The invention relates to the use of an O/W emulsion, in particular a PIT emulsion, for lubricating conveyor belt systems in food industries as well as a lubricant concentrate based on an O/W emulsion, in particular a PIT emulsion, of wax esters.

Turbine lubricant additives and lubricants including such additives that provide rust prevention and water separation but also pass the demanding stage II wet filterability at the same time.

To provide a lubricating oil composition achieving both of high traction coefficient and excellent low temperature fluidity at a higher level and having a high flash point, which contains a naphthene-based synthetic oil (A) having a flash point of 140° C. or higher, a longifolene (B), and a predetermined monoester-based synthetic oil (C), a method for producing the lubricating oil composition, and a continuously variable transmission using the lubricating oil composition.

[Problem] To provide an aqueous coating agent composition (in particular, an aqueous coating composition for lubricating films that contains a solid lubricant) which as a whole is excellent in terms of flowability, applicability, and storage stability and which is capable of forming satisfactory and smooth coating films effective in stick-slip inhibition. [Solution] The problem can be solved with an aqueous coating agent composition which comprises (A) a curable resin in an aqueous emulsion form, (B) a surfactant, (C) solid particles, (D) one or more nitrogenous heterocyclic compounds, (E) a film-forming silicone in an aqueous emulsion form, and (F) water. In particular, it is preferable that the (C) component comprise a solid lubricant. In view of the environmental regulations, it is especially preferable that the (D) component be 1,3-dimethyl-2-imidazolidinone.

Implementations of wax ester compositions may include: a product of transesterifying oleyl oleate, stearyl stearate, and behenyl behenate using one of a chemical or an enzyme catalyst. The ratio of the oleyl oleate to stearyl stearate to behenyl behenate in the mixture prior to transesterification is one of 65%/23%/12%, 56%/29%/15%, or 36%/34%/30%, respectively, measured by weight. The product may demonstrate a substantially equivalent physical property to a physical property of a transesterified wax ester composition including a jojoba ester.

One or more embodiments presently described are directed to lubricants and methods for making such lubricants. According to one embodiment, a lubricant suitable for use in a water-based drilling fluid may comprise one or more alkyl esters and a fatty acid blend comprising at least palmitic acid and stearic acid. The sum of the weight percent of the palmitic acid and stearic acid may be at least 50 wt. % of the fatty acid blend. The weight ratio of the one or more alkyl esters to the fatty acid blend may be from 1:1 to 3:1. The molar ratio of palmitic acid to stearic acid may be from 20:80 to 40:60.

A magnetic recording medium that can exhibit good traveling performance during use is provided. This magnetic recording medium is a tape-shaped magnetic recording medium, and includes a substrate including a polyester as a main component, a base layer disposed on the substrate, and a magnetic layer disposed on the base layer. The kurtosis of the surface of the magnetic layer is 3.0 or more. The base layer and the magnetic layer each include a lubricant including a fatty acid and a fatty acid ester. In the lubricant, a ratio of the content of the fatty acid to the content of the fatty acid ester is less than 0.6.

The invention relates to rice bran wax oxidates that have optionally been derivatized and to micronized wax additives (MWAs) comprising optionally derivatized rice bran wax oxidate, having a volume-average particle size d.sub.50 of between 1 and 50 μm, and to the production thereof and use thereof in printing inks, paints and coatings.

The present invention relates to the use of a lubricating composition comprising: —at least one base oil; and—at least one monoester which is separate from the base oil and formed between a linear, saturated or unsaturated C.sub.8-C.sub.14 monocarboxylic acid, and a branched, saturated or unsaturated C.sub.4-C.sub.16 monoalcohol to reduce the fuel consumption of a vehicle fitted with a transmission member, in particular a gearbox and/or an axle, which is lubricated by means of said composition.
