Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shampoo composition that has good foaming and slippery foam quality at the time of shampooing, has a smooth feel at the time of rinsing, and gives gloss to the finished hair.
[0002]
[Prior art]
In hair treatment agents such as hair rinses and hair conditioners, the pH of the system is also lowered for the purpose of imparting gloss and flexibility to the hair. However, since the hair cleansing agent is not usually intended to give gloss or flexibility, no attempt has been made to lower the pH of the hair cleansing agent.
[0003]
[Problems to be solved by the invention]
The present inventors have studied a low pH hair cleaning agent using an organic acid in order to give the hair cleaning agent the function of imparting the above gloss, flexibility and cohesiveness. However, in the low pH region, there is a problem that the state of the detergent system changes, and a sufficient amount of foam and foam quality cannot be obtained during hair washing.
