Organization of amphiphiles, part XII: studies on the interaction of glycine with aqueous micelles of polyoxyethylated nonyl phenols

► The effect of glycine on micellization of polyoxyethylated nonyl phenols of varying oxyethylene units (15 and 20) has been investigated by various methods. ► Glycine stabilizes the micelles of polyoxyethylated nonyl phenol surfactants. ► The micellization of NP-20 is affected more significantly than that of NP-15.
