Quality Control

Our Sodium Isooctyl Phthalate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, moisture content, and heavy metals. Our quality commitment supports compliance with relevant industrial and regulatory standards for global supply.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
