The drop weight method was used to determine the interfacial tension between organic liquid and solutions of different concentrations of the surfactant, sodium lauryl sulphate (SLS), using Hadkar factor. Two experiments were performed to determine the interfacial tension. In the first experiment the drop weight method was used to determine the interfacial tension between water or aqueous surfactant solutions and benzene (liquid lighter than water) using Hadkar factor H1. In the second experiment the drop weight method was used to determine the interfacial tension between water or surfactant solutions and carbon tetrachloride (liquid heavier than water) using Hadkar factor H2. The plot of interfacial tension between benzene or CCl4 and SLS solutions versus concentration of surfactant solution was used to determine the critical micelle concentration (CMC) of the surfactant. The results were in good agreement with the reported values of CMC for SLS showing the utility of Hadkar factor in the determination of CMC of surfactants.
