Description

  The present invention relates to a hair cosmetic, and more particularly, it contains a propylene oxide polymer, silicic anhydride, and an extender powder. It is related with the hair cosmetics which have the outstanding set holding power which the hairstyle which arranged is made possible and lasts for a long time.

  Conventionally, preparations such as hair liquids, hair creams, hair tics, pomades, hair sprays, hair foams, set lotions, blow lotions, etc. have been used as hair cosmetics. These hair cosmetics mainly consist of oils and waxes. , An oily component such as a polyoxyalkylene alkyl ether compound or its phosphate, and a hair styling component, and an anion such as an alkyl acrylate / diacetone acrylamide copolymer or a vinyl acetate / crotonic acid copolymer Polymer compounds, amphoteric polymer compounds such as acetic acid amphoteric compounds of dialkylaminoethyl methacrylate polymers, octylacrylamide acrylate / hydroxypropyl acrylate / butylaminoethyl methacrylate copolymers, vinylpyrrolidone / dimethylaminoethyl methacrylate Cationic polymer compound such as quaternary compound is a film-forming polymer, such as those with hair fixative components. Hair liquids, hair creams, hair tics, pomades, etc. that use oily ingredients as hair-styling ingredients have drawbacks such as stickiness during use, and the finish gives a heavy and dirty impression, and hair that uses film-forming polymers as hair-styling ingredients Spray, hair foam, set lotion, and blow lotion form a hard film on the hair surface, and the hair styling retention effect is good, but the hair becomes glossy after hair styling, is stiff, flaking (the film peels off) There are disadvantages such as white granularity).

  In particular, in recent years, it has become popular for young people to make hair or to make casual styles, and gel-like hair cosmetics and waxes are used to create these hairstyles. Gel hair cosmetics generally contain a carboxyvinyl polymer as a thickener and a nonionic polymer compound as a hair styling base, but have poor hair retention under high humidity conditions. Since there are drawbacks such as flaking, various proposals have been made in the past, including blending polyvinylpyrrolidone with a specific molecular weight, combining polyvinylpyrrolidone and hydroxypropyl guar gum, and combining amphoteric polymers with cellulose derivatives. Various hair cosmetics have been proposed such as combining (see, for example, Patent Documents 1 to 3), but these are impaired in gloss, increased stickiness, impaired storage stability, etc. There were drawbacks. The wax is used for the purpose of higher setting power and arranging power, and for example, a hair wax (for example, see Patent Document 4) containing 12-hydroxystearic acid and an alkali agent is disclosed. In the method, although there is little stickiness and an effect of good elongation can be obtained with a smooth touch, there is a limit when trying to obtain a higher setting force, and there is also a limit on the set retention.

  Propylene oxide polymerization has been used for hair liquids and the like for a long time because of its stickiness, but it has been demanded to have a good feeling of use that does not stick while maintaining the set power due to stickiness. Hair cosmetics (for example, see Patent Documents 5 to 7) in combination with a surfactant, hydroxyethyl cellulose and the like have been proposed. However, even with these hair cosmetics, it has been very difficult to obtain a hair cosmetic with excellent arrangement and excellent style retention. From these facts, the development of hair cosmetics with excellent set-holding power that has good stretchability, little stickiness, enables hair arrangement with high setting power on the hair, and the arranged hairstyle lasts for a long time is strong. It was desired.
