Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
