examples of the hair dye color tone (A) group which does not contain the acid dye, ○: the color tone does not change, △: the color tone changes slightly, ×: the color tone varies greatly. ・ Hair dyeing power (A) group Compared to the prescription example in which no acid dye was mixed, the hair dyeing power was improved. O: The hair dyeing power was about the same, the hair dyeing power was slightly weak, and the hair dyeing power was clearly weak.

<Fastness test> The dyed hair bundle is 5 days later.
1% sodium lauryl sulfate aqueous solution (500 m
The hair bundle was then thoroughly washed with water and air-dried. The degree of fading of the hair bundle at this time was compared with that of the hair bundle before treatment, and the color strength of the solution was visually evaluated according to the following criteria. Solution coloring (A) compared to the formulation example in which the acid dye is not blended: ◎: Solution coloring is obviously light ○: Solution coloring is slightly light △: Solution coloring is similar ×; The solution becomes darker in color / fading of the hair bundle ◎; almost no fading ○: little fading △: fading slightly large ×; fading large

The results are shown in Tables 1 to 3.

[Table 3]

As described above, in the examples, by containing the acid dye of the group (A), it is possible to suppress the outflow of color when the hair gets wet without changing the desired hair dyeing power and color tone. It was a hair dye composition which could be produced and which is less likely to stain the collar of clothes or the hat.

When the acid dye of the group (A) is excessively blended,
It was pointed out that although it has an effect on the fading surface, it may affect the color tone and hair dyeing power at the time of dyeing hair.
