Description

Nonoxynol-3 is a non-ionic surfactant belonging to the alkylphenol ethoxylate family, specifically a polyethylene glycol ether of nonylphenol with an average of 3 moles of ethylene oxide. This compound matters for its effective wetting, emulsifying, and dispersing properties at relatively low concentrations. Industries such as agrochemicals, industrial cleaning, and textile processing need it as a key formulation component for products requiring controlled surface activity and compatibility with various chemical systems.

Application

• Agrochemical Emulsifier: Used as a co-emulsifier and wetting agent in pesticide and herbicide formulations.
• Industrial & Institutional (I&I) Cleaners: Acts as a surfactant in heavy-duty degreasers, metal cleaners, and floor care products.
• Textile Processing Aid: Employed in scouring, dyeing, and finishing baths to improve wetting and leveling.
• Latex Stabilizer: Serves as an emulsifier and stabilizer in the production of synthetic latexes and polymer dispersions.
• Oilfield Chemicals: Functions as a component in drilling muds and other production chemicals for its surfactant properties.
• Household Detergents: Used in specialized liquid detergent formulations requiring specific hydrophilic-lipophilic balance (HLB).
