Solution properties of anionic sesame fatty acid methyl esters sulphonate surfactant and sodium dodecyl sulphate standard

<p>The relationship between specific conductivity and surfactant concentration was used to determine the solution properties of synthesized anionic sesame fatty acid methyl esters sulphonate (SEFAMESO) surfactant and sodium dodecyl sulphate (SDS) standard. The solution properties evaluated included critical micelle concentration (CMC) values, counter-ion binding degree (<em>β</em>) and thermodynamic parameters namely, Gibbs free energy (<i>∆G°</i>_{_{<i>_mic</i>}}), enthalpy (<i>∆H°</i>_{_{<i>_mic</i>}}) and entropy (<i>∆S°</i>_{_{<i>_mic</i>}}<i>)</i> of micellization.</p>
