A novel saccharide siloxane copolymer has improved stability in the presence of water as compared to certain previously known saccharide siloxanes. The saccharide siloxane copolymer is useful in personal care compositions.

摘要:
The viscosity of a solvent is modified by thickening the solvent with a silicone latex. A silicone latex having a plurality of crosslinked polysiloxane particles is first prepared by mixing the siloxane polymer, a surfactant, and water; emulsifying the mixture to a gel phase; diluting the emulsion with water; adding a cure package (i.e., a catalyst, a crosslinker, or both, or a self catalytic crosslinker); and then without removing the water from the latex and after the particles of siloxane polymer in the latex have been cured, mixing the latex and solvent to thicken the solvent, forming viscous liquids, gels, and pastes. Water in the latex thickened solvent composition can be stabilized by adding a silicone polyether during mixing of the latex and the solvent. These stabilized latex thickened solvent compositions have beneficial properties such as clarity, shelf stability, and ease of preparation; and therefore have wide areas of application, especially as additives in antiperspirants, deodorants, and other personal care applications.
摘要:
Organosiloxane compositions that cure in the presence of ultraviolet radiation comprise a alkenyl-substituted fluorinated polyorganosiloxane, a mercaptoalkyl-substituted fluorinated polyorganosiloxane and a photoinitiator. The cured compositions are particularly useful as coating and encapsulants to protect electronic devices that are exposed to hydrocarbon fuels.
