Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition which provides moisturizing moisture and a smooth sliding feeling without bulking or sticking the skin after use.

[0002]

2. Description of the Related Art Generally, a large amount of various surfactants are incorporated in a skin cleansing composition as a cleansing base. This also removes sebum that protects the skin surface, causing problems such as bulkiness, firmness, and rough skin. In order to alleviate this to some extent, a moisturizing agent is blended in a usual cleaning agent. However, since the humectant is hydrophilic in its function, there is a serious disadvantage that most of the humectant flows out when the detergent composition is rinsed. When combined, it can impair the cleaning effect,
There have been problems such as difficulty in securing the storage stability of the product and stickiness. On the other hand, when a hydrophobic substance such as petrolatum, which has a moisturizing effect if separately applied as a protective agent after washing / drying the skin, is added to the detergent composition and used, it is formed into micelles by the surfactant and hardly remains. , Could not fulfill its function.

[0003] The object of the present invention is to provide a substance which is safe and non-irritating to the human body, remains on the skin with high efficiency even after washing / rinsing, and gives a non-greasy, moisturized and smooth slipping feeling. Containing, has a very good feel and moisturizing /
An object of the present invention is to provide a cleaning composition having an excellent protective effect.
