Description

Sodium 5-Amino-2-Dodecylbenzenesulphonate is a specialized anionic surfactant characterized by its unique combination of a hydrophilic sulphonate group and a hydrophobic dodecyl chain, enhanced by an amino functional group. This molecular structure provides excellent surface activity, emulsifying power, and compatibility, making it a valuable intermediate and functional additive. It is primarily utilized in the formulation of high-performance industrial detergents, agrochemicals, and specialty chemical synthesis where tailored surface properties are critical.

Application

• Industrial & Institutional (I&I) Cleaning: A key surfactant in heavy-duty detergent formulations for industrial equipment, floor cleaners, and degreasers.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticides, herbicides, and fungicides to improve sprayability and target adhesion.
• Textile Processing: Functions as a wetting agent, scouring aid, and dye leveling agent in textile manufacturing and finishing.
• Enhanced Oil Recovery (EOR): Investigated as a chemical surfactant to reduce interfacial tension in oilfield flooding operations.
• Specialty Chemical Synthesis: Serves as a crucial intermediate for synthesizing more complex surfactants and functional dyes.
• Metal Working Fluids: Acts as an emulsifier and corrosion inhibitor in coolants and cutting fluids.
