      abstract     = {Microemulsion systems with water, toluene and nonionic
                      surfactants are interesting for application due to the
                      excellent solvent properties of aromatic hydrocarbons. In
                      this study, the pseudo-binary phase diagram
                      (“fish-diagram”) of such a ternary system was
                      investigated using a branched technical alkyl
                      polyethoxylate. Lutensol ON 50 (i-C10E5) was considered a
                      suitable surfactant. The system with technical branched
                      i-C10E5 exhibits very long and for compositions near optimum
                      solubilization, i.e. the minimum content of surfactant
                      needed for a bicontinuous microemulsion, extremely long
                      times for equilibration. In addition to visual observation,
                      qualitative measurements of turbidity were performed with a
                      UV-Vis spectrometer for characterizing the behavior of this
                      unusually sluggish system. Isothermal phase diagrams at 20,
                      25 and 30°C yielded inconsistent results after the change
                      of temperature and the application of mechanical stress for
                      different treatment of the samples. Ternary mixtures of
                      water, toluene, and Lutensol ON 50 seem to form long-living
                      metastable states. The sluggishness and the ambiguous phase
                      behavior of the system are discussed. Inconsistent results
                      are attributed to the slow kinetics of the formation and
                      destruction of liquid crystals and the ability of the system
                      to form miniemulsions within an unusual concentration
                      range.},
