DISCLOSURE OF INVENTION

Problems to be solved by the invention

However, cosmetics made by gelling oil-based components with bentonite, oil gelling agents or solid oils to give viscosity to the system have excellent usability, but have a white cloud caused by the gelling agent itself. In some cases, such as stickiness after use caused by a solid oil or the like could not be satisfied.

In addition, the scrubbing action that increases the cleansing agent to the skin and fuses it with the makeup material has the effect of promoting blood circulation and softening or brightening the skin similarly to massage. These effects are expected to increase if there is moderate resistance on the skin. However, the cleansing agent obtained by gelling an oil-based component with bentonite, an oily gelling agent or a solid oil to give the system a viscosity, significantly lowered the viscosity of the system due to the painting behavior during use, and thus a sufficient massage effect could not be obtained.

On the other hand, among the oil-based solid cosmetics having a transparent appearance, the polyamide resin is blended with oil and is easily leaked out due to changes in time and temperature. In addition, the blend of 12-hydroxystearic acid was excellent in the transparency of appearance, but somewhat inferior in temperature stability, and the blend of dextrin fatty acid ester was not satisfactory in both transparency and solidification of the system. Moreover, the technique regarding these transparency is a technique which assumed transparent lipstick, and it was not the degree which the usability was able to tolerate, for example, it is difficult to spread long and sticky to apply it as a cleansing agent.

That is, in the present state, an oil-based cleansing agent having a transparent or translucent appearance, excellent in feeling, no drop in viscosity due to the painting action at the time of use, and excellent massage effect is not on the market.

Means for solving the problem

It confirmed and completed this invention.

In addition, the act of painting by the oil-based cleansing agent can not only massage effect such as promoting blood circulation, but also enhances the cleansing effect of infiltrating the cleansing agent to the inside of the skin to melt the cleansing components and make the cleansing components float above the skin. Confirmed at the same time.

That is, this invention provides the oil-based cleansing agent containing the following components (A)-(C) and are semi-solid to solid form:

(A) Polyamide modified silicone which has a repeating unit represented by following General formula (1):
