Abstract: Disclosed is the use of specific organophosphorus compounds as anti-wear agents in an oil so as to prevent and/or reduce the neurotoxicity of the oil and/or for the prophylaxis of aerotoxic syndrome in the instance of a fume event.

Abstract: The invention relates to a composition preparation method for preparing a composition of estolides, the method comprising reacting an unsaturated compound of a type such as an acid or ester, with a saturated fatty acid; in the presence of a catalyst of a type such as sulphonic acid, the said method including no vacuum distillation step thereby making it possible to separate the monoestolides from the polyestolides. The invention also relates to a composition of estolides that is obtainable by the method according to the invention and the use thereof in lubricating compositions.

Abstract: The invention relates to the use of an oil that does not include tricresyl phosphate and includes as an anti-wear additive at least one diphosphorus compound for the prophylaxis of aerotoxic syndrome, especially in case of fume event. It also relates to the oil as such.
