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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
