Quality Control

Our Disodium (Sulphonatophenoxy)Tetrapropylenebenzenesulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) detailing key specifications such as assay, moisture content, and impurity profiles are available upon request to support your quality assurance protocols.

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 after opening to prevent absorption of atmospheric moisture, which can affect product quality.
