Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C / 59-77°F). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents.
