The invention relates to liquid compositions for use with hair removal devices comprising a metathesized unsaturated polyol ester for improved lubrication.

The present invention relates to a lubricating composition for an engine, in particular for a motor vehicle engine, comprising at least one base oil and at least one compound able to release formaldehyde under the temperature and pressure conditions of the combustion chamber of the engine. It also relates to the use, in a lubricating composition intended for an engine, of a compound able to release formaldehyde under the temperature and pressure conditions of the combustion chamber of the engine, as an additive for preventing and/or reducing pre-ignition, in particular low-speed pre-ignition (LSPI).

An additive composition for a hydraulic fluid, or a heat transfer fluid, comprises one or more phosphate esters derived from the esterification of phosphoric acid and one or more monomer glycols containing up to 18 carbon atoms, or combinations thereof. In addition, the additive composition may comprise one or more corrosion inhibitors selected from the group consisting of dicarboxylic acids, alkanolamines or combinations thereof; one or more antioxidants including selected from the group consisting of one or more organosulfur compounds, one or inorganic oxyanion salts or combinations thereof; and, one or more surfactants.

A lubricant for a medical device includes an anti-friction material and a radical scavenger.

This invention relates to a liquid antioxidant composition which finds utility as an antioxidant additive in candle wax and lubricant compositions, and has an additional effect of preventing crystallization of the tolutriazole additive used in such compositions. In particular, the antioxidant composition is a combination of an alkylated diphenylamine derivative of tolutriazole with benzyl benzoate.

A solid-state lubricant composition is disclosed. The solid-lubricant contains graphene, an oxide of a metal, and one or more polymeric binders. A method of making a solid-state lubricant coating on various substrates is disclosed. The method includes the steps of making a homogeneous slurry comprising powder of an oxide of a metal, graphene, and a polymeric binder with organic volatile solvent; coating a substrate with the homogeneous slurry with desired thicknesses; and drying the slurry on the substrate naturally or applying additional heat, resulting in a solid lubricant coating on the substrate. Substrates with coated solid composite lubricant show wear reduction and lower coefficient of friction compared with uncoated substrates.
