Description

Poly(Oxy-1,2-Ethanediyl), α-[2-[Octadecyl(2-Sulfoethyl) Amino]Ethyl]-ω-Hydroxy-, Monosodium Salt is a high-purity, nonionic-anionic surfactant with excellent emulsifying and wetting properties. This compound is valued for its ability to stabilize formulations and reduce surface tension in demanding industrial processes. It is primarily used by manufacturers in the agrochemical, textile, and personal care industries seeking reliable performance and batch-to-batch consistency.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates, improving sprayability and plant coverage.
• Textile Processing: Used as a wetting agent and dye leveling assistant in fabric pretreatment and dyeing baths.
• Industrial & Institutional Cleaners: Serves as a surfactant in heavy-duty degreasers and cleaning formulations for its stability in alkaline conditions.
• Personal Care & Cosmetics: Functions as a mild emulsifier and foam booster in select rinse-off products like shampoos and body washes.
• Paints & Coatings: Employed as a dispersing agent to stabilize pigment suspensions and improve color development.
• Metal Working Fluids: Enhances the emulsification of oils in synthetic and semi-synthetic coolants and lubricants.
