Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal cleansing composition which is excellent in foaming property and imparts a good feeling on skin and hair and a sufficient conditioning effect to the skin and hair.

[0002]

2. Description of the Related Art Hair cleaning compositions containing various surfactants contain various conditioning ingredients in order to suppress creaking of the hair during rinsing and dryness of the hair after drying. When the components are used in combination, the foaming performance such as foaming power, foam quality and foam stability may be deteriorated.

On the other hand, in cleaning agents other than hair, a conditioning component such as an oil agent may be blended for the purpose of improving the feeling of use on the skin. In this case as well, the foaming power, the foam quality, etc. are the same as above. There was a problem that it decreased.
