Description

  The present invention relates to a hair cosmetic, and more particularly, a hair cosmetic that has a texture that stretches and conforms to the hair, gives the hair a moist feeling and a non-sticky finish, and has a good set retention. Regarding fees.

Conventionally, various film-forming polymers have been used in hair cosmetics for the purpose of setting hair. However, hair cosmetics that use these film-forming polymers alone stretch to the hair and feel bad, feel sticky when dried, feel stiff after drying, or flake and peel off. There were drawbacks such as causing Moreover, in order to improve such a fault, although the trial which combines a specific film forming polymer is made [refer patent document 1], the improvement of the further effect was desired.

  Hereinafter, the configuration of the present invention will be described in detail.

  Specific examples of the vinylpyrrolidone-hexadecene copolymer used in the present invention include Antalon V216 (manufactured by ASP Japan). Specific examples of the vinylpyrrolidone / eicosene copolymer used in the present invention include Antalon V220 (manufactured by ASP Japan).

  The compounding amount of the vinyl pyrrolidone / hexadecene copolymer and / or vinyl pyrrolidone / eicosene copolymer used in the present invention is 0.05 to 10.0% by mass (hereinafter abbreviated as%) based on the total amount of the hair cosmetic. It is preferably 0.5 to 5.0%. If the blending amount is less than 0.05%, the set retention may be insufficient, and if it exceeds 10.0%, the hair may be hardened, which is not preferable.

  As the anionic polymer compound (A) used in the present invention, a carboxyvinyl polymer and an acrylic acid / alkyl methacrylate copolymer are preferably used. Carboxyvinyl polymers and acrylic acid / alkyl methacrylate copolymers have the property of increasing viscosity by alkali neutralization. The carboxyvinyl polymer is mainly a polymer of acrylic acid, and is a synthetic polymer having a carboxyl group.

  The blending amount of the (A) anionic polymer compound used in the present invention is preferably 0.1 to 5.0% based on the total amount of the hair cosmetic. If it is within this range, a preferable viscosity for use can be obtained.

  The (A) anionic polymer compound used in the present invention is preferably used after adjusting the pH with an alkali, neutralizing it and increasing the viscosity. The alkali as the neutralizing agent is not particularly limited, and examples thereof include alkanolamines such as diisopropanolamine, triethanolamine and aminomethylpropanol, ammonia, potassium hydroxide, sodium hydroxide and the like.

  Specific examples of the carboxyvinyl polymer used in the present invention include “sinteral” series [manufactured by 3V SIGMA], “carbopol” series [B. F. Goodrich, Inc.] and the like.

  Specific examples of the acrylic acid / alkyl methacrylate copolymer used in the present invention include “Pemulene” series [B. F. Goodrich, Inc.] and the like.

  As the (B) polysaccharide and its derivative used in the present invention, one or more selected from the group consisting of xanthan gum, locust bean gum, gua gum, and tragacanth gum is preferably used. [Made by KELCO, USA], Gel-up SA-3C [Made by San-Ei Gen F.F.I.], Sanace C [Made by San-Ei Gen F.F.I.] and the like.

  As a compounding quantity of (B) polysaccharide and its derivative used for this invention, 0.01 to 5.0% is preferable on the basis of the total amount of hair cosmetics, Most preferably, it is 0.1 to 2.0%. It is. If it is within this range, a preferable viscosity for use can be obtained.

  The hair cosmetic composition of the present invention is preferable because it further contains a protein, so that an effect of imparting a smooth feel to the hair can be obtained and the finish is further improved.

  The protein used in the present invention is not particularly limited as long as it is usually used in cosmetics, but collagen protein, elastin protein, silk protein, keratin protein, pearl protein, soybean protein, wheat germ protein, and hydrolysis thereof The product or derivative is preferable because it has an effect of imparting a smooth feel to the hair. Examples of these proteins include hydrolyzed collagen, hydrolyzed elastin, water-soluble elastin, water-soluble collagen, hydrolyzed silk, silk extract, soybean peptide, wheat peptide, wheat germ extract and the like.
