Quality Control

Our Aluminum Magnesium Carbonate Hydroxide Hydrate is manufactured under a strict quality management system. Production batches undergo rigorous analytical testing to ensure consistent composition, purity, and performance. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing parameters such as assay, heavy metal content, and loss on drying. Specifications can be tailored to meet USP/NF, Ph. Eur., or other relevant pharmacopeial and industrial standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a 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 and carbon dioxide, which can alter its properties.
