Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize condensation.
