Quality Control

Our Phosphoric Acid, Isononyl Ester, Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets defined specifications for identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) documenting purity, pH, moisture content, and other critical parameters is provided with every shipment to guarantee supply reliability and performance consistency for your processes.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
