surfactant, SDS, structure formation, solvation, micelles, binary water–ethanol solutionsAbstract
The processes of dielectric relaxation of sodium dodecyl sulfate (SDS) solutions were studied in a range of concentrations in a binary water–ethanol solvent at various alcohol concentrations. It was shown that ethanol at concentrations below 40% does not interfere with the formation of SDS micelles, and at a higher ethanol content, surfactant micelles do not form. However, NMR data show the presence of small associates, most likely SDS dimers, the properties and mobility of which depend on the composition of the water–ethanol medium, in solutions with high alcohol concentrations. Transformations in the structure and size of the complexes observed upon changing the ethanol content in the solution are discussed.
