ABSTRACT

The performance of two palm-based anionic surfactants, sodium lauryl sulphate (SLS) and sodium lauryl ether sulphate (SLES), and a non-ionic surfactant, alkyl polyglycoside (APG) was studied. The parameters measured were critical micelle concentration, surface tension, detergency and foaming. The combination of both SLS:APG and SLES:APG both at ratio 6:4, achieved the lowest surface tension compared to SLS and SLES alone. Subsequently, the best detergency was also found at the same ratio for the SLS:APG and SLES:APG systems. These surfactant mixtures also enhanced the foam volume and stability
