Description

  The present invention relates to a hair treatment agent.

  After washing the hair with shampoo or the like, the protective layer on the surface of the hair may be lost, and finger passage may be poor. For this reason, hair treatment agents containing cationic surfactants such as quaternary ammonium salts have been widely used in order to impart slipperiness to the hair and improve fingering (JP 2013-170163 A).

JP 2013-170163 A

  When studies were made to improve the slipperiness of the hair, the feel of slipping to the hair tip, which cannot be obtained with a polymer compound, can be obtained by blending the powder raw material. However, when the powder raw material is blended with the hair treatment agent, there is a case where the powder moves to the hand when touching the treated hair.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a hair treatment agent that has a good feeling that the finger from the root of the hair to the hair tip slips and can suppress the feeling that the powder raw material moves. .

  The invention made in order to solve the above-mentioned problems is a hair treatment agent that is used after being applied to the hair, wherein a cationic surfactant, a higher alcohol and a powder raw material are blended, and octenyl succinate corn is used as the powder raw material. It is characterized by containing starch Al, kaolin or lauroyl lysine. The hair treatment agent may be a hair care agent.

  According to the hair treatment agent, by blending a specific powder raw material, finger passage from the root of the hair to the tip of the hair is good, and it is possible to prevent the finger from being caught by the tip of the hair, so from the root of the hair to the tip of the hair The feeling that the finger slides can be made uniform. Moreover, according to the said hair treatment agent, when the specific powder raw material is mix | blended, when the hair after processing is touched, the touch which a powder raw material moves to a hand can be suppressed.

  As said powder raw material, octenyl succinic acid corn starch Al is preferable. Thus, the low temperature stability of the said hair treatment agent can be improved by mix | blending octenyl succinic-acid corn starch Al.

  If the blending amount of octenyl succinate corn starch Al is 0.1% by mass or more, the viscosity of the hair treatment agent is lower than that of less than 0.1% by mass, and the hair finish after treatment tends to be lighter. . From this tendency, when it is desired to lighten the finish of the hair after the treatment, the blending amount of octenyl succinate corn starch Al in the hair treatment agent should be 0.1% by mass or more, and the finish of the hair after the treatment is improved. When it is desired to increase the weight, the blending amount is preferably less than 0.1 mass%.

  The hair treated with the hair treatment agent of the present invention has a good feeling that the finger from the root to the tip of the hair slips, and can suppress the feeling of hand-feeding of the powder material when touching the hair.

  The hair treatment agent of the present invention is used after being washed off after application to the hair. In the hair treatment agent, a cationic surfactant, a higher alcohol, and a powder raw material are blended with water (the blending amount of water is, for example, 60% by mass or more). The said hair treatment agent may contain the other arbitrary component in the range which does not impair the effect of this invention. Hereinafter, these components will be described in detail.

[Cationic surfactant]
A cationic surfactant is blended with a higher alcohol to bring the dosage form of the hair treatment agent close to cream or cream. Examples of cationic surfactants include di-long-chain alkyldimethylammonium salts such as distearyldimethylammonium chloride, dicetyldimethylammonium chloride, dicocoyldimethylammonium chloride; behenyltrimethylammonium chloride, behenyltrimethylammonium methosulfate, stearyltrimethylammonium chloride. Mono long-chain alkyltrimethylammonium salts such as stearyltrimethylammonium bromide and cetyltrimethylammonium bromide; long-chain alkoxyalkyltrimethylammonium salts such as stearoxypropyltrimethylammonium chloride; and ethyl sulfate lanolin fatty acid aminopropylethyldimethylammonium. The above di-long chain alkyldimethylammoni The number of carbon atoms of "long chain alkyl" in unsalted and mono-long chain alkyl trimethylammonium salts, for example, at 12 to 22.).
