Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition capable of easily dyeing hair without damaging the skin or hair and imparting smoothness and moistness to the hair.

[0002]

2. Description of the Related Art Conventionally, as a method for dyeing white hair, for example, (1) first, an oxidative dye mainly containing p-phenylenediamine is used, and usually after oxidative treatment with hydrogen peroxide,
A hair dyeing method using a two-component hair dye that uses a coupling agent,
(2) A method of temporarily attaching a dye to hair, and (3) a method of attaching a complex of a polyvalent metal salt and an organic compound which reacts with the polyvalent metal salt to produce color are known.

[0003]

However, the above method (1) has the advantages that the color tone after dyeing is good and that it does not fall off even if shampooed, but on the other hand, the hair and skin are treated with an oxidizing agent. Is susceptible to damage, is inconvenient to handle, and needs to be left for a certain period of time, so that it takes a long time to dye hair. (2)
The method (1) causes less irritation to hair and skin, but has the drawback of being easily removed by shampoo. Further, in the method (3), there is no damage to the skin or hair, and the hair dyeing property is better than that in the method (2), but in many cases, the polyvalent metal salt reacts with it. Since it is used together with an organic compound that develops color (Japanese Patent Laid-Open No. 53-52
633, Japanese Patent Laid-Open No. 64-90117, etc.),
There is a problem that the appearance of the hair dye is colored black and the commercial value is reduced.

Further, there is known a device for improving the hair dyeing property by using a dye and a polymer compound in combination, but none of them satisfies the smoothness and the moist feeling of the hair after dyeing. In addition, there is an example in which a dye is used in combination with a quaternized cationic surfactant such as stearyltrimethylammonium chloride, which is usually used in hair cosmetics for the purpose of improving the finish, but the adsorption of the dye on the hair is also seen. There is a difficulty in sexuality and the hair dyeing property is low.

The present invention has been made in view of the above problems, and provides a hair cosmetic composition which can easily and easily dye hair without damaging the skin or hair and imparts a smooth and moist feeling to the hair. With the goal.

[0006]

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventors have found that a dyeing component contains a predetermined amidoamine type surfactant, a predetermined guanidine derivative compound, or mono-N- By blending a long-chain acyl basic amino acid lower alkyl ester salt and adjusting the pH to a predetermined value, it is possible to easily and easily dye hair without damaging the skin or hair.
The inventors have found that a cosmetic for hair which gives the hair smoothness and moistness can be obtained, and completed the present invention.
