Abstract In this study, nano-emulsions were prepared using 19.2 wt% n-Dodecane (C12H26) and n-Decane (C10H22) oils as the dispersed phases, 4 wt% Brij 30 (C12E4) as surfactant and 76.8 wt% ultrapure water as the aqueous phase by phase inversion temperature (PIT) method. PIT points were determined by measuring the conductivity of the mixture as a function of temperature. The stability of nano-emulsions was determined by measuring the mean size, polydispersity index (PDI) and size distribution of droplets using dynamic light scattering (DLS) technique and monitoring them as a function of time. The nano-emulsions were also characterised using refractive index (RI), surface tension and pH measurements. The efficiency of reversibility test was also investigated on systems aged for various durations (i.e. 3, 4, 5, 9 and 470 days).
