The phase diagrams of pseudoternary mixtures Tween80–butanol–kerosene–water system were constructed by visual titration. major three domains, i.e., oil in water, bicontinuous, and water microemulsions demarcated through conductivity measurement. A sharp increase specific conductance increasing content the bicontinuous domain has been ascribed to percolation ions continuum. Temperature induced clouding behavior Winsor IV domains was investigated find out effect composition on temperature. generalized regression model proposed considering cloud point be a function surfactant/cosurfactant ratio emulsifier contents. all these parameters increases points mixture. In turbid III domain, temperature an emulsifying effect. With temperature, separates different phases, which experience transparent, translucent, characteristics due mass transfer from one another. phenomenon well visualized using nickel as water-soluble N-alkyl 4-(p-N,N-dimethylaminostyryl)pyridinium dyes oil-soluble probes.
