4-octylphenol monoethoxylate

4-Octylphenol monoethoxylate (CAS 2315-67-5) is a short-chain ethoxylated alkylphenol surfactant used as an emulsifier, dispersant, and cleaning agent in industrial formulations.

Where is 4-octylphenol monoethoxylate used?

• Agrochemicals: emulsifier and carrier in pesticide emulsifiable concentrates, improving active ingredient dispersion in water
• Textiles: scouring and dyeing auxiliaries that aid fiber wetting and removal of oils and sizing agents
• Leather processing: degreasing baths and fat-liquoring emulsions requiring controlled HLB surfactants
• Personal care: solubilizer or emulsification aid in rinse-off systems
• It is a low-ethoxylate member of the alkylphenol ethoxylate family, distinct from longer-chain variants such as Triton X-100.

Good to know: Distinct from longer-chain variants such as Triton X-100. Buyers should confirm ethylene oxide adduct count and purity specification, as these affect HLB value and application fit.
