Quality Control

Our Octadecanoic Acid, 1,2,3-Propanetriyl Ester, Polymd., Oxidized is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in parameters such as acid value, peroxide value, viscosity, and polymer distribution. Certificates of Analysis (COA) documenting these specifications 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 and heat sources.
