摘要： The present invention provides an organohydrogenpolysiloxane which does not have an average chemical structure as encountered with organopolysiloxanes prepared by equilibration polymerization reactions, but rather which has a clear, defined chemical structure in which the position and number of silicon-bonded hydrogen groups is clearly defined. The organopolysiloxane has a branched structure in the vicinity of one terminal of the molecular chain and has the silicon-bonded hydrogen group at each of the resulting derivative terminals. The organopolysiloxanes can be addition-reacted with, for example, organic compounds having various functional groups to give organopolysiloxane having two organofunctional groups clustered at one terminal.

摘要： The present invention provides a novel modified-polysiloxane, method for producing the same, and a cosmetic containing the same. The aforementioned modified-polysiloxane exhibits a reduced viscosity and superior operationability as compared with conventional polyoxyalkylene-modified polysiloxanes and polyglycerol-modified polysiloxanes. In addition, since the modified-polysiloxane is hardly oxidized in air, hardly produce allergenic compounds such as formates, and aldehydes such as formaldehyde, during storage over time, an increased environmental compatibility can be exhibited. In addition, the modified-polysiloxane of the present invention exhibits a reduced hydrolysis property and is stable. In the modified-polysiloxane of the present invention, the terminal hydroxyl groups of a polyglycerol-modified polysiloxane are partially blocked with hydrocarbon groups.
