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.

Use of oils comprising non-neurotoxic anti-wear additives

The use of an additive including a mixture of oligomers that is produced from the reaction of aromatic amines chosen from: (i) the reaction with one another of diphenylamine (DPA) compounds of formula (I) below: wherein the groups Rand Rstand for, independently of one another, a hydrogen or a linear or branched alkyl group having from 1 to 30 carbon atoms, advantageously from 4 to 12 carbon atoms, (ii) the reaction with one another of phenyl-&#x3b1;-naphthylamine (PAN) compounds of formula (II) below:  wherein the group Rstands for a hydrogen or a linear or branched alkyl group having from 1 to 30 carbon atoms, advantageously from 4 to 12 carbon atoms, and (iii) the reaction of a (DPA) compound of formula (I) above with a (PAN) compound of formula (II) above as an agent for the stabilization of a lubricating composition for a conveyor chain subjected to a temperature of at least 120&#xb0; C.
