To clarify the properties and behaviors of nonionic surfactants, ternary phase diagrams containing homogeneous and polydispersed P. O. E n-dodeca-nols as a component were studied. 1) The behaviors of homogeneous (N) and polydisperse (P) nonionic surfactants can readily be illustrated in the diagrams as the region of O/W or W/O solubilization, gel formation, etc. 2) The difference between the properties of homogeneous P. O. E. n-dodecanols (N4 and N8) and those of commercial products (P4 and P8) is easy to distinguish in the diagram. 3) The influences of the length and distribution in polyoxyethylen chain upon the phase diagram were discussed. 4) The influences of oil component on ternary systems are evident in those diagram (n-hexane and cyclo-hexane).
