The conductivity of different ME was found tobe in range 137.0 ± 2.3 s cm−1to 194.5 ± 2.8 s cm−1. This resultsshows the microemulsions were O/W type. The refractive index ofall ME was ranged between1.35 and 1.40 signifies that preparedME were clear and transparent. Poly dispersity index is a mea-sure of particle homogeneity and it varies from 0.145 ± 0.006 to0.349 ± 0.014 (Table 2)
