ABSTRACT

Influence of bivalent malate counterion on physicochemical properties of butanediyl-1,4-bis(hexadecyl hyhdroxyethyl methyl ammonium bromide) surfactant was studied by conductometry measurement. Critical micelle concentration, average degree of micelle ionization, kraft temperature and gibbs free energy of micellization were determined from conductivity data. Oil solubilization and foamability was observed to increase at 1:0.5 surfactant to counterion charge ratio. The decrease in change in gibbs free energy and foam stability indicate that the micellization process was retards at theoretical unequal surfactant to counterion charge ratio(1:05).

Keywords: Surfactant, counterion, kraft temperature, cmc, oil solubilization.
