Very lipophilic additives are able to substantially improve the solubilization in surfactant-oil-water microemulsions. The so-called lipophilic linker effect is studied, and its role is discussed. It is shown that the presence of a very lipophilic amphiphilic additive may improve substantially the solubilization in microemulsions. This substance is called a lipophilic linker because its preferential orientation in the oil layers next to the interface might provide some ordering of the oil molecules as well as an additional link with the surfactant. Both effects result in a higher interaction on the oil side of the interface. 21 refs., 5 figs., 1 tab.
