Quality Control

Our production of Benzenesulfonic Acid, 4-Hydroxy-, Monosodium Salt, Polymer With Formaldehyde And Urea adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent performance and meets specifications for critical parameters such as active content, pH, viscosity, and density. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent moisture absorption and caking. Keep away from strong oxidizing agents.
