Classification :
Pharmaceutical Excipient Silicon Dioxide
Keywords :
Precipitated Pharmaceutical Silicon Dioxide (Basic Pharma Grade)
PRODUCT DETAILS
Product Description
This basic pharmaceutical-grade silicon dioxide is a widely used excipient for general pharmaceutical manufacturing, produced via a controlled precipitation process. With a minimum SiO₂ purity of 99.5%, it fully meets the fundamental requirements of the Chinese Pharmacopoeia 2025 Edition (ChP 2025), United States Pharmacopeia (USP), and European Pharmacopoeia (EP). Its core functionalities are as a high-performance glidant and anti-caking agent, with exceptional physicochemical stability, no compatibility risks with active pharmaceutical ingredients (APIs) and other excipients, and full compliance with regulatory limits for oral administration for conventional oral solid dosage forms.

Core Applications
This grade delivers reliable glidant and anti-caking performance for conventional oral solid dosage forms, including tablets, capsules, and granules. It effectively addresses common manufacturing challenges such as powder caking and poor flowability during compression and encapsulation. It exhibits excellent compatibility with a wide range of APIs and pharmaceutical excipients, with no adverse impact on the efficacy, stability, or quality of the final drug product.
Manufacturing Advantages
We operate a dedicated 10,000-ton annual capacity production line for pharmaceutical silicon dioxide, fully compliant with pharmaceutical Good Manufacturing Practices (GMP). Every batch undergoes full in-process quality testing for critical pharmacopoeia parameters to ensure consistent product quality. With stable production capacity and a standard lead time of 7–10 days, we reliably fulfill bulk and regular procurement needs for pharmaceutical manufacturers, with an excellent cost-performance ratio.
