The INTICOSM project aims at the cross-border development of biosourced compounds and their use in the field of cosmetic formulation. These compounds, known as green cargo ships, will preferably be produced from biosourced molecules primarily from biorefineries in the Franco-Belgian region (in particular the Pomacle-Bazancourt biorefinery near Reims, the largest in Europe and BioWanze in Wallonia, the largest producer of bio-ethanol in Belgium), while respecting as much as possible the principles of green chemistry, in particular by reducing the use of solvents and the number of synthesis steps. It will be considered to prepare cargo ships that can selectively release cosmetics depending on the medium or temperature. Regulatory constraints and costs will be taken into account to ensure their competitiveness in relation to existing petroleum compounds. This part will be carried out in France (URCA) and Flanders (UGent).
