Quality Control

Every batch of Polysaccharide S-156 is manufactured under a rigorous quality management system. Our products undergo comprehensive analytical testing to ensure identity, purity, and consistency, meeting the high standards required for pharmaceutical and cosmetic applications. A Certificate of Analysis (COA) detailing specific test results for parameters such as assay, microbial limits, and heavy metals is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture uptake, which can affect product performance.
