The reduced solubility of organic materials in practically perfluorinated microemulsions 1 led to the preparation of perhydrogenated microemulsions containing the appropriate perhydrogenated oil and cosurfactant, but in which the surfactant has been chosen in order to match the critical micellar concentration of the previously perfluorinated carboxylic acid. The pseudo-ternary phase diagram of those perhydrogenated microemulsions show larger domains of oilwater and wateroil microemulsions these areas remain, however, at the same range of water, oil and surfactantcosurfactant percentages as found in the case of the practically perfluorinated microemulsions. We are interested to test if a high probability of thermodynamically stable mixtures of perfluorinated and perhydrogenated microemulsions can be prepared within those areas. This work would directly lead to a usefull method to produce mixed perfluorinatedperhydrogenated microemulsions.
