Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
