2-OCTANOL MONOESTER AS LUBRICANT
The present invention relates to a lubricating composition comprising: from 0.1% to 30% by weight, with respect to the total weight of the composition, of at least one 2-octanol monoester of formula R1-C(═O)OR2, in which R1 denotes an alkyl group comprising from 8 to 36 carbon atoms and R2 denotes 1-methylheptyl, and at least one base oil. The invention also relates to the use of the 2-octanol monoester as additive in a lubricating composition.
