Quality Control

Our Fatty Acids, C16-18, Esters With Ethylene Glycol is produced under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for acid value, saponification value, melting point, and appearance. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere such as nitrogen to preserve product integrity. Keep away from strong oxidizing agents.
