The viscosity, specific viscosity, and fluidity of Cu (II) surfactant derived from karanj oil in non-polar and polar solvent mixture have been determined at constant temperature 303.15 K. The results were used to determine the critical micelle concentration (CMC), solute-solvent interactions and the effect of chain length of the surfactant molecule on different parameters. The conclusions have been discussed in terms of well-known Moulik’s and Jones- Dole equations. The effect of surfactant concentration on viscosity of the solution in solvent mixtures with different polarityhas been discussed. The observations suggested that the structure breaking effect by the solute on the solvent molecules is more prominent above CMC as compared to below CMC after the formation of the micelles. These study helps in interpretation of solute solvent interactions, structural insight of micelle and colloidal chemical behavior in binary/ternary systems. Study of these factors is essential as it indirectly makes them responsible for their immense applicability in wide areas of field. The vital information plays an important role for the selection of the synthesized bio-molecule in various research and development fields.
