Colloidal Silicon Dioxide
Zhongqi (Shandong) Silicon Materials Co., Ltd. specializes in manufacturing high-quality colloidal silicon dioxide, also known as fumed silica, which is the most widely used pharmaceutical excipient globally per Google Trends data.
Premium Colloidal Silica for Advanced Pharmaceutical Formulations
Zhongqi (Shandong) Silicon Materials Co., Ltd. specializes in manufacturing high-quality colloidal silicon dioxide, also known as fumed silica, which is the most widely used pharmaceutical excipient globally per Google Trends data. Our ZLXIDE™ series colloidal silica is produced through advanced vapor-phase hydrolysis technology.
Production Technology:
Our colloidal silicon dioxide is manufactured by the high-temperature hydrolysis of silicon compounds in a hydrogen-oxygen flame. This process yields ultra-fine, non-porous amorphous silica particles with primary particle sizes ranging from 7 to 40 nanometers, forming a unique three-dimensional network structure.
ZLXIDE™ Series Product Grades:
- ZLXIDE™ 200: Standard grade with specific surface area of 200 m²/g
- ZLXIDE™ 300: High surface area grade for enhanced adsorption
- ZLXIDE™ 380: Ultra-high surface area grade for specialized applications
- ZLXIDE™ R972: Hydrophobic modified grade for specific formulation needs
Superior Performance:
- Exceptional flow improvement properties
- Excellent anti-caking and anti-adhesion properties
- Superior thickening and thixotropic characteristics
- Outstanding suspension stabilization
- Negligible impact on drug bioavailability
Regulatory Compliance:
Our colloidal silicon dioxide meets the requirements of major pharmacopoeias worldwide, including USP, EP, BP, and CP. It is suitable for use in all types of pharmaceutical formulations, including oral, topical, and parenteral preparations.
