Description

2-(3-Pentadecyl-4-Sulfophenoxy)Butanoic Acid is a specialized anionic surfactant and intermediate known for its unique combination of a hydrophobic alkyl chain and hydrophilic sulfonate and carboxylate functional groups. This molecular structure is critical for its role as a high-performance emulsifier, dispersant, and wetting agent in demanding formulations. It is essential for industrial chemists and formulators in sectors requiring precise surface activity and chemical stability under acidic conditions.

Application

• Industrial Surfactant & Emulsifier: Key component in the formulation of specialty detergents, industrial cleaners, and emulsion polymerization processes.
• Textile Processing Auxiliary: Used as a wetting agent, dispersant, and leveling agent in dyeing and finishing operations.
• Enhanced Oil Recovery (EOR): Investigated for use in chemical flooding formulations to reduce interfacial tension and improve oil displacement.
• Pigment & Filler Dispersion: Effective dispersing agent for inorganic pigments and fillers in coatings, inks, and composite materials.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide formulations to improve spreading and adhesion on plant surfaces.
• Personal Care Intermediate: Serves as a precursor or additive in the synthesis of specialized surfactants for cosmetic and personal care products.
