An organic lubricant composition comprising a vegetable oil; an organic acid; and an organic alcohol, where the organic lubricant composition is substantially free of inorganic compounds.

The present invention relates to conveyor lubricant compositions including an emulsion of a lipophilic compound and also including an emulsifier and/or an anionic surfactant. The present invention also relates to methods employing such lubricant compositions. In an embodiment, the method includes applying the present lubricant composition to a conveyor with a non-energized nozzle.

Lubricant composition formulations comprising at least one biodegradable plastic, such as polyhydroxyalkanoate and/or polybutylene succinate, and at least one lubricant, such as a vegetable oil.

Levulinic-capped estolides having improved physical properties that make them more desirable and suitable as bio-based industrial or commercial products are disclosed. The physical properties of the disclosed estolide compositions have surprisingly low pour points that are substantially lower than previously known estolide compounds and superior to petroleum-based compounds designed for similar applications.

Lubricant composition formulations comprising at least one biodegradable plastic, such as polyhydroxyalkanoate and/or polybutylene succinate, and at least one lubricant, such as a vegetable oil.

Provided is a solid lubricant that is non-black in color and capable of reducing industrial waste (environmental conservation), and further capable of achieving a balance among excellent lubricity, moisture absorption resistance, and corrosion resistance in a heavy working region, and a lubricating coating agent including the solid lubricant.

A solid lubricant including carrier particles including a lipophilic lubricating component that is at least one of an oil, an extreme-pressure agent, a soap, and a wax between particles of and/or between layers of at least one layered clay mineral selected from the group consisting of natural products and synthetic products of a smectite group, a vermiculite group, a mica group, a brittle mica group, a pyrophyllite group, and a kaolinite group.

Provided herein are grease compositions comprising at least one estolide compound of formula: ##STR00001##
in which n is an integer equal to or greater than 0; m is an integer equal to or greater than 2; R.sub.1, independently for each occurrence, is selected from optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; R.sub.2 is selected from hydrogen and optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; and R.sub.3 and R.sub.4, independently for each occurrence, are selected from optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched. Also provided are methods of making estolide-based grease products.

Provided is a water-based lubricating coating agent for a metal material, capable of carrying out a chemical conversion treatment and a lubrication treatment at the same time, which makes it possible to achieve excellent lubricity even in plastic working, press molding, and the like, and at the same time, operability (e.g., process shortening, sludge reduction).

The water-based lubricating coating agent having pH of 2.0 to 6.5 for a metal material is obtained by blending: at least one lubricating component other than black-based solid lubricants; and at least one chemical conversion component selected from the group consisting of a phosphoric acid compound, an oxalic acid compound, a molybdic acid compound, a zirconium compound, and a titanium compound, the concentration of the lubricating component is 5 mass % or more in mass ratio to the total solid content mass in the lubricating coating agent, and the concentration of the chemical conversion component is 0.3 to 8 mass % when the total mass of the lubricating coating agent is regarded as 100 mass %.
