Quality Control

Our production of Polyethylene,Propyleneglycol (β-Naphthyl) (3-Sulfopropyl) Diether, Potassium Salt adheres to a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency, identity, and purity meet the agreed specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical parameters is provided with each shipment, ensuring full traceability and compliance for your R&D or manufacturing processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a cool, dry place. For long-term storage, consider using a desiccant. Store at controlled room temperature (typically 15-25°C) away from incompatible materials.
