Quality Control

Our Dodecyldimethylammonium Chloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, activity, and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, moisture content, and impurity profiles. Our production adheres to cGMP principles where applicable, ensuring reliability for sensitive applications in biocidal and personal care formulations.

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 absorption of atmospheric moisture. Keep away from strong oxidizing agents.
