Technical Abstract: Vegetable oils are obtained from abundantly available and renewable agricultural products. They are also biodegradable and safe to use. These properties make vegetable oils the preferred raw materials over petroleum-based oils for the manufacture of various consumer and industrial products. Vegetable oils are widely applied in the development of lubricants, printing inks, cosmetics, soaps, and surfactants. In this work, soybean oil was used to synthesize a series of polysoaps. The surface properties of these polysoaps were investigated as a function of their chemical structure. The surface properties that were investigated include: dynamic and equilibrium surface tension of water, and oil/water interfacial tension. The effects of molecular weight and counter ion on these surface properties are discussed.
