Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a high cleansing power against makeup stains and sebum stains, is hypoallergenic to the skin, has an excellent massage feeling, and is not slippery during rinsing. The present invention relates to a water-based detergent composition which can provide a clean wash and is stable and can be used even in a hot and humid 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. In addition, when a nonionic surfactant is used as a base, it is hypoallergenic and has good detergency, but when it is thickened to make it easier to feel a slimy feel during rinsing There is a problem that the cleaning ability of the agent is significantly reduced.

[0005]

SUMMARY OF THE INVENTION Therefore, an 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 rinsing time. Another object of the present invention is to provide a detergent composition which is expected to be refreshed after being washed and which is stable and can be used even in a hot and humid place.

[0006]

Under such circumstances, the present inventors have conducted diligent research and as a result, have found that a specific nonionic surfactant, polyhydric alcohol or glycol ether,
When used in combination with powder and powder in a specific ratio, it has high cleaning power against oily stains such as make-up and sebum, has low irritation to the skin, is easy to put on hands and face, and has a massage property. Further, they have found that an aqueous detergent composition that is free from slimy feeling during rinsing, has a refreshing feeling, is stable, and can be used even in a hot and humid place is completed, and completed the present invention.

That is, the present invention provides the following component (A),
(B) and (C): (A) General formula (1)
