Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a desiccated environment and allowed to reach ambient temperature before opening to prevent moisture absorption.
