Certain embodiments of the invention provide a lubricating oil composition comprising a lubricating oil base stock and a compound of formula (I):

##STR00001##

or a salt thereof, wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 have any of the values defined in the specification, as well as methods of use thereof.

Household lubricant compositions containing medium chain triglycerides are non-toxic and biodegradable. The lubricant compositions are made using vegetable oil components and stabilized using alcohol, an antioxidant, and a metal chelator. The lubricant compositions offer safe and environmentally friendly alternatives to petroleum-based lubricants, yet have similar lubricity and are more stable than naturally sourced vegetable oils. The compositions also can be used to clean and coat surfaces, including food preparation surfaces, and to prevent corrosion. Still further uses include sterilization and sanitation of surfaces and as a skin conditioner and lubricant.

The present invention describes a water based semi-synthetic metal working fluid comprising a base oil, an organic acid, emulsifiers, a concentrate additive, water and a microbial growth control agent which comprises an alky alcohol amine.

The present invention relates to the use of a lubricating composition for lubricating gear, wherein the lubricating composition comprises: at least a base oil; and at least a Molybdenum or Tungsten chalcogenide nanoobject having an object size ranging from 0.1 to 500 nm and from 1 to 99% by weight of molecules of formula (I) with respect to the total weight of the nanoobject
A-X-B(I).

The current invention relates to a novel class of alkyl alcohol amines where the amine is a primary amine. Embodiments relate to a method of controlling microbial growth in metal working fluids, comprising adding such an alkyl alcohol amine to the metal working fluid. Other embodiments relate to semi-synthetic metal working fluid compositions which include the microbial growth control agent comprising this particular class of alkyl alcohol amines.

The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and friction modifiers that contain one or more amide functional groups, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.

Stable, solid triamine compositions are disclosed. The pressed, cast, extruded or other solid compositions are suitable for antimicrobial, sanitizing and disinfectant applications. Ready-to-use solutions are obtained by dissolving the solid triamine compositions with water and the methods of use thereof are particularly suitable for cleaning, disinfecting, sanitizing, rinsing and/or lubricating. Beneficially, the solid triamine compositions are at least partially neutralized, allowing activity of 90% and greater of the biocidal triamine, and provide at least substantially similar or superior performance and micro efficacy to liquid formulations.

The invention provides a method of lubricating a mechanical device by supplying a lubricating composition containing an oil of lubricating viscosity and a compound having 2 to 20 hydroxy-carboxylic acid residues. The invention further relates to the use of the compound in a driveline device to provide at least one of antiwear performance, friction modification (particularly for enhancing fuel economy).

The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and friction modifiers derived from hydroxy-carboxylic acids, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.

A food grade lubricant composition includes an emulsion having 85%-95% w/w water, 1%-4% w/w polyalphaolefin 4, 1%-4% w/w sorbitan monolaurate, 2%-5% w/w polyoxyethylene 20 sorbitan monolaurate, and a food grade preservative.
