Quality Control

Our Isononyl Nonyl Phthalate 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 monitor key parameters such as ester content, acid value, color, and specific gravity. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your technical requirements.

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 bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and contamination.
