Quality Control

Every batch of Disodium 4-Hexadecyl 2-Sulphonatosuccinate is manufactured and tested to meet stringent internal specifications. Our quality assurance protocol includes identity confirmation, purity assay, and critical impurity profiling to ensure performance and safety for your formulations. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
