Organopolysiloxane and powder treatment agent, preparation for external use and cosmetic comprising the same

Abstract

The present invention provides a novel organopolysiloxane in which a rich hydrophilic property is exhibited, not only superior miscibility with a hydrophilic component and but also a hydrophobic property are exhibited, and superior miscibility with both a silicone oil and a non-silicone oil such as a hydrocarbon oil, an ester oil or the like, and provide various usages of the aforementioned novel organopolysiloxane by developing the superior characteristics thereof such as good surface activity power, a distinctive sensation during use, increased stability and the like. A co-modified organopolysiloxane having a specified chemical structure in which a sugar alcohol-modified group and a long-chain hydrocarbon group are present in one molecule is produced. The co-modified organopolysiloxane is blended, as a surfactant, a powder treatment agent, a gelling agent or the like, or as a cosmetic raw material appropriately together with powder(s), oil agent(s) or the like, in a preparation for external use, and in particular, a cosmetic.
