Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place with controlled humidity. Ideal storage temperature is between 15°C and 25°C. Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and CO2. Store away from strong acids and incompatible materials.
