The Group is committed to continuous improvement in terms of environmental and societal impact by 2030. Within this framework, in the Physicochemistry Group of the Science and Formulation Processes Invention Domain, we are exploring new combinations of biosourced ingredients to offer new high-performance products that address these challenges. To achieve this, we rely on a rigorous scientific approach focused on understanding the structure-property-performance relationships involved in achieving the key benefits of different cosmetic product categories. This understanding involves studying the relationships between the Raw Materials of interest, the microstructure of the formulas containing them, from the jar to the application on skin, and the properties evaluated in vitro, based on physico-chemical observations and characterizations at different scales.
