Description

4-[[2-[[2-(Dodecylamino)Ethyl]Amino]Ethyl]Amino]-4-Oxo-2-Sulfobutanoic Acid Disodium Salt is a high-purity, specialized anionic surfactant and chelating agent. Its molecular structure, featuring a long hydrophobic alkyl chain and multiple hydrophilic amino, sulfonate, and carboxylate groups, provides excellent surface activity and metal ion binding properties. This compound is essential for formulators in the personal care, industrial cleaning, and textile processing industries seeking advanced performance in complex aqueous systems.

Application

• Personal Care Formulations: Acts as a primary surfactant and conditioning agent in shampoos, body washes, and facial cleansers, offering mildness and rich lather.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaners, and alkaline formulations for its superior wetting, emulsification, and soil suspension capabilities.
• Textile Auxiliary: Functions as a leveling agent, dispersant, and chelant in dyeing and printing processes to ensure uniform color and prevent metal-ion interference.
• Enhanced Oil Recovery (EOR): Investigated as a chemical surfactant for reducing interfacial tension in reservoir flooding applications.
• Metal Treatment & Plating: Serves as a complexing agent in electroplating baths and metal surface treatment solutions to stabilize bath chemistry and improve finish quality.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to improve spreading, adhesion, and penetration on plant surfaces.
