Abstract: Density and viscosity data of proline (Pro) in sodium dodecyl sulfate/cetyltrimethylammonium bromide/poly (oxyethylene) isooctyl phenyl ether in formamide were measured at 298.15, 303.15, 308.15, and 313.15 K and 0.1 MPa. The density data were utilized to evaluate standard partial molar volumes (φ0 v) and partial molar isobaric expansibility (φ0 E). The viscosity data were used to evaluate A-and B-coefficients, free energy of activation of viscous flow (⊿μ0*1 ) and (⊿μ0*2 ), per mole of solvent and solute respectively, enthalpy (⊿H*) and entropy (⊿utilized in the qualitative elucidation of the Pro-surfactant/formamide and Pro-Pro interactions in the present systems.

Key words: Partial molar volume, Viscosity coefficient, Interaction
