1. A method for preparing a composition of diesters comprising at least one addition reaction of an acid functional group of at least one saturated fatty acid containing from 2 to 18 carbon atoms on a carbon-carbon double bond of at least one unsaturated compound selected from among an unsaturated alcohol containing from 11 to 20 carbon atoms, an ester of a saturated fatty acid containing from 2 to 18 carbon atoms and of an unsaturated alcohol containing from 11 to 20 carbon atoms, or a mixture thereof, in the presence of at least one acid catalyst, wherein the unsaturated alcohol or the ester thereof is derived from plant or animal oils.
