Quality Control

Our Kojic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for cosmetic and food-grade applications. A Certificate of Analysis (COA) detailing purity, identification, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere to minimize oxidation.
