And a method for producing the same.

The oil-based solid cleansing material is widely used because it has excellent handling properties as compared with the liquid cleansing material, such that it does not spill from between fingers and does not easily adhere to other things. Conventionally, in order to make the cleansing oil into an oily solid, a solid oil such as an oligoester oil gelling agent or a hydrocarbon oil having a melting point of 60 to 120 ° C. has been used. (See, for example, Patent Documents 1 and 2)
However, in these conventional techniques, the spreadability on the skin or the like is not sufficient or the weight may be sensuously sensed, and the surfactant or liquid oil used in combination may cause a solid oil-based cleansing agent. There was a problem that control of moldability and stability was sometimes difficult.
Therefore, there is a need for an oily solid cleansing material that has good spreadability on the skin and lips at the time of application, has sufficient function as a cleansing agent, has a good feeling of use after application, and is stable while being an oily solid. .
