In pharmaceutical formulation, excipients are as critical as active pharmaceutical ingredients (APIs). Silicon Dioxide (CAS 7631-86-9) is a widely used excipient valued for its unique properties that enhance drug product manufacturing and stability. As a specialized manufacturer and supplier of pharmaceutical intermediates and fine chemicals in China, NINGBO INNO PHARMCHEM CO.,LTD. understands the stringent demands of the pharmaceutical industry.
Silicon Dioxide, particularly in its colloidal or fumed forms, serves several vital functions in tablet and capsule manufacturing. It acts as a glidant, improving the flowability of powder blends to ensure uniform filling of tablet dies and capsule shells. It also functions as an anti-caking agent, preventing powder agglomeration and maintaining consistent product consistency. Furthermore, its adsorbent properties can be leveraged to stabilize moisture-sensitive APIs.
