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 product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
