Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and degradation. Keep away from strong oxidizers and acids.
