Silica-core silicone-shell particles, emulsion containing the same dispersed therein, and process for producing the emulsion

摘要: Colloidal silica-core silicone-shell particles, an emulsion containing, as a solid component, at least 30% by weight of the and process for producing emulsion. A colloidal particles comprising (A) from 99.9% to 5% cores which are silica (B) 0.1% 95% shells organosiloxy group represented formula ##EQU1## wherein R 1 may be same or different each represents substituted unsubstituted monovalent hydrocarbon having 8 carbon atoms, Q hydrogen atom alkyl 6 p is integer 3, q 9 2, with proviso that (p+q) polyorganosiloxane average composition ##EQU2## 2 atoms number 0.8 3.0.
