Description

Polyoxyethylene(7.5) Nonylphenyl Ether is a nonionic surfactant belonging to the alkylphenol ethoxylate (APEO) family. This versatile chemical is valued for its excellent emulsifying, wetting, and dispersing properties in aqueous systems. It serves as a critical processing aid and formulation component across numerous industries, including agrochemicals, textiles, industrial cleaning, and coatings.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide and herbicide concentrates (ECs, SCs).
• Industrial & Institutional (I&I) Cleaning: Used in heavy-duty degreasers, metal cleaners, and textile scouring agents for its detergency.
• Textile Processing: Functions as a leveling agent, dye dispersant, and scouring aid in fabric treatment.
• Coatings & Paints: Employed as a pigment grinding aid and dispersant to improve color stability and application properties.
• Metalworking Fluids: Serves as an emulsifier in soluble oils and synthetic coolants.
• Paper & Pulp Industry: Used in de-inking processes and as a dispersant for coatings.
• Emulsion Polymerization: Acts as a surfactant in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
