The critical micelle concentrations (CMC) of mixtures of nonionic surfactants with the same hydrocarbon, <I>i.e.</I> dodecyl group, and with various chain lengths of ethylene oxide, were determined. The observed values were compared with the values calculated by means of the equation derived from the pseudo-phase separation model on the assumption that the mixed micelle is a perfect solution. A good agreement between observed and calculated values was obtained in the mixtures of the surfactants with six or more ethylene-oxide units. However, the observed values of the two-component mixture, one component with five ethylene-oxide units, showed a small deviation from the calculated values. The difference between the above two cases was explained from the viewpoint of the most suitable packing of the first six or fewer ethylene-oxide units near the micelle core in the micelle state.
