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); therefore, the container must be kept tightly sealed in a dry environment to prevent absorption of moisture, which can affect stability and performance. For long-term storage, consider using desiccants.
