Analysis of non-ionic surfactants of the “ethoxylated Alkyl Phenol” type


Ethoxylated Alkyl Phenol or APE are synthesized for their surfactant properties allowing better dispersion of liquids and their emulsification. They are commonly used in the textile industry as wetting agents, dispersants, emulsifiers or even as detergents . They are also used in paints, metal treatment, drilling, oil extraction and production, water treatment ( flocculants) , biocides and cosmetic products ( shampoos, household cleaners, etc.).

The distribution of ethoxylated units (distribution) and hydrophobic units is to be directly linked with the surfactant properties and their analysis is possible by UPLC/TOF-MS.
