Abstract

A method of evaluating a surfactant is provided. The method includes preparing a first emulsion comprising an aqueous phase, an oleaginous phase, and a first surfactant. Then the method includes determining an average droplet size of oleaginous phase droplets in the first emulsion. The method then includes preparing a second emulsion comprising the aqueous phase, the oleaginous phase, and a second surfactant, and then determining an average droplet size of oleaginous phase droplets in the second emulsion. After determining droplet sizes of both emulsions, the method includes comparing the average droplet size of the of the oleaginous phase droplets in the first emulsion to the average droplet size of the oleaginous phase droplets in the second emulsion, and based on the comparing of the average droplet sizes, determining a relative interfacial tension of the first surfactant as compared to the second surfactant.
