Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hair dye composition, and in detail:
The present invention relates to a hair dye composition that is less irritating to the skin and provides good gloss and feel to the hair.

[Prior art and its problems] Conventional hair dyes include, for example, colorless low-molecular oxidation dyes that penetrate into the hair and undergo oxidative polymerization in the hair to produce pigments and dye spots. Oxidative hair dyes are known, and are generally widely used because they can produce various color tones and have excellent hair dyeing power. Semi-permanent hair dyes that dye hair by solvent dyeing using acidic or basic dyes are also useful hair dyes for people who cannot use oxidative hair dyes due to allergies.

However, especially in the case of oxidative hair dyes, there is a tendency for hair to be damaged and the shine and feel of the hair to be poor after treatment. It is also irritating to the skin and may have an adverse effect on the scalp.

Conventionally, methods of blending various additives have been proposed to alleviate these drawbacks, but so far,
I have not found anything that is sufficient.

[Problems to be solved by the invention and means for solving the problem] In view of the above-mentioned circumstances, the present inventor has aimed to obtain a hair dye composition that causes almost no irritation to the skin when using the hair dye and does not damage the hair after treatment. As a result of various studies, it was discovered that the object of the present invention could be achieved by using three specific compounds such as amphoteric surfactants in combination, and the present invention was completed.

That is, the gist of the present invention resides in a hair dye composition containing an amphoteric surfactant, a branched higher alcohol, and an alkyl ether type nonionic surfactant together with a dyeing component.

Hereinafter, the configuration of the present invention will be explained in detail.

The dyeing component targeted by the hair dye of the present invention is not particularly limited, and may include various types of known hair dyes. A typical example is an oxidative hair dye consisting of a second agent. In this case, the oxidative dye intermediate of the first agent of the oxidative hair dye is usually phenylene diamines, aminophenols, tolylene diamines, aminonitrophenols, diphenylamines, diaminophenylamines, N - Phenylphenylenediamines, diaminopyridines, etc. or salts thereof, and mixtures thereof, and the blending amount thereof is, for example, 0.0% based on the total weight of the first agent.
It is about 1 to 10% by weight. Further, in the first agent, for example, resorcinol, birogallol, catechol, meta-aminophenol, meta-phenylenediamine, etc. can be blended as a coupler. Furthermore, compounds listed in the "Standards for Hair Dye Raw Materials" (revised third edition, May 1985, published by the Japan Hair Color Industry Association) can be blended. If necessary, moisturizers such as glycerin and propylene glycol, surfactants such as oil-based or anionic surfactants such as lanolin, squalane and liquid paraffin, cationic surfactants and nonionic surfactants, sulfites, Stabilizers such as ascorbic acid, thickeners such as carboxymethylcellulose, alkali agents such as ammonia and alkanolamines, fragrances, and the like may be appropriately blended.

On the other hand, examples of the second agent oxidizing agent include oxidizing agents such as hydrogen peroxide and urea peroxide. In addition, the second agent may contain, for example, stabilizers such as phenacetin and EDTA, oils and fats such as paraffin, higher alcohols, surfactants, acids, phenacetin, etc.
H regulators, fragrances, and the like can be added as appropriate. The first agent and the second agent are usually mixed and applied to the hair immediately before use.

In the present invention, three types of surfactants are used: an amphoteric surfactant, a branched higher alcohol, and an alkyl ether type nonionic surfactant.
It is an essential requirement that all two be used together.

In short, as is clear from the data of Examples and Comparative Examples described below, if even one of these compounds is missing, the object of the present invention cannot be achieved.
