Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excellent detergent composition which has sufficient foamability and detergency, but has sufficient foaming during use and a moist feeling after use.

[0002]

2. Description of the Related Art A conventional detergent composition containing a higher fatty acid soap as a main component and an anionic surfactant is excellent in a refreshing feeling at the time of use, good rinsing and good defoaming. However, it has a drawback that it is inferior in foaming, sustainability of foam, and moist feeling after use. With regard to foam persistence, it was improved in JP-A-59-128174 by blending a cationic polymer. However, no detergent composition having foaming and a moist feeling after use has been obtained. The present invention is
It is a technical object to provide a detergent composition which is excellent in a refreshing feeling at the time of use, good rinsing ability, good defoaming ability, and long-lasting foaminess, and has sufficient foaming and moisturizing feeling after use.
