2. Description of the Related Art Conventionally, oily cosmetics have been mainly composed of solid oil, semi-solid oil, liquid oil, and colorant. In order to obtain a comfortable usability and a feeling of use as a cosmetic, Blending studies of oils and colorants having various shapes and properties have been conducted. In particular, as a method for improving the durability of oily cosmetics, an organic silicone resin and volatile silicone oil as shown in JP-A-61-65809 are used, and residual components are colored by volatilization of the volatile silicone oil after coating. There were some that consisted only of agents and resin components.

[0003]

However, although the one using the organic silicone resin and the volatile silicone oil as described above has an excellent function of preventing makeup loss, it does not sufficiently moisturize the use site after the volatile components have evaporated. However, it was not satisfactory in terms of usability and feeling such that the cosmetic film had no gloss. As a method of producing a moisturizing feeling after use, it is possible to mix a liquid oil agent having a high emollient property, but there is a problem that it is not possible to mix a large amount of the liquid oil agent, because it causes a decrease in the function of preventing makeup loss. It was
