Description

Nonoxynol-5 is a non-ionic surfactant belonging to the alkylphenol ethoxylate family, specifically a polyethoxylated nonylphenol with an average of 5 moles of ethylene oxide. This compound is valued for its effective wetting, emulsifying, and detergent properties in aqueous systems. It serves as a critical intermediate and functional additive across several industrial sectors, including agrochemicals, textile processing, and industrial cleaning formulations.

Application

• Agrochemical Adjuvant: Used as a wetting agent, emulsifier, and dispersant in pesticide and herbicide formulations to enhance spray coverage and efficacy.
• Textile Processing Aid: Functions as a scouring, wetting, and leveling agent in dyeing and finishing processes for natural and synthetic fibers.
• Industrial & Institutional (I&I) Cleaning: A key surfactant in heavy-duty cleaners, degreasers, and detergent blends for hard surface cleaning.
• Emulsion Polymerization: Acts as an emulsifier and stabilizer in the production of acrylic, vinyl acetate, and other polymer lattices.
• Metalworking Fluids: Incorporated as an emulsifier and lubricity agent in soluble oils and coolants.
• Pulp & Paper Industry: Used in de-inking processes and as a dispersant for pigments and fillers.
