Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Recommended storage temperature is between 2°C and 8°C (refrigerated) to maximize stability, although short-term storage at controlled room temperature (15-25°C) may be acceptable for immediate use. Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, handling should be performed under subdued light or using amber glass containers.
