112945-52-5 Silica, fumed
upac Name:dioxosilane
CAS No.: 112945-52-5
Molecular Weight:60.0843
Introduction: Synthetic Amorphous Silica has interesting thickening and thixotropic properties, and an enormous external surface area. It is produced by a vapor phase hydrolysis process using chlorosilanes or substituted silanes such as, silicon tetrachloride in a flame of hydrogen and oxygen. This material is formed and collected in a dry state. This product contains no detectable crystalline silica.

PRODUCT DESCRIPTION


Amorphous silica can be used as an excipient, such as viscosifier, suspending agent, tablet disintegrating agent, adsorbent dispersing agent as liquid in powders. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs
