“…Early emulsion systems were studied in the 1980s where it was determined that ''emulsols'' [13] were formed utilizing a medium viscosity mineral base oil, a sulfonate type emulsifier, and any required extreme pressure and anti-wear additives.

Oil in water emulsions of several vegetable oils were studied in order to prepare a useful lubrication fluid. Several previously uncharacterized systems were studied in this paper, including those made from epoxidized vegetable oils. A series of different surfactants were studied in order to obtain emulsions suitable for lubrication applications. The epoxidized oils were found to form stable oil in water emulsions using several different surfactant systems. Only the (4) lauryl ether dodecyl polyethoxylated nonionic surfactant and a modified palm stearin methoxy ester ethoxylate were able to stabilize ordinary soybean oil for 1 week under our test conditions. Overall, the best surfactants were those with an HLB value slightly above 9. The droplet size of emulsions made with surfactants formed submicron droplets, whereas only droplets of larger diameter were obtained when surfactants were not added. Most importantly, a lubrication study was performed showing that even a 1% emulsion of the vegetable oils used in this study can reduce friction nearly as well as using the base oil alone.
