Bulk Pharmaceutical Grade Silicon Dioxide
Classification :
Pharmaceutical Excipient Silicon Dioxide
Keywords :
Bulk Pharmaceutical Grade Silicon Dioxide
PRODUCT DETAILS
1. Product Description
Bulk pharmaceutical grade silicon dioxide is custom-developed for large-volume procurement scenarios, fully compliant with the Chinese Pharmacopoeia (ChP), United States Pharmacopeia (USP), and European Pharmacopoeia (EP) – the world’s leading pharmacopoeial standards. Produced via large-scale precision refining techniques, it features uniform and fine powder with stable flowability, free from caking and impurities. Heavy metals and microbial residues are strictly controlled within pharmacopoeial limits, and it delivers three core functions: glidancy, anti-caking, and dispersion. Boasting stable physicochemical properties and high cost-effectiveness for bulk orders, it supports long-term stable supply and is tailored to the large-scale raw material procurement needs of overseas major pharmaceutical manufacturers and medical traders.

3. Applications
It is core-adapted to the large-scale production and resale needs of overseas major pharmaceutical manufacturers and medical traders. It can be used in mass production of various solid dosage forms including tablets, capsules, granules, and pharmaceutical powders as a key glidant and anti-caking agent. It effectively reduces inter-powder friction, eliminates punch sticking, wall adhesion and caking during storage in bulk production, and optimizes the precision of filling and tableting. It has no interaction with active pharmaceutical ingredients and does not affect the disintegration and dissolution of dosage forms. Bulk procurement can significantly reduce raw material costs.
4. Factory Advantages
Our enterprise owns a 10,000-ton scale production line for pharmaceutical-grade silicon dioxide, certified by Pharmaceutical GMP and ISO9001. Equipped with pharmacopoeial standard bulk testing equipment, we conduct strict control over the particle size, dispersibility and purity of bulk products with minimal batch-to-batch variation and stable production capacity. With years of experience in bulk overseas supply, we export to more than 30 countries and regions, and have established long-term bulk cooperation with many global major pharmaceutical manufacturers and traders. Flexible delivery cycles can be negotiated, with obvious price advantages for bulk procurement, and quality traceability services are provided after-sales.
5. Shipping & Packaging
- Standard Packaging: 20/25kg pharmaceutical-grade paper-plastic composite bags with moisture-proof PE inner liners. The thickened design is suitable for large-volume warehousing and transportation to prevent powder moisture absorption and caking.
- Storage & Transportation Requirements: Sealed storage in a cool, dry and well-ventilated place. Non-hazardous chemicals, supporting bulk sea/air transportation worldwide, compliant with international bulk storage and transportation standards for pharmaceutical raw materials, and port pick-up is available.
- Labeling Norms: Customizable multilingual labels (English/French/German) marked with product name, bulk specifications, applicable pharmacopoeial standards, batch number and validity period, with custom bulk shipping marks available.
6. Frequently Asked Questions
Q: Can I get a price discount for bulk procurement, and what is the discount level?
A: Exclusive bulk discounts are available, with higher discounts for larger purchase volumes. A basic discount is offered for orders starting from 1000kg, and more competitive prices can be negotiated for long-term bulk cooperation.
Q: Can product quality consistency be guaranteed for bulk supply, and how to handle quality problems if they occur?
A: Yes. Every batch of bulk products undergoes a full set of pharmacopoeial tests with an attached bulk test report. In case of quality problems, unconditional return and exchange are available, and the relevant logistics costs will be borne by us.
