Quality Control

Our production of 2-(Hydroxymethyl)-2-[(Oleoyloxy)Methyl]-1,3-Propanediyl Dioleate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, acid value, iodine value, and peroxide value determination, to ensure consistency and purity meet customer specifications. Certificates of Analysis (COA) documenting all test results are provided as a standard commitment to supply chain transparency and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain product integrity. Keep away from strong oxidizing agents and heat sources.
