The polarographic and electrocapillary curve methods have been used to determine the maximum suppression point (MSP), polarographic micelle point (PMP) and critical micelle concentration (cmc) of some polyoxyethylated nonionic surfactants, viz., Tween 20, Tween 40 and Tween 80. The cmc values thus obtained have been compared with the values obtained by surface tension, iodine solubilization, spectral dye and radiometric methods.
