Monodisperse nonionic surfactant molecules, based on aspartic or glutamic acid, with two hydrogenated or fluorinated fatty amide chains in the hydrophobic part and one polyoxyethylene methoxy‐capped chain (EOn−Me) in the hydrophilic head group have been synthesized. These compounds are structural mimics of natural lecithins. Their solubility in water or in formamide and the surface activities at 60°C have been measured and discussed in comparison with lecithin analogues that contained short chains. The compounds reported in this study showed physicochemical properties comparable with those of lecithins.
