The invention relates to lubricating greases based on alkali metal soaps and/or earth-alkali metal soaps and metal complex soaps based on (R)-10-hydroxyoctadecanoic acid and to the use thereof.

The invention relates to lubricating greases based on alkali metal soaps and/or earth-alkali metal soaps and metal complex soaps based on (R)-10-hydroxyoctadecanoic acid and to the use thereof.

The present invention relates to a grease composition including: a base oil; a thickener; a rust inhibitor; and an extreme pressure agent, in which the rust inhibitor includes, with respect to a total mass of the grease composition: 0.10 mass % to 10.00 mass % of a calcium sulfonate; 0.20 mass % to 10.00 mass % of a zinc sulfonate; and 0.10 mass % to 10.00 mass % of a zinc carboxylate, and the extreme pressure agent includes, with respect to the total mass of the grease composition, 2.00 mass % to 14.00 mass % of a zinc dialkyldithiophosphate.

Lubricant compositions comprising a base oil, one or more antioxidants selected from a group consisting of N-α-naphthyl-N-phenylamine antioxidants and diphenylamine antioxidants; and a sulfur-containing additive comprising up to seven carbon atoms exhibit outstanding oxidative stability and non-corrosion properties. The N-α-naphthyl-N-phenylamine antioxidants plus diphenylamine antioxidants in total may be present from about 0.2 wt % to about 0.8 wt %, based on the total weight of the lubricant composition. The sulfur provided by the sulfur-containing additive may be present from about 50 ppm to about 1000 ppm by weight, based on the total weight of the lubricant composition.

A universal additive for fuel and lubricants contains C2-C4 alcohols, carbamide, boric acid, acrylic compounds, and water. The additive allows for more complete combustion of liquid and solid fuels, as well as reduced fuel consumption and fewer harmful emissions. In lubricating oil compositions, the additive reduces wear on the friction surfaces of engines, and also reduces fuel consumption.

Provided is a low sulfated ash engine oil lubricant composition containing organic friction modifiers with improved fuel economy and corrosion resistance. The lubricant composition includes one or more metal free corrosion inhibitors having an organic acid group and/or one or more organo metallic naphthalene molecules having a ASTM D2896 total base number less than 3 mg KOH/g. The resulting lubricant composition improves ASTM D6557 corrosion protection for low sulfated ash engine oils containing organic friction modifiers, while maintaining exceptional fuel economy performance.

A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.

A phosphonium-based ionic liquid compound including a particular phosphonium cation and a carboxylate anion. A lubricant composition including it, and its use as a detergent and anti-corrosion additive in a lubricant, in particular a marine lubricant.
