Description

Polyoxyethylene(5) Nonylphenyl Ether is a nonionic surfactant belonging to the alkylphenol ethoxylate (APE) family, characterized by its hydrophilic polyoxyethylene chain and hydrophobic nonylphenyl group. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a versatile processing aid and formulation component. It is primarily utilized in industrial cleaning formulations, agrochemicals, textile processing, and as an intermediate in chemical synthesis.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key surfactant and emulsifier in heavy-duty degreasers, metal cleaners, and hard surface cleaners.
• Agrochemical Formulations: Used as an emulsifier and wetting agent in pesticide and herbicide concentrates to improve sprayability and plant coverage.
• Textile Processing: Serves as a scouring, dyeing, and leveling agent to enhance the wetting and penetration of processing baths.
• Chemical Intermediate: Employed in the synthesis of other specialty surfactants and chemical derivatives.
• Emulsion Polymerization: Functions as an emulsifier and stabilizer in the production of acrylic, vinyl acetate, and other polymer emulsions.
• Metalworking Fluids: Incorporated as an emulsifier in soluble oils and coolants to stabilize oil-in-water emulsions.
• Pulp & Paper Industry: Used in de-inking processes and as a dispersant for pigments and fillers.
