Quality Control

Our Alkyl(C12-C18) Dimethyl Benzyl Ammonium Chloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, homolog distribution, and impurity profiles. Certificates of Analysis (COA) are provided with every shipment, documenting compliance with relevant standards such as USP-NF, FCC, or customer-specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
