Synonyms: Aerosil R972; silica dimethyl silylate; silica hydrophobica colloidalis; silicic acid, silylated; silicon dioxide, silanated. CAS No. 68611-44-9. Product ID: PE-0608. Mole weight: 60.08. Category: Anticaking Agents; Emulsion Stabilizer; Glidant; Suspending Agents; Stabilizer; Viscosity-increasing Agents. Product Keywords: Stabilizers; Suspending Agents; PE-0608; Hydrophobic Colloidal Silica; Anticaking Agents; Emulsion Stabilizer; Glidant; Suspending Agents; Stabilizer; Viscosity-increasing Agents; ; 68611-44-9. UNII: NA. Chemical Name: Silane, dichloro-dimethyl-, reaction products with silica. Grade: Pharmceutical Excipients. Administration route: Oral ; rectal. Dosage Form: Oral tablets; rectal suppositories. Stability and Storage Conditions: Hydrophobic colloidal silica should be stored in a well-closed container. It will not absorb moisture but may still absorb volatile substances owing to its high surface area. Source and Preparation: Hydrophobic colloidal silica is prepared by the flame hydrolysis of chlorosilanes, such as silicon tetrachloride, at 1800°C using a hydrogen-oxygen flame. It is rapidly cooled to create an amorphous product and immediately treated with dichlorodimethyl silane in a fluid bed reactor.The resulting surface is covered with dimethylsilyl groups. Ae |  |
