Table . Interfacial Tensions of various liquids against 0.6 M salt aqueous solution with and without the addition of surfactants measured by Du-Nouy ring method. From these dynamic viscosity values, it is concluded that there is no significant change in the viscosities of the liquids with the addition of hydrophobic polymers to the oil. was connected to a polyvinyl stopper and a needle assembly, through which the liquid sample from inside the conical flask was siphoned out drop by drop a collected at a rate of ~1 mL/min. After making sure that the Teflon tube was fully filled with the aqueous phase, and the disturbance of the surface subsided, 30 mL of oil (with/without additive) was gently poured over it. Before collecting the emulsion, some amount of the salinized water that pre-filled the tube was discarded, following which, the samples were collected at pre-set intervals.
