Quality Control

Our Oxyresveratrol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and UV spectroscopy, to ensure it meets the high standards required for cosmetic and nutraceutical applications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing all specification results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the primary container. Keep away from heat and incompatible materials.
