Quality Control

Our Octadecanoic Acid 2-Hydroxy-3-(2-Hydroxy-1-Oxopropoxy)Propyl Ester is produced under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and saponification value are available upon request. We can supply grades compliant with relevant standards for cosmetic (ISO 22716), pharmaceutical (cGMP), or food (FCC) applications based on customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen blanket). Keep away from strong oxidizing agents and heat sources.
