Quality Control

Our 3,6,9,16,19-Pentaoxahenicosane-1,21-Diyl Dilaurate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets high-purity specifications for critical parameters such as assay, acid value, and saponification value. A Certificate of Analysis (COA) detailing these results is provided with each shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent oxidation and moisture absorption. Keep away from strong oxidizing agents.
