Description

Disodium 9-(Sulphonatooxy)Octadecanoate is a specialized anionic surfactant derived from octadecanoic acid. This compound is valued for its unique combination of hydrophobic alkyl chain and hydrophilic sulphonatooxy group, providing excellent emulsifying and wetting properties. It is primarily utilized in the formulation of high-performance industrial cleaning products, textile auxiliaries, and specialized chemical intermediates where stable emulsions and surface activity are critical.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key emulsifier and wetting agent in heavy-duty degreasers, metal cleaners, and floor care formulations.
• Textile Processing: Used as a scouring agent, dyeing assistant, and softener component to improve fiber wetting and chemical penetration.
• Emulsion Polymerization: Serves as a surfactant in the production of synthetic latexes for paints, coatings, and adhesives.
• Leather Processing: Employed in beamhouse operations and fatliquoring for efficient wetting and emulsification of natural fats.
• Agricultural Adjuvants: Enhances the spreading and sticking of pesticides and herbicides on plant surfaces.
• Personal Care (Rinse-off products): Can be used as a secondary surfactant in specialized cleansing systems requiring high electrolyte tolerance.

Quality Control

Our Disodium 9-(Sulphonatooxy)Octadecanoate is manufactured under a strict quality management system. Each batch is tested to ensure consistent chemical composition, purity, and performance characteristics. A comprehensive Certificate of Analysis (COA) detailing assay, identification, and impurity profiles is provided with every shipment to guarantee it meets your technical specifications.

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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality.
