Description

Alkyl-(C20-C24)-Benzenesulfonic Acid Methyl Ester is a high-purity, long-chain alkylbenzene sulfonate derivative valued for its excellent surfactant and emulsifying properties. This compound is engineered to deliver superior performance in formulations requiring stability and compatibility with hydrophobic systems. It is a critical intermediate and functional additive for manufacturers in the lubricant, industrial cleaning, and specialty chemical synthesis sectors.

Application

• Lubricant & Grease Additive: Acts as an effective emulsifier and anti-wear agent in metalworking fluids and industrial lubricants.
• Industrial Cleaning Formulations: Serves as a key surfactant in heavy-duty degreasers and institutional cleaners for its oil-solubilizing power.
• Emulsion Polymerization: Functions as a stabilizer and emulsifier in the production of synthetic rubbers and polymers.
• Textile Processing: Used as a wetting agent and softener in fiber treatments and dyeing processes.
• Corrosion Inhibitor Intermediate: A precursor in the synthesis of specialty corrosion inhibitors for oilfield and refinery applications.
• Agricultural Adjuvants: Employed as a component in pesticide and herbicide formulations to enhance spreading and adhesion.
