Quality Control

Our Dodecyl Benzenesulfonic Acid, Sodium Salt is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high performance. Production adheres to relevant industry standards, and each lot is tested against key parameters including active matter content, free oil, and moisture. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee product integrity and 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); keep the container tightly sealed when not in use to prevent caking or degradation due to moisture absorption. Keep away from strong oxidizing agents.
