The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.

A lubricating fluid suitable for use as a shock absorber fluid is disclosed. The lubricating fluid comprises at least 40 wt %, based upon the weight of the lubricating fluid, of a GTL base oil, has a viscosity index in the range of from 50 to 1000, and a pour point of below 30 C.

A fabrication fluid composition, such as a metal cutting fluid concentrate, contains water, a first surfactant which is an anionic surfactant, a second surfactant which is an amphoteric surfactant, a third surfactant which is selected from an anionic surfactant and an amphoteric surfactant, the third surfactant being different from the first and second surfactants, and water, along with at least one of an anti-rust agent, a coloring agent, and a de-foaming agent. The concentrate may be combined with water to provide a fabrication fluid such as a metal cutting fluid composition that may be applied to a piece of metal being cut for a time and in an amount effective to dissipate heat from the metal being cut.

The invention relates to the use of an alcohol of formula ROH (I), in which R is a linear or branched saturated alkyl group with 10 to 36 carbon atoms, in a lubricant composition to improve the cleanliness of a 4-stroke vehicle engine.

It is to provide a lubricating oil composition for a compression refrigerator, which is excellent in the thermal/chemical stability even when used in a compression refrigerator that uses a saturated fluorinated hydrocarbon refrigerant having a lower global warming potential and a fewer carbon atoms, by including in a base oil an organic compound having a double bond in a molecule, which is at least one kind selected from an organic compound having at least two non-conjugated double bonds in the molecule, a terpene compound having a double bond in the molecule, and C.sub.12 to C.sub.30 aliphatic unsaturated hydrocarbon having one double bond in the molecule.

Traction fluid additive combination that is usable with any traction fluids base stock is provided. To optimize the traction, low temperature viscosity and shear stability performance, a combination of a polyisobutene and a polymethacrylate may be added to a base oil to obtain a traction fluid with good low temperature viscosity without degrading the shear strength properties of the fluid. To minimize foaming of the traction fluid, a combination of one, two, or more anti-foaming agents may be added to the fluid in addition to a standard additive package.

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a tetrafluoropropene and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

A gear lubricant composition includes at least 97% by weight, based on the total weight of the lubricant composition, of at least one hydrocarbon-based oil that includes a weight content of isoparaffins ranging from 90 to 0%, a weight content of normal paraffins ranging from 0 to 10% and a carbon content of biological origin greater than or equal to 90% relative to the total weight of the oil, at least 0.01% by weight, based on the total weight of the lubricant composition, of at least one additive selected among the anti-wear additives, extreme pressure additives, anti-corrosion additives, additives having metal-deactivating properties, anti-foam additives, anti-oxidant additives selected among the phenolic anti-oxidants, and the mixtures thereof.

A defoaming agent obtainable by a process, the process including the step of: (i) polymerizing (B) at least one defoaming agent monomer in (A) a polymerization solvent under coexistence of (C) a polymer soluble in the polymerization solvent.

A lubricating oil composition including: a lubricant base oil; (A) a first defoaming agent obtainable by a process, the process including the step of: polymerizing (b) at least one defoaming agent monomer in (a) a polymerization solvent under coexistence of (c) a polymer soluble in the polymerization solvent; and (B) a second defoaming agent being a silicone defoaming agent.
