Description

Sodium 9-Octadecene-1-Sulphonate is a high-purity anionic surfactant derived from olefin sulfonation. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in aqueous systems. It is primarily utilized in the formulation of industrial and institutional cleaning products, textile processing aids, and emulsion polymerization. Our supply ensures consistent quality and reliable performance for demanding B2B applications.

Application

• Industrial & Institutional (I&I) Cleaners: A key surfactant in heavy-duty floor cleaners, degreasers, and alkaline cleaning formulations for its robust performance.
• Textile Processing: Acts as an effective wetting agent and emulsifier in scouring, dyeing, and finishing baths.
• Emulsion Polymerization: Serves as a primary or co-emulsifier in the production of synthetic latexes for paints, coatings, and adhesives.
• Metal Working Fluids: Used in formulations for its emulsification and surface-wetting capabilities.
• Agricultural Adjuvants: Enhances the spreading and penetration of agrochemicals on plant surfaces.
• Personal Care (Rinse-off products): Found in select formulations for its cleansing and foaming characteristics.
