The conventional detergent composition has a problem that the detergency is insufficient, and the skin remains oily after the wiping or after rinsing.

The present invention relates to a makeup which is difficult to remove even if it is waterproof mascara or the like A detergent composition that removes the rough sensation during washing and which is quickly dried after washing, thereby providing a refreshing and smooth skin feel.

The so-called "roughness in washing" means that when the hand is used to remove the detergent and is applied to the face and massaged, it is felt that the finger is blocked and stops on the face. In addition, the phrase "dry and dry quickly after washing" means that the skin cleansing agent is taken in an appropriate amount of the cotton pad, and the drying speed after wiping the face is washed.
