Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under low-light conditions to maintain stability and prevent degradation.
