The solubilisation of natural compound, (+)-usnic acid, in micellar solutions of gemini (N,N’-didecyl-N,N,N’,N’-tetramethylethane-1,2-diyldiammonium dibromide) and heterogemini (decyl 2-[decyl(dimethyl)ammonio]ethylphosphate) surfactants and their equimolar mixture has been studied. The highest solubility was found for gemini surfactant. The relationship between synergism in surface properties of mixture of surfactants and their solubilisation properties is also discussed.
