Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere to preserve product integrity.
