Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention has excellent cleaning power for makeup cosmetics and sebum stains, is hypoallergenic to the skin, and has excellent massage feel and rinsability.
In addition, the present invention relates to an aqueous cleaning composition having high stability and which can be suitably used even in a high temperature and high humidity place.

[0002]

2. Description of the Related Art Make-up cosmetics such as lipstick, foundation, eyeshadow, mascara, etc., require a large amount of oil,
Since solid fat is contained, solubilization and emulsification are insufficient if a solid or paste-like face wash mainly containing ordinary soap is used, and it is difficult to remove makeup stains. Conventionally, in order to remove such makeup stains, gel cleansing agents, cleansing creams, cleansing oils, and the like mainly containing an oil base have been used.

However, with these cleansing agents based on oily bases, the cleaning of sebum stains such as solid stains clogging pores is insufficient, and
Since an oily feeling remains, it was necessary to wash again with a paste-like face wash after washing with a cleansing agent. Further, when used in a hot and humid place, a cleansing agent mainly composed of an oily base has a problem that stability becomes poor due to the inclusion of water, and separation and detergency deteriorate. Furthermore, there is a problem that cleansing oil or the like having a low viscosity flows from the face when washing the face and stains clothes and the like.

Further, a detergent composition for removing make-up cosmetics and oily stains such as sebum is also required to be hypoallergenic to the skin. However, ordinary fatty acid soaps and other detergent compositions based on anionic surfactants are generally highly irritating to the skin, and detergent compositions based on nonionic surfactants are also used. The product has low irritation and good detergency, but when it is thickened to maintain shape retention and to be easy to use without liquid dripping etc., the washing speed decreases and the sliminess during rinsing increases. There was a problem.

[0005]
