Description

  The present invention relates to a hair cosmetic that is excellent in hair conditioning effects and scalp / hair moisturizing properties, and also has an effect of suppressing scalp dandruff and itching.

  In recent years, coloring, daily hair washing, hair dryers, and the like have increased, and the scalp and hair have been physically and chemically damaged. Furthermore, the effects of increased stress and changes in dietary habits are increasing. Such damaged hair becomes dry and rusty, and looks and feels deteriorate. In addition, the number of people suffering from scalp troubles is increasing regardless of gender. Typical symptoms include dandruff and itching, which are no longer a problem for some people. Therefore, there is a demand for a hair cosmetic that exhibits an effect of suppressing scalp trouble and has an excellent hair conditioning effect.

  In order to prevent or reduce scalp dandruff, itching, etc., it is known that hydroxypyridone compounds, pyrithione compounds, miconazole and its salts, and bactericides such as sulfur are incorporated into hair cosmetics as anti-dandruff agents. (Patent Document 1: Japanese Patent Laid-Open No. 54-98343, Patent Document 2: Japanese Patent Laid-Open No. 56-150008, Patent Document 3: Japanese Patent Laid-open No. 57-209210, Patent Document 4: Japanese Patent Laid-Open No. 08- No. 3042, Japanese Patent Laid-Open No. 11-269043). In addition, it has also been proposed as a cosmetic that gives a moisturizing effect to the skin and hair (see Patent Document 6: Japanese Patent Laid-Open No. 61-5005). In addition, hair cosmetics have been proposed as a conditioner for anti-dandruff which has an excellent feeling of application to hair and an excessive performance, and is excellent in smoothness after drying (see Patent Document 7: Japanese Patent Application Laid-Open No. 2003-176212).

  However, these have insufficient conditioning effects, and the moisturizing of the scalp and hair is not sufficient. Furthermore, including these hair cosmetics, the effects of conventional hair cosmetics containing a moisturizing agent are not continuous, and the hair and the skin are not sticky, and a sufficient feeling of use cannot be obtained. It was. From the above, there has been a demand for a hair cosmetic that has excellent hair conditioning effects and scalp / hair moisturizing properties, has an anti-dandruff effect, and has no stickiness of the background.
