Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from incompatible materials.
