Description

n-Dodecyl-N,n-Dimethyl-3-Ammonio-1-Propanesulfonate is a high-purity zwitterionic surfactant belonging to the sulfobetaine class. This compound is valued for its excellent solubility, stability across a wide pH range, and mildness, making it a versatile ingredient in demanding formulations. It is essential for industries requiring advanced surface-active agents with superior compatibility and performance. Key sectors include personal care, pharmaceuticals, biotechnology, and specialized industrial cleaning.

Application

• Personal Care Formulations: Used as a primary or co-surfactant in mild shampoos, body washes, and facial cleansers due to its skin-friendly and non-irritating properties.
• Biochemical Research & Diagnostics: Serves as a key detergent in membrane protein solubilization and stabilization, critical for electrophoresis and chromatography.
• Pharmaceutical Delivery Systems: Employed in the development of liposomes and other nano-carriers to enhance drug solubility and bioavailability.
• Industrial & Institutional Cleaners: Acts as a wetting and dispersing agent in hard surface cleaners, offering stability in concentrated electrolyte solutions.
• Enhanced Oil Recovery (EOR): Investigated for use in surfactant-polymer flooding due to its tolerance to high salinity and temperature in reservoir conditions.
• Textile & Leather Processing: Functions as a leveling agent, softener, and antistatic agent in dyeing and finishing processes.
