Product Description
N,N-Dimethyl-N-dodecyl-N-(2-hydroxy-3-sulfopropyl)ammonium betaine is a zwitterionic surfactant featuring both hydrophilic and hydrophobic groups in its molecular structure. This amphiphilic nature enables effective surface activity, helping reduce surface tension and support wetting and interfacial performance in suitable formulations.
Depending on its grade and formulation conditions, this surfactant may be used in various aqueous-based systems where surface activity and formulation compatibility are required. Its performance across different pH conditions depends on the overall formulation, concentration, and operating environment. For personal care applications, suitability for sensitive skin should be assessed through appropriate safety and compatibility testing.
