Investigation of sodium dodecyl sulfate+acetamide, formamide aqueous mixtures of various concentrations has been performed by dielectric relaxation spectroscopy (TDR-time domain reflectometry) technique 303 K. The relaxation times were determined through the Debye method and relative viscosities of solution. The linear increase of relative viscosity has the same increasing trend as dodecyl sulfate concentrations up to 80 mM. The superposition of relaxation time between water and micelle through the rotation phenomena, whereas inside the micelle by hydrophobic phenomena, is found and discussed in light of obtained results and justified.
