A method for manufacturing an oil that is able to and/or configured to lubricate a machine and/or a device, said method comprising the following steps:
- incorporating into a base oil, at least one compound of formula (I)
- wherein A is a linear or branched alkyl group comprising 10 to 32 carbon atoms, and each of Ar1 and Ar2 is independently an aryl group as an anti-wear agent,
- wherein the at least one compound of formula (I) has a risk level in terms of neurotoxicity corresponding to a score of 0 or to a score of 1 and is capable of and/or is configured to reduce and/or prevent the neurotoxicity of said oil.
A method for lubricating a machine and/or a device for reducing the neurotoxicity of an oil, comprising the following steps:
- providing the oil comprising at least one anti-wear agent selected from a compound of formula (I):
- wherein A is a linear or branched alkyl group comprising 10 to 32 carbon atoms, and each of Ar1 and Ar2 is independently an aryl group,
- applying an effective amount of said oil to said machine and/or device,
- wherein the at least one compound of formula (I) has a risk level in terms of neurotoxicity corresponding to a score of 0 or to a score of 1 and is capable of and/or is configured to reduce and/or prevent the neurotoxicity of said oil.
