Description

  The present invention relates to a hair cosmetic.

  Hair rinses, hair treatments, hair packs, hair masks, and the like have been used as invasion care measures for excessively damaged hair. In these compositions, a cationic surfactant having a hair softening effect as a main component is blended, and higher alcohol, liquid paraffin, ester oil, sterols, lipids, silicone oil, Peptides or proteins derived from shellfish, fish, silk, plants, seaweed, etc., or derivatives thereof are blended. It is known that the conditioning effect can be obtained by physical adhesion, charge adsorption, or permeation of these components on the hair surface even after rinsing with hot water or water.

  Conventionally, starch and derivatives thereof have an excellent feeling of use, and are therefore incorporated in many cosmetics and compositions regardless of the site of use. For example, it is known to improve the temporal stability of emulsifiers and oils in an emulsified composition (Patent Document 1). In particular, it is known that when starch phosphate (starch phosphate) is blended in a hair cosmetic, an effect of smoothing out hair tangles can be obtained (for example, Patent Document 2). Furthermore, by combining with a cationic polymer or a specific carboxylic acid ester, it is said that a soft feel to the hair and a feel free of residue on the hair are imparted (Patent Documents 3 and 4). Moreover, the stable treatment which suppressed irritation | stimulation expression by combining with a cationic surfactant is proposed (patent document 5).

  On the other hand, hair cosmetics containing branched polyglycerol-modified silicone can impart smoothness, flexibility and luster to hair with a small amount of use without stickiness, and can reduce hairiness and achieve good cohesive hair. Known (Patent Document 6).

  However, in conventional hair cosmetics, tangling is eliminated after use, and a finished feeling such as slipperiness, cohesiveness, and flexibility can be obtained, but it is not sufficient to obtain the same feel even during use, particularly during rinsing. There wasn't.

  Accordingly, the object of the present invention is to provide a smooth, smooth and smooth fingering feeling when used, especially when rinsing, and to smooth and smooth the fingertips after finishing without causing any stiffness. An object of the present invention is to provide a hair cosmetic that can provide a feeling and can maintain the above-mentioned effects even in long-term continuous use.
