Some surface properties of hydroxamic acids, ketones and methyl esters, which all contained long‐chain alkyl[tetra‐(oxyethylene)] group, were measured and compared to clarify the influence of the terminal functional group on surface properties. From the results of cloud point (T cp ), CMC, γ CMC , adsorption area per molecule at the surface (A) and foaming properties, it was proved that hydroxamic acids had better hydrophilicity and showed better surface properties than the corresponding ketones, methyl esters or typical monodisperse nonionic surfactants.
