Quality Control

Our Dilinoleic Acid is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot is analyzed against comprehensive specifications, including identity, purity, and critical impurity profiles. Certificates of Analysis (COA) documenting results for key parameters such as acid value, iodine value, and color are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from strong acids, bases, and 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 exposure to air and moisture.
