Quality Control

Our Disodium 4-Octadecyl 2-Sulphonatosuccinate is manufactured under a stringent quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent purity, performance, and safety. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical parameters is provided with every shipment to guarantee traceability and compliance.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and flow properties.
