Quality Control

Our C18 Dihydroceramide is manufactured under strict quality management systems. Each batch is characterized and tested to ensure identity, purity, and consistency, meeting the stringent requirements for research and cosmetic-grade materials. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), identification (IR, NMR), and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, as the compound is easily oxidized. For short-term use, store desiccated at 2-8°C. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
