Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and conformance to key physical and chemical parameters. Certificates of Analysis (COA) detailing specific results for parameters such as hydroxyl value, saponification value, and composition are available upon request. We adhere to a quality management system to ensure batch-to-batch consistency and supply reliability for our global B2B customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and prevent contamination.
