By considering the so-called microemulsions as hydrocarbons dissolved in the homogeneous alcoholic phase, L2, present in the systems water-surface-active substance-alcohol, the phase equilibria and NMR spectra of the micellar solutions can be interpreted in the following way. The presence of the dissolved hydrocarbon in the hydrocarbon part of the micellar solution enhances the solubilization of water in the micelles owing to changes of the packing conditions of the soap and alcohol hydrocarbon chains. At very high concentrations of hydrocarbon, the solubilization of water is strongly reduced owing to the transport of alcohol from the micelles into the hydrocarbon part of the solution. (18 refs.)
