An electrotechnical fluid composition, comprising more than 90 wt-% paraffins in the C17-C18 range, based on the total weight of the composition, is described. The ratio of the amount of C18 i-paraffins to the amount of C18 n-paraffins is more than 40, based on the weight of the C18 i-paraffins and the weight of the C18 n-paraffins in the composition.

Disclosed is a method of producing an estolide having high structural stability, including: a) preparing a fatty acid mixture from biomass-derived oil; b) separating the fatty acid mixture into a C16 fatty acid and a C18 fatty acid; c) converting the C18 fatty acid into a C18 or C17 linear internal olefin; and d) subjecting the C18 or C17 linear internal olefin and the C16 fatty acid to an estolide reaction, thus obtaining an estolide.

Described herein are methods of stabilizing the beta hydrogen of glycerol based esters by the insertion of alkoxy groups to significantly improve the thermal, oxidative, and hydrolytic stability of the ester and allow for controlling the molar density of esters bonds in the lubricants to maximize hydrolytic stability while maintaining biodegradability and further improving performance properties.

The present invention relates to a lubricant base stock, lubricant formulations, a method of lubricating a rotating shaft within a stern tube and the use of a lubricant base stock. The base stock and lubricant formulations may be particularly suited for use in aqueous environments (including fresh water or salt water). A lubricant base stock comprising a first (EO)(PO)(EO) block co-polymer and a second (EO)(PO)(EO) block co-polymer which is different from the first (EO)(PO)(EO) block co-polymer in a marine lubricant formulation wherein the lubricant base stock has a density of at least 1028 kg/m.sup.3 at 20° C. and at most 1022 kg/m.sup.3 at 40° C. in particular is provided.

A lubricant composition comprising an oil-soluble polyalkylene glycol; an ester compound selected from the group of natural esters and synthetic esters, and combinations thereof; and an additive mixture comprising an antioxidant and an anticorrosive, wherein the anticorrosive is selected from neutral alkali metal and alkaline earth metal salts of sulfonic acids, carboxylic acids, naphthoic acids, naphthenic acids, benzoic acids and phosphoric acids, and derivatives and combinations thereof.

A water-based lubricating grease composition includes at least 40 wt % water; a salt-based thickener; a polymer-based thickener; and optionally, an inorganic solid-based thickener. A process for preparing the water-based lubricating grease composition may include blending a suitable amount of water with a salt-based thickener to provide a thickened water-based grease, wherein the salt-based thickener is obtained from contacting a base with a fat; and adding a polymer-based thickener to the thickened water-based grease.

A composition for an aqueous tacky lubricant, specifically targeted towards increasing lubricant retention to the moving components of chainsaws. More specifically, the composition includes a novel additive composition for environmentally-neutral lubricants. The ideal function of the composition would be to increase the adhesive qualities of an aqueous lubricant without compromising the coolant and lubricant roles of such a substance. To accomplish this, the composition includes an additive compound, that is made of a linear anionic polyamide and a cationic surfactant. The reaction between the linear anionic polyamide and the cationic surfactant creates a viscoelastic tackifier that helps the lubricant to cling to a moving chain thus preventing the lubricant from flinging off the chain when in motion. In other words, the additive compound is a tackifier agent, presented as novel both as an independent composition and in addition to extant lubricants.

An engine oil comprising a biobased hydrocarbon base oil.

The present technology includes an extreme pressure additive package formulated with a biodegradable sulfur component, which additive package can achieve suitable extreme pressure performance when formulated into a fully formulated industrial gear oil lubricant.

The present invention relates to esters of at least one polyol and of a mixture of fatty acids comprising at least one C.sub.5-C.sub.12 saturated fatty acid and at least one C.sub.10-C.sub.12 unsaturated fatty acid.
