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.

The present disclosure is directed to a composition and method for producing a nanoemulsion comprising fuel and water. The composition and method can produce a transparent and stable water in fuel nanoemulsion. The disclosure is directed to various surfactants and water contents that may be usable to improve fuel efficiency and reduced carbon emissions that plague known fuels.

There is disclosed an antifoam component which includes at least one acrylamide polymer for use in a diesel fuel. Acrylamide polymers prepared by polymerizing a (meth)acrylamide monomer to yield a homopolymer or, alternatively, the acrylamide polymer may be prepared by polymerizing a (meth)acrylamide monomer and a (meth)acrylate monomer to yield a heteropolymer.

Disclosed are organomodified polysiloxanes, compositions, in particular fuel compositions, that include these organomodified polysiloxanes, and the use of the organomodified polysiloxanes for the defoaming of fuels.
