Description

Poly(Oxy-1,2-Ethanediyl), α-[2-[Hexadecyl(2-Sulfoethyl) Amino]Ethyl]-ω-Hydroxy-, Monosodium Salt is a high-performance, amphoteric surfactant combining the properties of a nonionic polyoxyethylene chain with a cationic amine and an anionic sulfonate group. This unique molecular structure provides exceptional compatibility, stability, and surface activity across a wide pH range, making it a versatile ingredient for demanding formulations. It is primarily utilized in industries requiring advanced wetting, emulsification, and dispersion properties, such as agrochemicals, coatings, and personal care.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in suspension concentrates (SC), emulsifiable concentrates (EC), and wettable powders (WP) for pesticides and herbicides.
• Coatings and Inks: Provides excellent pigment wetting and dispersion stability in water-based and solvent-based coating systems, improving color development and finish.
• Personal Care Products: Used in shampoos, body washes, and facial cleansers as a mild surfactant and foam booster with good skin compatibility.
• Industrial & Institutional Cleaners: Enhances the cleaning efficacy of hard surface cleaners and degreasers through superior emulsification of oils and fats.
• Textile Processing: Serves as a leveling agent, dye dispersant, and softener in various dyeing and finishing operations.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic metalworking fluids.
