Quality Control

Our Dequalinium Chloride Hydrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and cosmetic applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with every shipment. We can support compliance with relevant pharmacopoeial standards (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
