Bicontinuous microemulsions are continuously connected interwoven domains of oil and water. In a fishlike phase diagram, this type of microemulsion structure is located in the single phase region, very close to the fishtail point, where the three-, two- and one phase region meet.
Bicontinuous microemulsions are formed by the highest amounts of oil and water and the lowest necessary amount of surfactant. We study the bicontinuous region of a quaternary system water/rapeseed methyl ester/sugar surfactant/pentanol, which is environmental compatible and hence, a promising candidate for a modern decontamination medium.
We present results from studies of the phase behavior of quaternary systems. Moreover, the influence of an additional active component like oxidizing agents and enzymes is discussed.
