Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a high detergency against makeup stains and sebum stains, is hypoallergenic to the skin, has an excellent massage feeling and rinseability, and is stable, hot and humid. The present invention relates to a water-based gel-like detergent composition that can be used at any place.

[0002]

2. Description of the Related Art Makeup cosmetics such as lipsticks, foundations, eye shadows, mascaras, etc.
Since it contains a solid oil, solubilization and emulsification are insufficient with the use of a solid or pasty face wash which is mainly composed of ordinary soap, and it is difficult to remove makeup stains. Conventionally, in order to remove such makeup stains, gel-like cleansing agents, cleansing creams, cleansing oils and the like, which mainly contain an oily base, have been used.

However, with these cleansing agents based on oily bases, the cleansing of sebum stains such as solid stains clogging pores is insufficient, and the oily feeling remains, so that cleansing agents are used. After washing, it was necessary to wash again with a paste-like face wash. Also,
When a cleansing agent mainly composed of an oily base is used in a hot and humid place, it contains water, resulting in poor stability, separation and deterioration of detergency. Further, a cleansing oil or the like having a low viscosity has a drawback that it flows from the face when washing the face and stains clothes and the like.

Further, a detergent composition for removing oily stains such as make-up and sebum is also required to be mild to the skin. However, if a standard fatty acid soap or anionic surfactant is used as a base, it generally causes high irritation to the skin. Further, when a nonionic surfactant is used as a base, it is hypoallergenic and has good detergency, but if the viscosity is increased to facilitate massage, the detergency of the surfactant will be significantly reduced. There was a problem.

[0005]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to have high detergency against makeup stains and sebum stains, low irritation to the skin, excellent massage properties, and stable. Another object of the present invention is to provide a cleaning composition that can be used even in hot and humid places.
