Quality Control

Our Sodium Octadecyl Phosphonate is manufactured under a quality management system and undergoes rigorous analytical testing to ensure batch-to-batch consistency and compliance with agreed specifications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, moisture content, and impurity profiles. For customers with specific regulatory needs, we can discuss compliance with relevant frameworks such as REACH.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
