Abstract

A subject of the present invention is an anti-corrosive and antistatic lubricating composition for a hydrocarbonated mixture comprising: a) at least a compound A of Formula (I) below: ##STR00001## in which R.sub.1 and R.sub.2 are hydrogen or a linear or branched alkyl group of 1-40 carbon atoms, comprising possibly one to five double bond(s), R.sub.1 and R.sub.2 together being able to form an aromatic or aliphatic ring of 5-6 carbon atoms, said ring being capable of substitution by one to three linear or branched alkyl group(s) of 1-40 carbon atoms, in which R.sub.1 and R.sub.2 cannot be hydrogen at the same time, and in which R.sub.3 and R.sub.4, identical or different, are chosen from the OH groups, in which R.sub.3 and R.sub.4 cannot be the OH group at the same time, or deriving from a linear or branched monol or polyol group containing 1-20 carbon atoms having a functionality of 2 to 5 inclusive; b) and at least one B compound corresponding to a fatty acid of 16-24 carbon atoms, unsaturated or not, optionally in a mixture with a carboxylic acid comprising at least one aromatic and/or olefinic polycycle or ring and/or their ester, amide or corresponding amine salts derivatives, taken alone or in a mixture.
