Quality Control

Our Magnesium Aluminosilicate is manufactured under a strict quality management system. It can be produced to meet various pharmacopeial standards, including USP-NF and Ph. Eur. monographs, as well as FCC specifications for food-grade applications. Every batch undergoes rigorous testing for identity, purity, and physical characteristics. Comprehensive Certificates of Analysis (COA) are provided and available upon request to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect flow properties and performance.
