A surfactant association behaviour, in order to locatea region of water-in-oil (W/O) microemulsion, stabilised by non-ionic surfactants was carried out. The use of pseudoternary phase diagrams to locate the microemulsion region will be described and the compositions of the template will be suggested. The results showed that the W/O microemulsion were located mostly at the surfactant mixtures apex and protruding towards the water-oil axis. The size of the aggregates were also found to be increasing with the increment of water. This suggested that along the line at increasing water various sizes of aggregates are formed and thus maybe selected as templates for the preparation nanomaterials with the desired particle size.
