Quality Control

Our Fatty Acids, Coco, 2,2-Dimethyl-1,3-Propanediyl Esters are produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as acid value, saponification value, color, and odor 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, well-ventilated area at room temperature (15-25°C/59-77°F). As this material is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize contact with air. Keep away from strong oxidizing agents and heat sources.
