Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hair cosmetic composition (hairdressing composition), more specifically a polyoxyalkylene compound, a hair-fixing polymer compound and polyethylene glycol. The present invention relates to a hair cosmetic having excellent properties and capable of imparting smoothness (smoothness) and good feel to the hair after application.

[Conventional technology]

Conventionally, various hair cosmetics such as set lotion, hair spray, hair mist and hair foam have been used for the purpose of making hairstyle easy and making hairstyle last longer. Polymer compounds for immobilization (hereinafter mainly referred to as "polymer compounds")
Was dissolved in an appropriate solvent such as water, a lower alcohol, or a mixed solvent of water and a lower alcohol. Then, the hair mist is used as it is, and the solution is mixed with an appropriate liquefied gas as a propellant and used as an aerosol is a hair spray. The hair foam is formed into the shape.

Further, in recent years, along with the diversification and individualization of hairstyles, hair-type cosmetics that contain a large amount of polymer compounds to set hair more firmly have been demanded.

[Problems to be Solved by the Invention]

However, the conventional hair cosmetics as described above have the following drawbacks when used.

Since the surface tension of the polymer compound is higher than the critical surface tension of the hair, the polymer compound becomes small lumps and adheres to the hair like islands and does not form a uniform film.

As a result of the polymer compound sticking to the hair in an island shape, the curl holding power, particularly the curl holding power under high humidity, is poor, and the feel of the hair is deteriorated.

Therefore, conventionally, for the purpose of eliminating the above-mentioned drawbacks, the hair cosmetics described above have been added and blended with cosmetic oils and fats, silicone oils and surfactants. The hair cosmetic thus obtained is
It had drawbacks such that the oily feeling became strong, and it became sticky and the hair styling was poor.

Further, a hair styling material containing a polyoxyalkylene compound has been developed as a hair styling material which is supple and does not have a sticky feeling and has a sufficient hair styling power (Japanese Patent Laid-Open No. 60-243012), but the smoothness of the hair is known. There is a demand for an improved hair styling product.

Therefore, an object of the present invention is to provide a hair cosmetic composition capable of imparting smoothness (smoothness) and a good feel to the hair after application without impairing the hair styling properties of conventional hair cosmetic compositions. .
