Description

  The present invention relates to a hair cleansing composition, and more particularly to a hair cleansing composition that uses a nonionic surfactant as a surfactant.

  Nonionic surfactants are hypoallergenic and are conventionally used in compositions for cleaning skin and hair. However, since nonionic surfactants are inferior in foaming properties compared to other surfactants, a large amount is not included in cleaning compositions such as shampoos and body cleaning agents that require foaming properties. is the current situation. In addition, when a nonionic surfactant is used as the surfactant, not only the foaming problem but also the squeaky sensation in the skin, hair, etc. is stronger than when other surfactants are used. It also has problems such as being easy.

In order to solve the above squeaky problem, it has been proposed to mix a cationic polymer as a touch-imparting agent with a detergent using a nonionic surfactant (see, for example, Patent Document 1). It has been proposed to mix various silicones as a touch-imparting agent with a detergent using a nonionic surfactant (see, for example, Patent Document 2).
However, when using the above hair cleansing composition, in any case, there is a problem that many of the cationic polymers and various silicones added as a touch-imparting agent are washed away from the hair during hair washing, as a result. However, there is a problem in that sufficient smoothness cannot be imparted to the hair, and therefore, a satisfactory finish cannot be obtained.
