In recent years, with changes in lifestyle habits, there is a need to clean the head and body with a shower or the like in a short time in the morning and to easily clean the hair and body with a single cleaning agent.
In response to such needs, cleaning agents based on higher fatty acid salts provide a refreshing feel to the body during rinsing, but the hair is squeezed and poorly fingered. On the other hand, alkyl ether sulfates are mainly used. In the case of the rinse agent, the finger does not smooth the hair when rinsing, but when you rinse your body, it will remain slim and you will not get a refreshing feel.
In addition, in the case of detergents that combine higher fatty acid salts and alkyl ether sulfates, the body is refreshed when rinsing, but it will squeeze against the hair, or the hair will not be damaged, but the body will become wet, etc. Only one of the performances could be satisfied.
