摘要：
The association of the biosurfactants sodium cholate (NaC) and sodium dodecanoate (SDoD) with the neutral water-soluble polymer poly(ethyleneoxide) (PEO) was investigated. The physical-chemical techniques employed were pyrene fluorescence, electrical conductivity, and viscosity analysis. It was found that the formation of mixed complexes of PEO-NaC-SDoD occurs only with high SDoD molar fractions of surfactant mixtures. At low SDoD molar fractions the mixed aggregates behave as in the absence of PEO, with the type of micellar aggregates varying with the composition of the surfactant mixtures from a classical spherical formation for SDoD to micellization of NaC.
