Colloidal silicon dioxide is a very fine amorphous silica used in low concentrations as a glidant, anti-caking agent, and adsorbent.
In tablets and capsules, it improves powder flow, reduces sticking, and enhances die filling and weight uniformity.
It can adsorb small quantities of liquids, flavors, or oily actives, enabling conversion into free-flowing powders.
It is also used in food, cosmetics, and industrial formulations to prevent caking and stabilize dispersions.
Pharmacopeial grades are characterized by high purity, controlled particle size, and low heavy metal content.
