2. Description of the Related Art Conventionally, for removing makeup cosmetics, a cleansing cream obtained by emulsifying an oily component with a surfactant, an oily cleansing cream mainly containing an oily component, and the like have been used. Recently, gel-like or highly viscous liquid make-up removers have come to occupy a large share due to their fresh feeling and ease of use after washing. As such a makeup removing agent, an aqueous gel, an oily gel and an oil gel in which a surfactant is dispersed and which is thickened with a thickener polymer are known. The water-based gel may contain a small amount of oily ingredients, but these can be washed off with water and are characterized by a refreshing feeling of use. There are emulsified type and liquid crystalline type oily gels, which are well compatible with makeup cosmetics, and O / W type emulsified ones and liquid crystal type ones can be washed off with water. Oil gel is very familiar with make-up cosmetics and is characterized by a great cleaning power.

However, the effect of removing the makeup cosmetics is not sufficient with the aqueous gel, and if the amount of the surfactant is increased in order to enhance the removing effect, skin irritation may be observed, and dryness and rough skin may be observed after use. May occur. On the other hand, oil gels and W / O emulsion type oily gels cannot be washed away with water because the oil phase is a continuous phase, and after use, it was necessary to wipe them off with a tissue paper or the like and then rewash with a face wash or the like. . O / W
Emulsified and liquid crystal type oily gels can be washed off with water, but oily ingredients often remain on the skin, and a sticky feeling remains after washing with water, and a refreshing feeling is not obtained. It was
