Quality Control

Our Octadecanoic Acid, Epoxy-, Octyl Ester is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, epoxy content, and physical properties meet defined specifications. Certificates of Analysis (COA) detailing key parameters such as assay, epoxy value, acid 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, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve product integrity. Keep away from strong oxidizing agents.
