Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Sulfo-.Omega.-(Octadecyloxy)-, Ammonium Salt is a high-purity, nonionic-ionic hybrid surfactant belonging to the alkyl ether sulfate class. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a critical performance additive in demanding formulations. It is primarily sought after by manufacturers in the agrochemical, coatings, textile, and personal care industries for creating stable and effective end-products.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide concentrates (EC, SC, EW) and adjuvant systems to enhance spray coverage and biological efficacy.
• Industrial & Institutional Cleaners: Provides superior wetting and soil suspension in heavy-duty degreasers, hard surface cleaners, and dairy detergents.
• Coatings & Paints: Used as a pigment grinding aid and dispersant to improve color development, stability, and application properties in water-based systems.
• Textile Processing: Functions as a leveling agent, lubricant, and emulsifier in dyeing baths and fiber finishing operations.
• Personal Care (Rinse-off products): Employed as a secondary surfactant and foam booster in shampoos, body washes, and other cleansing formulations.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic metalworking coolants.
• Paper & Pulp Industry: Utilized as a de-inking agent and dispersant in pulp processing and paper coating formulations.
• Oilfield Chemicals: Applied in drilling muds and completion fluids as an emulsifier and viscosity modifier.
