In this paper, temperature dependent phase behavior of pseudo-ternary Triton X-100+1-hexanol (1:5 molar ratios)/ oil/ water systems is reported. The influence of nature of hydrocarbon oil and type of electrolytes (weak as well as strong) has been investigated on the temperature induced phase behavior of the ternary system. At surfactant concentration, f_s = 40%, a "nose-shaped" microemulsion region is observed. Below one-phase microemulsion region, Lá phase appears. The presence of NaCl and oxalic acid has opposite effect on the domain size of the micellar region. The presence of NaCl decreases the domain size of 1f micellar region whereas oxalic acid first decreases the domain below f_w<18 and then increases above f_w >18 in the lower boundary of the phase diagram. The critical weight fraction of water, f_w^cri decreases in presence of both electrolytes. However, f_w ^max increases in presence of oxalic acid and remains constant in presence of NaCl as compared to salt free system. Furthermore, when cyclohexane was replaced by a longer straight chain hydrocarbon, dodecane, the domain of the one-phase microemulsion region is tremendously increased.
