A wear and/or friction reducing additive for a lubricating fluid in which the additive is a combination of a moderately hydrophilic single-phase compound and an anti-wear and/or anti-friction aqueous salt solution. The aqueous salt solution produces a coating on boundary layer surfaces. The lubricating fluid can be an emulsion-free hydrophobic oil, hydraulic fluid, antifreeze, or water. Preferably, the moderately hydrophilic single-phase compound is sulfonated castor oil and the aqueous salt solution additionally contains boric acid and zinc oxide. The emulsions produced by the aqueous salt solutions, the moderately hydrophilic single-phase compounds, or the combination thereof provide targeted boundary layer organizers that significantly enhance the anti-wear and/or anti-friction properties of the base lubricant by decreasing wear and/or friction of sliding and/or rolling surfaces at boundary layers.

A lubricating fluid, comprising: a) a hydrophobic oil;b) one or more single-phase compounds wherein said single-phase compound comprises one or more imidazolium-based ionic liquids; andc) an anti-wear and/or anti-friction aqueous salt solution, wherein said salts in said aqueous salt solution are inorganic salts, and wherein the combination of said one or more single-phase compounds and said aqueous salt solution form an emulsion in said hydrophobic oil. 2. A lubricating fluid, comprising: a) a hydrophobic oil;b) one or more single-phase compounds, wherein said single-phase compound is selected from the group consisting of castor oil, sulfonated castor oil, ethoxylated castor oil, lanolin, triethylamine, 1-octyl-3-methylimidazoliumbis-(trifluoromethylsulfonyl)imide, 1-dodecyl-3-methyl-imidazoliumbis-(trifluoromethylsulfonyl)imide, and 1-butyl-3-methylimidazolium-bis(trifluoromethylsulfonyl)imide, or combinations thereof and wherein a single-phase compound comprises one or more imidazolium-based ionic liquids; andc) an anti-wear and/or anti-friction aqueous salt solution, wherein said salts in said aqueous salt solution are inorganic salts, wherein the combination of said one or more single-phase compounds and said aqueous salt solution form an emulsion in said hydrophobic oil, and wherein said one or more single-phase compounds and said aqueous salt solution are combined in a ratio of 1 part to 2 parts by volume or 2 parts to 1 part by volume or in a ratio therebetween. 3. A lubricating fluid, comprising: a) a hydrophobic oil, wherein said hydrophobic oil forms greater than 20% of said lubricating fluid by volume;b) one or more single-phase compounds wherein said single-phase compound comprises one or more imidazolium-based ionic liquids; andc) an anti-wear and/or anti-friction aqueous salt solution, wherein said salts in said aqueous salt solution are inorganic salts, and wherein the combination of said one or more single-phase compounds and said aqueous salt solution form an emulsion in said hydrophobic oil. 4. A lubricating fluid, comprising: a) a hydrophobic oil, wherein said hydrophobic oil forms greater than 20% of said lubricating fluid by volume;b) one or more single-phase compounds, wherein said single-phase compound is selected from the group consisting of castor oil, sulfonated castor oil, ethoxylated castor oil, lanolin, triethylamine, 1-octyl-3-methylimidazoliumbis-(trifluoromethylsulfonyl)imide, 1-dodecyl-3-methyl-imidazoliumbis-(trifluoromethylsulfonyl)imide, and 1-butyl-3-methylimidazolium-bis(trifluoromethylsulfonyl)imide, or combinations thereof wherein a single-phase compound comprises one or more imidazolium-based ionic liquids; andc) an anti-wear and/or anti-friction aqueous salt solution, wherein said salts in said aqueous salt solution are inorganic salts, wherein the combination of said one or more single-phase compounds and said aqueous salt solution form a stable emulsion in said hydrophobic oil, and wherein said one or more single-phase compounds and said aqueous salt solution are combined in a ratio of 1 part to 2 parts by volume or 2 parts to 1 part by volume or in a ratio therebetween.
