Quality Control

Our 2-Ethylhexyl Isononyl Phthalate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, acidity, and other critical parameters. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee consistency and traceability for our global B2B clients.

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.
