Abstract:
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.
