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 sealed to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
