Quality Control

Our Potassium Hydrogen Malate is produced and tested under a stringent quality management system. We offer grades suitable for food, pharmaceutical, and technical applications, with quality assurance aligned to relevant standards such as FCC and USP where applicable. Certificates of Analysis (COA) documenting purity, identity, and safety parameters are available for every batch upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
