Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a dye component for hair coloring, a dye precursor for hair coloring, a keratin reducing agent, a hair softening agent, a hair firmness / stiffening agent, a hair softening agent and the like. The present invention relates to a hair cosmetic which is suitable as a hair dye, a curling agent, a hair conditioner, etc., in which the penetration rate of various active ingredients into hair is high, the penetration amount is large, and the irritation to the skin is extremely small.

[0002]

BACKGROUND OF THE INVENTION Hair cosmetics are used in various applications such as hair dyes, shampoos, rinses, treatments, permanent waving agents, firming and stiffening agents, and hair makeup agents. Cosmetics. In these hair cosmetics, if the compounded various active ingredients do not penetrate and reach the hair, the effects of the active ingredients are weakly expressed, and it is difficult to sufficiently achieve the purpose of use.

[0003] Therefore, as a penetration enhancer of various active ingredients blended in the above hair cosmetics, for example, benzyl alcohol and benzyloxyethanol (JP-A-4-6
Aromatic alcohols, such as N-alkylpyrrolidone, 1-butyl-2-imidazolidinone (described in JP-A-10-1426), and the like.

[0004] However, these penetration enhancers have the drawback that their penetration enhancer action is not yet sufficient, and that they sometimes develop irritation, and thus do not have the drawbacks of the conventional penetration enhancers. That is, there is a demand for the development of a penetration enhancer that is not irritating and has excellent penetration promoting action.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been made in consideration of the above circumstances.
It is an object of the present invention to provide a hair cosmetic composition which is excellent in the penetration rate and amount of various active ingredients such as a stiffening agent into hair, which satisfactorily expresses the effects of the active ingredients, and which causes minimal irritation to the skin.

[0006]

Means for Solving the Problems and Embodiments of the Invention The present inventors have made intensive studies to achieve the above object, and as a result, focused on glyceryl ether compounds having good properties as oil agents, humectants and the like. By blending a glyceryl ether compound represented by the following general formula (1) into hair cosmetics, such a glyceryl ether compound acts as a penetration enhancer and is conventionally used as apparent from the examples described below. Compared to the penetration enhancer of the active ingredient, when the various active ingredients in the cosmetic are penetrated into the hair, the penetration speed is extremely high, and the penetration amount is remarkably improved. The present inventors have found that a hair cosmetic composition that can strongly exert the action and effect of the components and that causes minimal irritation to the skin can be obtained, thereby completing the present invention.

[0007] A detergent composition and a dye composition containing a glycerin derivative are disclosed in JP-A-5-32538,
Japanese Patent Application Laid-Open Nos. 5-246683 and 11-43698 disclose that a specific glyceryl ether compound represented by the above formula (1) is blended into a hair cosmetic as a penetration enhancer, It is a new finding of the present inventor that it acts as a penetration enhancer to the hair and exhibits the above-mentioned special effects.

[0008] Therefore, the present invention provides that the composition contains one or more compounds represented by the following general formula (1) as a penetration enhancer in an amount of 0.1 to 50% by weight based on the total amount of the cosmetic. A hair cosmetic is provided.

Hereinafter, the present invention will be described in more detail. The hair cosmetic composition of the present invention contains a specific glyceryl ether compound, and the compound acts as a penetration enhancer to provide various effective ingredients in the composition. It improves the permeation rate and permeation amount of the component.
