Quality Control

Our Dibutyloctyl Sebacate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. The product is tested against rigorous internal specifications that assess key parameters such as ester content, acid value, color, and moisture. While not certified as food or pharmaceutical grade, it is produced to meet the high standards required for industrial and specialty chemical applications. A Certificate of Analysis (COA) detailing all quality parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to minimize moisture absorption and contamination.
