Abstract
Abstract
The physical and chemical properties of sodium lauryl glutamate were systematically investigated in this work. To determine the critical micelle concentration (CMC) of sodium lauryl glutamate, the surface tension was measured using the Wilhelmy plate method. The Krafft point was determined using the ultraviolet/visible spectrophotometer. The effect of pH on the solute in the solution was studied using potentiometric titration. The critical packing parameter (CPP) and Gibbs free energy (ΔG) of micelle formation were calculated using the corresponding parameters. The temperature-concentration phase diagram of sodium lauryl glutamate was constructed using the dynamic light scattering system (DLS) and polarised optical microscopy (POM). The calculated theoretical data were combined with the actual observed data from the phase diagram. Finally, the phase behaviour of sodium lauryl glutamate was determined.
