Description

Sodium 2-[Methyl(1-Oxooctadecyl)Amino]Ethanesulphonate is a high-purity anionic surfactant and emulsifying agent, valued for its excellent stability and compatibility in demanding formulations. Its primary value lies in its ability to reduce surface tension and enhance the wetting, dispersing, and emulsifying properties of complex chemical systems. This compound is essential for manufacturers in the personal care, textile processing, and industrial cleaning sectors who require reliable performance and consistent quality. CAS No. 149-39-3.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and stabilizer in creams, lotions, and hair care products, ensuring smooth texture and long-term formulation stability.
• Textile Auxiliaries: Used as a wetting agent, leveling agent, and softener in dyeing and finishing processes to improve color uniformity and fabric handle.
• Industrial & Institutional (I&I) Cleaners: Serves as a key surfactant in heavy-duty degreasers, metal cleaners, and hard surface cleaners for superior oil and grease removal.
• Emulsion Polymerization: Functions as an effective emulsifier in the production of synthetic rubbers, latex paints, and acrylic polymers.
• Leather Processing: Employed in fatliquoring and dyeing stages to improve the penetration of oils and dyes, resulting in softer, more uniformly colored leather.
• Agricultural Formulations: Enhances the spreading and adhesion of pesticides and herbicides, improving foliar coverage and efficacy.
