Description

3-(Dimethyloctadecylazaniumyl)Propane-1-Sulfonate is a high-purity zwitterionic surfactant belonging to the sulfobetaine class, characterized by its unique combination of a long hydrophobic alkyl chain and a hydrophilic sulfonate group. This structure provides excellent stability, compatibility, and mildness, making it a valuable ingredient for demanding formulations. It is essential for industries requiring advanced surface-active agents with superior performance under a wide range of conditions.

Application

• Personal Care & Cosmetics: As a primary surfactant or co-surfactant in shampoos, body washes, and facial cleansers for its mildness and skin compatibility.
• Biotechnology & Biochemistry: Used in protein purification, cell lysis buffers, and electrophoresis due to its ability to solubilize membrane proteins without denaturation.
• Enhanced Oil Recovery (EOR): Acts as a key component in surfactant-polymer flooding formulations to reduce interfacial tension and improve oil displacement.
• Industrial & Institutional Cleaning: Formulated into hard surface cleaners, degreasers, and specialty detergents where stability in electrolytes is required.
• Textile & Leather Processing: Employed as a wetting agent, dispersant, and softener in various treatment baths.
• Pharmaceuticals: Utilized as an excipient in certain drug delivery systems and topical formulations.
• Agrochemicals: Serves as an adjuvant in pesticide and herbicide formulations to enhance spreading and adhesion.
• Research & Development: A critical reagent for studying surfactant micelle formation, interfacial phenomena, and colloidal systems.
