Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and performance. Keep away from strong oxidizing agents and incompatible materials.
