SOLUTION AND FOAMING PROPERTIES OF MIXED AQUEOUS-SOLUTION OF CTAB-TRITON X-100

The critical micelle concentrations (CMC) of mixed aqueous solution of cationic surfactant cetyltrimthylammonium bromide (CTAB) and nonionic surfactant polyoxyethylene t-octylphenol (Triton X-100/TX 100) have b een determined conductometrically at 35, 40, 45 and 50 degrees C. The mixtures used are of various composition ratios of CTAB and TX 100. Th e degree of ionization (proportional to) of the mixed micelle has been computed from the slope of conductance versus concentration (C) plot above and below CMC. Foaming efficiency and viscosity of mixed surfact ants have been measured at 45 degrees C. Wetting property of the above systems has also been studied. The concentration of TX 100 is kept co nstant and that of CTAB changed.
