Synonyms: Aerosil; Cab-O-Sil; Cab-O-Sil M-5P; colloidal silica; fumed silica; fumed silicon dioxide; hochdisperses silicum dioxid; SAS; silica colloidalis anhydrica; silica sol; silicic anhydride; silicon dioxide colloidal; silicon dioxide fumed; synthetic amorphous silica; Wacker HDK. CAS No. 7631-86-9. Product ID: PE0383. Molecular formula: SiO2. Mole weight: 60.08. Category: Adsorbents; Stabilizers; Disintegrants. Product Keywords: Pharmaceutical Excipients; Excipients for Solid Dosage Form; Filler Excipients; Absorbent; Colloidal Silicon Dioxide; PE0383; ETJ7Z6XBU4; 7631-86-9; 7631-86-9. UNII: ETJ7Z6XBU4. Chemical Name: Silica. Administration route: Oral; Buccal; Dental; Sublingual; Transdermal; Rectal; Vaginal. Stability and Storage Conditions: Colloidal silicon dioxide is hygroscopic but adsorbs large quantities of water without liquefying. Applications: Colloidal silicon dioxide is widely used in pharmaceuticals,cosmetics, and food products. Its small particle size and large specific surface area give it desirable flow characteristics that are exploited to improve the flow properties of dry powders in a number of processes such as tableting and capsule filling. Colloidal silicon dioxide is also used to stabilize emulsions a

Source and Preparation: Colloidal silica is prepared by the vapor hydrolysis of chlorosilane, such as silicon tetrachloride, at 1800°C with hydrogen, oxygen flame combustion preparation. Applications: This product is widely used in pharmaceutical, cosmetic and food products. The small particle size and large specific surface area give it the desired fluidity, which can be used to improve the fluidity of dry powder in many processes, such as sheet pressing. It can also be used to stabilize emulsions, as thixotropic thickening agent and suspension aid in gels and semi-solid
Decamethylcyclopentasiloxane
Decamethylcyclopentasiloxane (D5) is an organosilicon compound with the formula [(CH3)2SiO]5. It is a colorless and odorless liquid that is slightly volatile. The compound is classified as a cyclomethicone. Such fluids are commonly used in cosmetics, such as deodorants, sunblocks, hair sprays and skin care products. It is becoming more common in hair conditioners, as it makes the hair easier to brush without breakage. It is also used as part of silicone based personal lubricants. D5 is considered an emollient. In Canada, among the volume used in consumer products approximately 70% were for antiperspirants and 20% for hair care products. Uses: It widely used in cosmetics and body care products, such as skin care, sunscreen,makeup, hair conditioning products, good compatibility with most of the alcohol and other cosmetic solvents. be directly used as the carrier, the main raw material, also can be used as an additive; and be used in aqueous systems by the method of emulsification. Group: Salt. Alternative Names: Cyclopentasiloxane, decamethyl-; DecaMethylcyclopentasiloxane; 2,2,4,4,6,6,8,8,10,10-decamethyl-1,3,5,7,9,2,4,6,8,10-pentaoxapentasilecane; D5 Cyclomethicone. CAS No. 541-02-6. Pack Sizes: 10 g; 100 g. Product ID: Decamethylcyclopentasiloxane. Molecular formula: 370.77 g/mol. Mole weight: C10H30O5Si5. ≥99%.
Hydrophobic Colloidal Silica
Hydrophobic colloidal silica occurs as a light, fine, white or almost white amorphous powder, not wettable by water. 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
