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); therefore, the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
