Description

Sulfobetaine CAS NO 4727-41-7 is a high-purity zwitterionic surfactant belonging to the alkyl sulfobetaine chemical class. This compound is valued for its excellent amphoteric properties, offering superior stability across a wide pH range and compatibility with other surfactants. It is a critical raw material for formulators in the personal care, home care, and industrial cleaning sectors who require mild, high-foaming, and viscosity-modifying ingredients.

Application

• Personal Care Formulations: Used as a primary or co-surfactant in mild shampoos, body washes, facial cleansers, and baby care products for its gentle cleansing and rich lather.
• Home Care & Industrial Cleaners: An effective component in dishwashing liquids, hard surface cleaners, and industrial degreasers, providing excellent wetting and emulsifying power.
• Enhanced Oil Recovery (EOR): Employed in chemical flooding formulations to reduce interfacial tension between oil and water, improving oil displacement efficiency.
• Textile & Leather Processing: Acts as a leveling agent, softener, and antistatic agent in dyeing and finishing processes.
• Protein Chemistry & Biochemistry: Serves as a mild detergent for cell lysis and membrane protein solubilization while maintaining protein functionality.
• Coatings & Inks: Functions as a dispersant and wetting agent to improve pigment dispersion and stability in aqueous systems.
