Quality Control

Our Sulfurous Acid, Monosodium Salt, Polymer With Formaldehyde And Urea is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance. Key parameters such as active content, pH, and solubility are verified. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive) and easily oxidized; containers must be kept tightly sealed after opening to minimize exposure to air and moisture. Keep away from strong oxidizing agents.
