Description

  The present invention relates to a gel hairdressing cosmetic.

  Hairdressing cosmetics include liquid, gel, cream, wax, spray, foam and other dosage forms. Among these various dosage forms, the gel dosage form is characterized by having excellent spreadability on the hair. Such gel-like hairdressing cosmetics are usually blended with various thickeners in order to obtain a gel formulation. Among these thickeners, carboxyvinyl polymers and acrylic acid / alkyl methacrylate copolymers are widely used because of their excellent thickening effect. However, when a film-forming polymer is used as a hair styling agent, there is a problem that the hair does not fit well and the spreadability on the hair is poor.

  In order to solve such problems, attempts have been made to increase the familiarity with the hair and the spreadability on the hair. Specifically, hair cosmetics containing an amine oxide group-containing resin, a carboxyl group-containing thickening polymer, and one or more selected from the group consisting of polyhydric alcohols and polyether-modified silicones (for example, patent documents) 1), a hair cosmetic containing an amine oxide group-containing resin, a carboxyl group-containing thickening polymer, and one or more selected from the group consisting of a nonionic film-forming resin and an amphoteric film-forming resin (for example, Patent Document 2) has been proposed.

  However, carboxyvinyl polymers and acrylic acid / alkyl methacrylate copolymers have the disadvantage that the viscosity drops sharply due to salt contained in the palms and sweat of the fingertips. When hair is set using the palm or fingertips, there is a problem that cosmetics hang down from the palm or fingertips. Moreover, since the viscosity which is excellent in the spreadability cannot be maintained, there is a problem that the conformity to the hair and the spreadability on the hair are inferior, and thus, the sustainability of the hairstyle which has been adjusted is inferior.

JP-A-2005-232118 JP 2005-232119 A

  The present invention has been made in view of the above prior art, and does not sag from the palm or fingertip during hair styling, has good conformability to the hair and has good extensibility on the hair, and maintains the hair style that has been styled. It is an object of the present invention to provide a gel-like hairdressing cosmetic composition having excellent properties.
