Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a hair cosmetic composition, and more particularly to a hair cosmetic composition that imparts suppleness, moistness and smoothness to the hair and provides a good feeling of use and finish. Is.

[0002]

2. Description of the Related Art Heretofore, in hair cosmetics, various components have been tried to be blended for the purpose of imparting conditioning effects such as suppleness and smoothness to hair. For example, a cationic surfactant, an oil agent such as silicone oil, a polymer substance and the like have been appropriately blended according to the purpose.

[0003]

Cationic surfactants are used for the purpose of imparting flexibility and antistatic properties to hair, but there is a limit to the amount blended from the viewpoint of safety. However, there was a limit to the manifestation of the effect. The oil is
It imparts luster and smoothness to the hair and improves the hair styling property. However, depending on the type of oil agent, there are cases where desensitization in sensory characteristics such as stickiness and heavy finish occur. Further, when a nonionic surfactant is used for stably blending an oil agent, there are drawbacks such that the effect of the above-mentioned cationic surfactant is reduced. In polymeric substances, it has a function of contributing to the moisturizing effect on hair and the stability of the system, but depending on the type, it forms a film and becomes stiff, or it feels heavy depending on the degree of polymerization, so it is light There was a drawback that it was difficult to obtain a supple conditioning effect. Therefore, it has been desired to develop a hair cosmetic composition which is excellent in conditioning effect and has a good feeling in use.

[0004]

In view of the above-mentioned circumstances, the inventors of the present invention have as a result of earnest research, and found that a hair cosmetic having the following constitution using polyethylene glycol having a specific degree of polymerization can solve the above-mentioned problems. The present invention has been completed.

Yes.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The component (A) used in the present invention is polyethylene glycol having an average molecular weight of 100,000 or more and less than 500,000. If the average molecular weight of polyethylene glycol is less than 100,000, sufficient smoothness cannot be obtained, and if it is more than 500,000, the feel becomes too heavy and suppleness cannot be obtained. Examples of commercially available products include Polyox WSR series (manufactured by Union Carbide Co.) and the like. The content of the component (A) is 0.0
It is 1 to 2% by weight (hereinafter, simply referred to as "%"), and more preferably 0.05 to 1%.

The component (B) used in the present invention is a nonionic surfactant. The nonionic surfactant is not particularly limited, but specifically, sorbitan fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester, polyoxyethylene fatty acid ester, polyethylene glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxy Examples thereof include ethylene alkyl phenyl ether, polyoxyethylene castor oil, polyoxyethylene hydrogenated castor oil, and fatty acid alkylolamide. The content of the component (B) is 0.1 to 10
%, And more preferably 0.5 to 5%.

The component (C) used in the present invention is a bird 2
-Glyceryl ethylhexanoate, 2-ethylhexanoic acid
Cetyl, isopropyl myristate and palmitate
It is one or more selected from octyl. The content of the component (C) is 0.1 to 30%, more preferably 0.5 to 10%.

Examples of the polyhydric alcohol as the component (D) used in the present invention include glycerin, propylene glycol, dipropylene glycol and 1,3-butylene glycol. The content of component (D) is 0.1
To 30% by weight, more preferably 0.5 to 20%
Is.

In addition to the above essential components, the hair cosmetic composition of the present invention can further exhibit the effects of the present invention if it contains 2% or less of a cationic surfactant as the component (E). The cationic surfactant is not particularly limited, but quaternary ammonium salts such as monoalkyltrimethylammonium salt and dialkyldimethylammonium salt are preferable, and specifically, stearyltrimethylammonium chloride, behenyltrimethylammonium chloride,
Examples thereof include distearyldimethylammonium chloride and dibehenyldimethylammonium chloride.

In addition to these components, the hair cosmetic composition of the present invention contains water-soluble polymers, silicone derivatives, higher alcohols, lower alcohols, fragrances, preservatives, ultraviolet absorbers, antioxidants, bactericides and cosmetic ingredients. And the like can be used as long as the effects of the present invention are not impaired.

The hair cosmetic composition of the present invention can be used as a hair rinse, a hair conditioner, a hair pack, a hair cream, a hair lotion, a treatment mousse, etc., and can be used in various forms such as liquid, emulsion, cream and gel. It can be carried out. The method of use can be either a type of applying on hair and then washing off, or a type of applying on dry hair, but the latter is more preferable.
