Quality Control

Our Magnesium Benzoate is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. We offer grades suitable for food, pharmaceutical, and industrial applications, with testing aligned to relevant standards such as FCC and in-house pharmacopeial guidelines. A comprehensive Certificate of Analysis (COA) detailing purity, identification, and impurity profiles is provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation from atmospheric moisture.
