2. Description of the Related Art Conventionally, in cosmetics, a film-forming agent has been blended in order to improve the water resistance and oil resistance and to improve the durability of the cosmetic effect (Japanese Unexamined Patent Application Publication No. Hei.
-25411, JP-A-6-279253, JP-A-7-279
187951).

[0003]

However, if the compounding amount of the film-forming agent is increased in order to enhance the persistence of the cosmetic effect, stickiness and spread during use become worse,
There were problems such as poor compatibility with the oil agent and difficulty in stably compounding. Further, when a film-forming agent having a strong film-forming ability is used, a feeling of tightness or a feeling of pressure may be generated. Therefore, it has been desired to develop a cosmetic which has good water resistance and oil resistance, has excellent persistence of the cosmetic effect, and has a good feeling of use such as non-stickiness, light spread, and no oiliness.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, the cosmetic contains a specific organopolysiloxane and an acryl-silicone-based graft copolymer. By doing, while having good usability such as light stretch, stickiness, lack of oiliness, high emollient effect, water resistance, oil resistance,
The inventors have found that the present invention has excellent makeup persistence, and have completed the present invention.

That is, the present invention relates to the following components (A) and (B): (A) an organopolysiloxane represented by the following general formula (1):
