Hexadecyldimethylsulfopropylbetaine (HDSB)
CAS 2281-11-0
Tetradecyldimethylsulfopropylbetaine (CAS 2281-11-0) is a high-purity zwitterionic sulfobetaine surfactant, typically supplied as a clear to light-yellow liquid (industrial grade). As a non-denaturing detergent, HDSB is widely used in biochemical research for the solubilization, purification, and crystallization of membrane proteins, and is fully compatible with techniques such as chromatography, electrophoresis (including 2D-PAGE), and mass spectrometry. In personal care and industrial applications, it functions as a mild amphoteric surfactant, providing foam boosting, thickening, conditioning, emulsifying, and antistatic properties in formulations such as shampoos, body washes, detergents, fabric softeners, adhesives, and inks. However, due to its low biodegradability and potential aquatic toxicity, care should be taken to avoid direct environmental release, and disposal must follow hazardous waste regulations.
>> Main Uses
Hexadecyldimethylsulfopropylbetaine (HDSB, CAS 2281-11-0) is a high-purity zwitterionic sulfobetaine surfactant widely used as a non-denaturing detergent for the solubilization, purification, and crystallization of membrane proteins in biochemical research, fully compatible with techniques such as chromatography, 2D electrophoresis, and mass spectrometry; in personal care formulations, it functions as a mild amphoteric surfactant that provides foam boosting, thickening, and conditioning effects in shampoos, body washes, facial cleansers, and hair color products; and in industrial applications, it serves as an effective emulsifier, wetting agent, antistat, and corrosion inhibitor in detergents, fabric softeners, adhesives, inks, coatings, and metalworking fluids.
