Description

The present invention relates to a cleansing composition.

Oily liquid cleansing compositions are on the market for the purpose of removing skin stains and oily make-up cosmetics. Oil-based liquid cleansing compositions are superior in cleansing effect to emulsified cream-type, emulsion-type cleansing compositions, or aqueous liquid/gel-type cleansing compositions. However, since oil cleansing agents are composed of oily ingredients, their viscosity depends on the oil agents they contain, and when they are picked up on the hands or applied to the skin, they tend to drip off, resulting in poor usability during cleansing. was there.

Therefore, for the purpose of increasing the viscosity of the oil cleansing agent and improving its usability, for example, as shown in Patent Document 1, an oily cleansing agent using a self-organizing body formed by a monoalkyl phosphate ester and a specific neutralizing agent is used. A gel composition (Patent Document 1) and the like have been proposed.

WO2017/209182

However, the oily gel composition as disclosed in Patent Document 1 above has a problem of inferior cleansing power.
Accordingly, the present invention has been made in view of such circumstances, and an object of the present invention is to provide a cleansing agent that has a melting feeling in use and excellent cleansing power.
