PRODUCT DETAILS
1. Product Description
Pharmaceutical Grade Silicon Dioxide is a universal-grade pharmaceutical excipient manufactured via a refined precipitation process, fully compliant with the general standards of the Chinese Pharmacopoeia (ChP), United States Pharmacopeia (USP), and European Pharmacopoeia (EP). Boasting ultra-high purity, odorless and tasteless properties, with heavy metal and microbial residues strictly controlled within pharmacopoeia limits, this product delivers two core functional benefits: superior glidant and anti-caking performance. With exceptional physicochemical stability and low dosage requirements, it is ideally suited for the production of a wide range of solid pharmaceutical dosage forms, balancing uncompromising regulatory compliance with reliable practical performance to meet the fundamental procurement needs of pharmaceutical manufacturers worldwide.
