Summary, etc. The interactions between the reactive cationic surfactant, <em>N</em>-tetradecyl-<em>N</em>,<em>N</em>-dimethyl-<em>N</em>-(2,3-epoxy propyl) ammonium chloride (TDEAC) and common surfactants, i.e., sodium dodecyl sulfate (SDS) sodium dodecyl sulfonate (AS), dodecyltrimethylammonium chloride (DTAC) and <em>N</em>, <em>N</em>-dimethyldodecylamine oxide (C<sub>12</sub>DMAO) are studied through surface tension, conductivity, steady-state fluorescence and dynamic light scattering as well as Rubingh regular solution methods. The calculated values of cmc, <em>γ</em><sub>cmc</sub>, <em>p</em>c<sub>20</sub>, <em>π</em><sub>cmc</sub>, <em>Г</em><sub>max</sub>, and <em>A</em><sub>min</sub> indicate a strong synergistic effect between TDEAC and SDS (and AS) as compared with the relatively weak interaction of TDEAC with DTAC (and C<sub>12</sub>DMAO). The cmcs of the mixed surfactant systems vary with temperature. Thermodynamic parameters calculated from conductivity data show that the micellization of TDEAC/SDS (AS) mixed systems is a spontaneous and exothermic process. Data from steady-state fluorescence, dynamic light scattering and Rubingh’s regular solution approach, confirm the strong interaction between surfactants.
