<p><P>PROBLEM TO BE SOLVED: To provide a novel organopolysiloxane which is volatile, has low-temperature stability, brings about excellent gloss, and has a property excellent in compatibility with an ultraviolet absorber, a process for producing the same, and a cosmetic containing the organopolysiloxane. <P>SOLUTION: The organopolysiloxane is, for example, 1, 2-bis(pentamethyldisiloxy)ethane of the formula produced by hydrolyzing 1, 2-bis(chlorodimethylsilyl)ethane or cyclic 1, 1, 3, 3, 6, 6, 8, 8-octamethyl-2, 7-dioxy-1, 3, 6, 8-tetrasilacyclodecane. The organosiloxane is used as a substitute for the conventional octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane or methyltrimethicone and the cosmetic containing the organopolysiloxane is excellent in the touch in use, brings about excellent external appearance, and can be highly flexibly compounded with various components such as an ultraviolet absorber. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
