Quality Control

Our Hydroxydinonylbenzenesulphonic Acid is manufactured under a rigorous quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications, with a focus on consistent acid value, purity, and color. 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, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its strong acid/organic solvent nature, containers must be kept tightly sealed to prevent moisture absorption and maintain product integrity. Recommended storage temperature is 15-25°C.
