Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cleaning agent, and more particularly to a cleaning agent suitable as a hair cleaning agent.

[0002]

2. Description of the Related Art Cleansing agents such as shampoos and body shampoos are cosmetics used for removing biological metabolites such as dirt and sebum attached to the human body such as skin and hair. The washing action is very important in the sense that such a dirt or a metabolite of the living body prevents the living body from emitting a bad smell or generating a peroxide harmful to the living body. The most problematic in such a washing action is that when the components to be washed are removed by washing, even components that keep the body moist are washed away, and smoothness and moist feeling are lost. That is the tendency. Such a phenomenon has a particularly serious effect in the case of hair. That is, such a loss of moist feeling and smoothness of the hair often hinders combing in a subsequent combing action and causes damage to the hair. For this reason, in washing hair, it is common practice to perform post-treatment with a post-treatment cleaning agent such as a rinse to improve the physical properties of the hair. For this reason, everyone has already experienced that the washing time of hair is increased due to this post-treatment step. However, in recent years, such operations are disliked due to the busyness, and a so-called “rinse-in shampoo” containing a substance having an affinity for hair and capable of eliminating a post-treatment step has been developed and gained popularity. However, at present, such preparations cannot be said to have sufficient detergency and post-treatment properties. That is, there has been a demand for the development of a rinse-in shampoo having the same effect as that after the post-treatment step even if the post-treatment step is omitted.
