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). This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption, which may affect product properties.
