Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed immediately after use to minimize exposure to air and humidity. Keep away from incompatible materials such as strong oxidizing agents, strong bases, and metals.
