We investigated the dynamical behavior between the redox potential and the viscosity and density of the Belousov-Zhabotinsky (BZ) reaction by the systematic variation of the mixing level and the solution viscosity and density. The mixing level was controlled by the stirrer bar speed, and the solution viscosity and density was changed by the addition of polyoxyethylene (10) octylphenyl ether (Triton X-100). This study has revealed that three types of oscillations with phase difference appear, depending on the mixing level and the solution viscosity and density of the BZ reaction. It has also become clear that the critical micellization concentration (cmc) plays an important role in the behavior of the oscillation of the solution viscosity and density.
