Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at controlled room temperature (15-25°C). The container must be kept tightly sealed immediately after use to prevent moisture absorption and caking. Store away from incompatible materials such as strong acids.
