Quality Control

Our Silicic Acid (H2Sio3), Calcium Salt (1:1) is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, physical properties, and performance. Certificates of Analysis (COA) are provided with every shipment, and we can support compliance with relevant standards such as FCC for food grade or USP for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect flow properties and performance. Keep away from incompatible materials such as strong acids.
