Description

  The present invention relates to hair cosmetics that do not wash away (particularly treatments that do not wash away).

  As hair cosmetics that are not washed away, those in which silicone is blended for the purpose of imparting a slipperiness to the hair are known.

  However, since silicone has build-up properties (that is, accumulation on the hair surface), repeated use of silicone-containing hair cosmetics gradually causes hair to become stiff and itchy and difficult to blow. was there. In addition, when chemical hair treatment (wavebing, coloring, etc.) is performed, there is a problem that it is difficult for a drug (wave agent, hair dye, etc.) to penetrate into the hair.

  In order to solve these problems, Patent Document 1 proposes a “silicone-like feel-imparting agent” as a silicone substitute.

JP-A-2005-306786.

  However, the silicone-like feel-imparting agent can impart a touch similar to silicone in a hair cosmetic to be washed away, but cannot be sufficiently imparted in a hair cosmetic that is not washed away.

  In view of the above circumstances, the present invention can impart slipping and the like without using silicone, and as a result, can be easily blown, and can also impart other touches (softness, moist feeling, clumping, etc.), non-washing hair The purpose is to provide cosmetics.

  In order to achieve the above object, the inventors of the present application diligently studied, and as a result, they found that if a cationized oligosaccharide and hydroxyethyl chitosan were used in combination, the present invention was achieved.

  That is, the present invention provides a hair cosmetic that does not wash away, characterized by containing 0.005 to 0.2% by weight of a cationized oligosaccharide and 0.00002 to 0.001% by weight of hydroxyethyl chitosan. To do.

  According to the present invention, there is provided a hair cosmetic that does not wash away, which can impart slip and the like to the hair without using silicone, and as a result, can be easily blown, and can also impart other touches (softness, moist feeling, tightness, etc.). Can be provided.

Hereinafter, this invention is explained in full detail based on embodiment.
The non-washing hair cosmetic of the present invention contains a cationized oligosaccharide. Specific examples of the cationic group in the cationized oligosaccharide include an alkyl quaternary ammonium group, a hydroxyalkyl quaternary ammonium group, an acylalkyl quaternary ammonium group, and the like. Specifically, the polymerization degree of the sugar monomer in the cationized oligosaccharide is preferably 2 to 250.

Preferably, the cationized oligosaccharide is a stearyl dihydroxypropyl dimonium oligosaccharide.

  The hair cosmetic composition that does not wash away according to the present invention contains hydroxyethyl chitosan. Of the water-soluble chitosans, only hydroxyethyl chitosan specifically exhibits a touch similar to that of silicone when used in combination with a cationized oligosaccharide, and is not expressed in other water-soluble chitosans (for example, hydroxypropyl chitosan).

  As the other additives, a preservative, a pH adjuster, a fragrance and the like may be added to the non-washed hair cosmetic of the present invention.

  In the composition of the hair cosmetic composition of the present invention that does not wash away, the cationized oligosaccharide is 0.005-0.2 (preferably 0.01-0.1) weight, and the hydroxyethyl chitosan is 0.00002-0.001. (Preferably, 0.00005 to 0.0006)% by weight. Moreover, in an additive, surfactant is 0.01-5.0 (especially 0.1-3.0) weight%, and an oil-based component is 0.01-20.0 (especially 0.1-10.0). The weight percent and the polyhydric alcohol are preferably 0.01 to 10.0 (particularly 0.05 to 3.0) weight percent, respectively.

  If there is too little cationized oligosaccharide or hydroxyethyl chitosan, hair slip and other feelings (softness, moist feeling, clumping, etc.) may not be expressed. On the other hand, if there are too many cationized oligosaccharides, the hair may have hardness, poor cohesion, reduced slip, and the like. If there is too much hydroxyethyl chitosan, the moist feeling may be reduced, sticky, or caught.

  Examples of the “hair cosmetic” in the non-washed hair cosmetic of the present invention include treatments, hair water, hair oil, hair cream, hair wax, hair gel, hair milk, hair foam and the like. Preferably, the hair cosmetic that does not wash away is a treatment that does not wash away.
