Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place with minimal humidity exposure. Recommended storage temperature is between 15°C and 25°C. Keep the container tightly sealed when not in use to prevent degradation from atmospheric moisture. Store away from strong alkalis and incompatible materials.
