摘要

The present invention relates to a novel organopolysiloxane having a specified structure and a cosmetic containing the aforementioned organopolysiloxane. The novel organopolysiloxane according to the present invention is volatile, possesses stability at low temperature, provides superior glossiness, and has a superior property with respect to miscibility with a UV- ray absorber, and which is useful as a replacement of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, or methyltrimethicone. The cosmetic according to the present invention can provide superior feeling to the touch during use and a superior outer appearance. Furthermore, a degree of freedom in blending various components such as UV-ray absorbers into the cosmetic according to the present invention is increased.
