The nonaqueous system of molten salts, sodium dodecyl sulfate (SDS), 1-pentanol, and decane is studied with electrical conductivity measurements in the molten salt rich emulsion phase. The molten salts are a nitrate mixture of ethylenediamine/ammonia/potassium in a ratio of 50/42.5/7.5 by weight. The addition of alcohol to a fixed ratio of salts/surfactant/oil initially causes the conductivity to decrease and then to increase; the solution also exhibits a change from turbid to clear to increasing turbidity. This may indicate a structural change from a globular droplet to a bicontinuous lamellar form. Other properties related to these measurements will be discussed in terms of microemulsion.
