Summary The effect of some anionic surface active agents has been studied on the stability of the emulsions stabilized by partially flocculated chromium hydroxide sol. The chromium hydroxide sol was prepared, dialysed, partially flocculated and then used for emulsification. The stability of these emulsions has been assessed by the measurement of zeta potentials in presence of anionic surface active agents, where the decrease in zeta was observed. The interaction energies were calculated and plotted as a function ofH. The plots exhibit a high potential energy and hence a high degree of stability. To explain it, the possibility of occurrence of secondary minima has been assumed which was observed at higher distances. The degree of aggregationD was also calculated and the value ofA was observed 0.2×10−12 erg for Cr(OH)3 coated oil droplets. The effect of these surfactants on interfacial tension between the two phases was also studied, a regular decrease was observed, depending on the chain length of the surfactants.
