Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flames. Due to its light-sensitive nature, handling should be performed under subdued lighting or using amber glass containers where prolonged exposure is expected.
