Tetradecyldimethylsulfopropylbetaine (TDSB)
CAS 14933-09-6
Tetradecyldimethylsulfopropylbetaine (CAS 14933-09-6) is a high-purity, zwitterionic sulfobetaine surfactant characterized by its exceptional chemical stability across a broad pH range, from strong acidic to strong alkaline conditions. It carries both a quaternary ammonium cation and a sulfonic acid anion within the same molecule, resulting in a net neutral charge and minimal interference with biological or ionic systems. Unlike conventional ionic surfactants, TDSB does not denature proteins, which makes it particularly valuable for membrane protein solubilization while preserving native structure and activity. Its low foaming tendency, excellent wetting properties, and compatibility with anionic, cationic, and nonionic surfactants further enhance its versatility in complex formulations.
>> Main Uses
Tetradecyldimethylsulfopropylbetaine (TDSB, CAS 14933-09-6) is a high-purity zwitterionic surfactant widely used for the non-denaturing solubilization and stabilization of membrane proteins in biochemical and structural biology research, as a high-performance cleaning agent in acidic and alkaline industrial detergents and hard surface cleaners, as a mild foam-boosting and low-irritation surfactant in personal care products such as shampoos and body washes, as a viscoelastic surfactant (VES) in clean fracturing fluids for oil and gas well stimulation, as a structure-directing agent in mesoporous material and nanoparticle synthesis, as a component in cell lysis buffers and diagnostic kits including ELISA, and as a leveling, wetting, and antistatic agent in textile and leather processing.
