Quality Control

Our Sodium Hydroxydinonylbenzenesulphonate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with agreed specifications. A Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and ionic composition is provided with each shipment to guarantee traceability and product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
