Quality Control

Our Sodium Aluminum Silicate is manufactured under a stringent quality management system. Production adheres to relevant food-grade (FCC, JECFA) and industrial specifications. Every batch is tested for critical parameters including assay, moisture content, particle size distribution, and heavy metal limits. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee compliance and traceability.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent moisture absorption and caking.
