Quality Control

Our Fatty Acids, C16-18, Monoesters With Polyethylene Glycol Ether With Glycerol (3:1) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent composition, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as acid value, saponification value, hydroxyl value, and moisture content 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 controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent clumping or hydrolysis. For long-term storage, consider using an inert atmosphere to minimize oxidation.
