Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 2°C and 8°C (refrigerated) for long-term stability, or at controlled room temperature (15-25°C) for short-term storage of sealed units. This product is hygroscopic (moisture-sensitive); ensure the container is kept sealed in a low-humidity environment to prevent caking and degradation.
