The purpose of this study is to examine properties of shear viscosity for surfactant solutions including organic additives. The measurement of shear property was performed with a cone-plate type of rheometer. The surfactant solution used for this experiment is a CTAB/NaSal solution having a ratio of concentration 1/7.7, and the organic additive is an isooctane(2,2,4-Trimethylpentane). In the measurement of dynamic viscoelasticity, the property of relaxation time depends on the concentration of additives. At the concentration of isooctane below 0.1 wt%, this result suggested that the micelle structure changed because of the solubilization of isooctane in the deep interior of micelle. However, when the concentration of isooctane increases further, it is deduced that the micelle structure becomes a different type from that of low concentrations.
