Description

3-(N,n-Dimethylmyristylammonio)Propanesulfonate is a high-purity zwitterionic surfactant belonging to the sulfobetaine class. This compound is valued for its excellent compatibility, mildness, and stability across a wide pH range, making it a versatile ingredient in demanding formulations. It is primarily sought after by manufacturers in the personal care, pharmaceutical, and industrial cleaning sectors for its superior performance as a foam booster, viscosity modifier, and conditioning agent.

Application

• Personal Care & Cosmetics: As a primary or co-surfactant in shampoos, body washes, and facial cleansers for gentle cleansing and rich foam.
• Pharmaceutical Formulations: Used in topical creams, ointments, and medicated shampoos for its emulsifying properties and skin compatibility.
• Industrial & Institutional Cleaners: An effective component in hard surface cleaners, degreasers, and dairy cleaners where stability in acidic or alkaline conditions is required.
• Biotechnology & Protein Research: Employed as a mild detergent in cell lysis buffers and for solubilizing membrane proteins without denaturation.
• Textile & Leather Processing: Acts as a wetting agent, softener, and antistatic agent in various processing baths.
• Enhanced Oil Recovery (EOR): Investigated for use in surfactant-polymer flooding formulations due to its tolerance to high salinity.
