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.

The invention relates to compositions including esters of polyvalent alcohols that are esterified with fatty acids, partially unsaturated, from plant oils, and to the use thereof as cooling and insulating fluids for transformers.

Provided herein are estolide compositions having high oxidative stability, said compositions comprising at least one 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 1; 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 herein are uses for the compositions and methods of preparing the same.

A composition of an oil-soluble ionic detergent that does not contribute metal ions to the composition, and which comprises a quaternary non-metallic pnictogen cation and an organic anion having at least one hydrocarbyl group of sufficient length to impart oil solubility to the detergent, the detergent having a total base number (TBN) to total acid number (TAN) ratio of at least 2:1 imparts ash-free basicity to a lubricant composition.

Lubricating oil composition is provided. The composition includes several components including a major amount of a base oil, a mixture of alkylated diphenylamines having a weight ratio of mono-alkylated diphenylamine to di-alkylated diphenylamine ranging from 0.6 to 4.0, and a molybdenum or sulfur additive that provides synergistic enhancement of oxidation stability in combination with the mixture of alkylated diphenylamines.
