Abstract
The invention concerns a method for preparing a lactic acid ester composition based on a lactic acid composition involving a step of transforming the composition into a lactic acid oligomeric composition having a mean degree of polymerisation (DPM) ranging between 2 and 30 approximately; and a step which involves mixing and reacting said oligomeric composition with an alcohol, in the presence of a transesterification catalyst, to esterify all or part of the lactic acid contained in said oligomeric composition. The invention also concerns the use of ethyl lactate as solvent for preparing gelified compositions.
