摘要:
Dispersions of an encapsulated material by a polymeric membrane in a medium are disclosed. Such dispersions are useful in topical compositions including cosmetics and sunscreens.
摘要:
A silicone emulsion free of a surfactant and an emulsifier is disclosed. The emulsion includes a dispersed oil phase having a polyorganosiloxane with one or more hydroxyl groups in a continuous aqueous or anhydrous organic diol phase including an anionic polymer.

A composition is described herein that includes a fluorosilicone, a silicon-based crosslinker, a reinforcement filler, a curing catalyst, a first non-reactive spacer filler, and a second filler comprising one or more silanol groups. Methods of using such a composition are also described.
摘要:
Compositions for forming a silicone elastomer and the silicone elastomers thereby which have improved characteristics and which can be used for medical devices are disclosed. The composition for forming a silicone elastomer can include (A) an organopolysiloxane having silicon-bonded alkenyl groups; (B) an organohydrogensiloxane having an average of two or more silicon-bonded hydrogen atoms in the molecule; (C) an inorganic filler; and (D) a filler treatment agent which includes an alkenyl-containing group, e.g., an alkenyl-containing organosilane or organosilazane.
