Abstract

To provide a hair dyeing composition that allows improved dyeing performance, which cannot be achieved by the conventional color treatment, and also allows beautiful coloration when mixed in a hair dye or a bleaching agent.SOLUTION: A hair dyeing composition uses a combination of HC blue 16 (HC Blue No. 16), basic yellow 87 (Basic Yellow 87), basic orange 31 (Basic Orange 31), and basic red 51 (Basic Red 51) and has a pH of 9.0 or more during its use, so that it can express a beautiful color without affecting the bleaching action of a hair dye.SELECTED DRAWING: Figure 1

Description

The present invention relates to hair dyeing compositions.

Hair dyes and hair dyes can be classified according to the dye used or the presence or absence of bleaching action on melanin.

Typical examples of hair dyes include acid dyes, basic dyes such as basic blue 99, basic brown 16, basic blue 75, basic blue 124, basic red 76, HC blue 2, HC yellow 2, HC Examples include semi-permanent hair dyes including HC dyes such as Yellow 4 and direct dyes such as nitro dyes.

Representative examples of hair dyes include permanent hair dyes comprising a first agent containing an alkali agent and an oxidation dye and a second agent containing an oxidizing agent.

Permanent hair dyes are excellent in that they penetrate deep into the hair, the color does not easily come off, and the hair dyeing effect lasts.

Therefore, in permanent hair dyes, a method has been proposed in which a direct dye is used in combination with an oxidation dye to obtain a brighter color (for example, Patent Document 1 below).

A method has also been proposed in which a permanent hair dye is blended with a specific acid dye to compensate for vivid colors that cannot be expressed with the oxidation dye of the permanent hair dye (for example, Patent Document 2 below).

However, acid dyes are highly adhesive to the skin and require treatment by a beautician. In addition, when blended in an alkaline formulation, there is a problem that there are few kinds of stable dyes and it is difficult to create color variations.

In addition, conventional hair color treatments must be in the acidic to neutral range due to the stability of dyes. However, it has disadvantages such as discoloration and light dyeing on hair.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a hair dyeing composition capable of vividly dyeing hair and expressing various color variations.

More preferably
The amount of the dye when used is more than 0.0% by mass and 1.0% by mass or less.

More preferably
It is characterized by containing one or more of tar dyes, HC dyes, basic dyes, and direct dyes.

More preferably
It is characterized by being used as a single item and having a pH of 9.0 or higher when used.

Furthermore, according to the hair dye composition of the present invention, not only does it not discolor even in a high pH range, but it is also unaffected by the bleaching action of the hair color. And by using the "three primary colors of color" selected from blue, red, and yellow, which are not affected by dyeing even in a high pH range, it is possible to express a variety of shades, and by adding orange, brown can be expressed. can be further emphasized.

Furthermore, according to the hair dyeing composition according to the present invention, the pH becomes 9.0 or more by being mixed with either the hair dye or the bleaching agent, thereby dyeing black hair while lightening it. You can create shades that could not be expressed with hair products.
