Silicon Dioxide is widely used in pharmaceutical formulations, cosmetics, and food products. It is also widely used in orally-dosed nutritional products and regarded as an essentially nontoxic, nonirritant excipient. Silicon dioxide readily absorbs large quantities of water from its surroundings, and does this without itself liquefying. Silica is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to adsorb water in hygroscopic applications. It is the primary component of diatomaceous earth. Colloidal silica is also used as a wine, beer, and juice fining agent.
In the pharmaceutical industry, silicon dioxide (also known as colloidal silicon dioxide) has many uses in tablet-making: some include as an anti-caking agent, adsorbent, disintegrant, or glidant to allow powder to flow freely when tablets are processed.
The major application of silica in solid-dosage forms is as a glidant and anti-static agent to improve the flow properties of granulations in high-speed tablet and capsule machines. Particulate flow has a direct effect on weight uniformity and plays an important role in solid-solid blending and powder homogeneity.
