Used as a surfactant and emulsifying agent in industrial applications, particularly in coatings, adhesives, and textile processing. Its long alkyl chains provide good hydrophobic characteristics, while the sulfonate group imparts water solubility and enhances surface activity. Commonly employed to stabilize emulsions and reduce interfacial tension between oil and water phases. Also found in some specialty cleaning formulations and as a dispersant in pigment systems due to its ability to improve wetting and particle suspension.
