Quality Control

Our Cetylpyridinium Chloride Monohydrate is manufactured under strict quality systems. We offer grades compliant with USP, EP, and FCC monographs, ensuring suitability for pharmaceutical, cosmetic, and food contact applications. Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting full compliance with specifications are available 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). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
