Quality Control

Our 12-Hydroxystearic Acid Ethyl Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting key parameters such as assay, hydroxyl value, and acid value is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong alkalis and incompatible materials such as strong oxidizing agents. The container should be kept tightly sealed when not in use to minimize moisture absorption.
