Description

Sulfuric Acid, Mono-C12-18-Alkyl Esters, Sodium Salts is a high-purity anionic surfactant belonging to the alkyl sulfate family, derived from a blend of C12 to C18 fatty alcohols. This compound is valued for its excellent foaming, wetting, and emulsifying properties, making it a versatile workhorse in demanding industrial and personal care formulations. Key industries that rely on this surfactant include detergents, cosmetics, textile processing, and emulsion polymerization, where consistent quality and performance are critical.

Application

• Primary Surfactant in Detergents & Cleaners: Used in liquid soaps, dishwashing liquids, and industrial cleaners for its robust foaming and grease-cutting abilities.
• Personal Care & Cosmetics: Serves as a base surfactant in shampoos, body washes, and bubble baths, providing a rich lather and mild cleansing.
• Textile Processing Auxiliary: Acts as a wetting agent, scouring agent, and emulsifier in fiber preparation and dyeing processes.
• Emulsion Polymerization: Functions as an emulsifier and stabilizer in the production of synthetic rubbers, latex paints, and polymer dispersions.
• Agricultural Formulations: Used as an adjuvant in pesticide and herbicide sprays to improve wetting and spreading on plant surfaces.
• Industrial Lubricants & Metalworking Fluids: Employed as an emulsifier and corrosion inhibitor in soluble oils and coolants.
