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) and light-sensitive; therefore, containers must be kept sealed when not in use to prevent degradation and moisture absorption.
