Description

  The present invention relates to a hair cleanser.

  Conventionally, various types of interfaces have been included in hair cleansing agents for the purpose of imparting effects such as good usability to hair and conditioning properties in addition to the basic performance of hair cleansing properties, or for the purpose of stably blending oily components and the like.

  On the other hand, in hot and humid areas such as Taiwan and Southeast Asia, the amount of sebum is increased because it is easy to sweat, and the skin is sticky and the hair is easily soiled. In particular, a woman with long hair has a problem that the hair tends to stick to the skin.

  However, none of the conventional hair cleansing agents can be fully satisfied with the effect of making it difficult for the hair after washing to stick to the skin. Therefore, the present invention relates to a hair cleanser that can maintain the difficulty of sticking to the skin without stickiness of the hair after washing even under conditions of high temperature and humidity and high sweating and sebum secretion.

  The present inventors have combined the polyoxyethylene alkyl ether acetates and polyoxyethylene alkyl ether sulfates each having an ethylene oxide average addition mole number within a specific range, and a tertiary amine type cationic surfactant. It has been found that a hair cleanser that satisfies the requirements can be obtained.

(Sebum detergency)
On a polyethylene film, about 100 mg of artificial sebum having the following composition was applied and spread over a range of about 2 cm square. Each shampoo composition was diluted 5 mass times with water, the film was immersed in this diluted aqueous solution, heated to 40 ° C., and allowed to stand for 5 minutes. After that, it was washed by rubbing for 10 seconds while applying a light force (100 g weight) with a finger, and the sebum that floated in the aqueous solution was rinsed with running water, and then the film was dried and the amount of remaining sebum was measured. Tables 1 and 2 show the amount of sebum removed by washing from the difference between the amount of sebum applied and the amount of remaining sebum, and the ratio of the amount of sebum removed to the amount of applied sebum was taken as the cleaning rate.
