Quality Control

Our Zinc Phenolsulfonate is produced under a rigorous quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and heavy metal content, aligning with industrial and pharmaceutical-grade requirements. A comprehensive Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance.

Storage
