Description

Sodium n-Undecyl Sulphate is a high-purity, synthetic anionic surfactant derived from undecyl alcohol. This compound is valued for its excellent wetting, foaming, and emulsifying properties, making it a versatile ingredient in specialized formulations. It is primarily used by manufacturers in the personal care, industrial cleaning, and textile processing sectors who require consistent performance and reliable supply chain partners.

Application

• Personal Care Formulations: Acts as a primary or secondary surfactant in shampoos, body washes, and facial cleansers for its mildness and foam stability.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, floor cleaners, and metalworking fluids for its effective wetting and emulsification.
• Textile Processing: Serves as a wetting agent and detergent in scouring, dyeing, and finishing operations.
• Emulsion Polymerization: Functions as an emulsifier in the production of synthetic latexes and polymers.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
• Laboratory & Research: Employed as a model surfactant in colloid and interface science studies.
