Quality Control

Our Magnesiumsilicate is produced under a strict quality management system. Each batch is tested to ensure it meets relevant specifications for its intended application, which may include compliance with FCC (Food Chemicals Codex) for food-grade uses or in-house pharmaceutical standards. Comprehensive testing covers parameters such as assay, loss on drying, heavy metal content, and particle size distribution. A Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a cool, dry place. Recommended storage temperature is 15-25°C. Keep away from strong acids.
