Abstract
A method of producing a nanoemulsion is disclosed that provides an oleaginous base fuel, and water in an amount of at least 10 wt %. A first nonionic surfactant, a second nonionic surfactant and a third nonionic surfactant are mixed in substantially equal weight ratios into a surfactant mixture. The surfactant mixture is mixed with the water and the base fuel to form the nanoemulsion fuel. A nanoemulsion fuel composition can comprise an external oleaginous phase comprised of base fuel, an internal aqueous phase comprised of water, and a surfactant mixture comprised of a plurality of surfactants. The first surfactant can be derived from ethylene oxide, the second surfactant and the third surfactant are detergents having a fatty acid.
