Lipids (triglycerides and derivatives) are natural compounds, essential in cell membrane structure and metabolism of all living organisms. Their interaction with lipids provided by an external source naturally leads to particular properties. Use of lipids in cosmetics, main constituent of formulations, helps to form a protective barrier on the skin against harmful substances or dangerous stimuli and to maintain good hydration.
Lipids can be integrated into different/various formulations, liquid (emulsions) or solid (powder) form, as a main matrix, active or ingredients (vitamins, tocopherols for example).
To be ever more innovative, needs are emerging, at analytical level, in terms of new sourcing, or for ecofriendly oleochemical derivatives. These elements are more generally part of a process of relationships understanding between structures, formulations and properties.

For this 2022 edition, Cosmetic Valley in partnership with the French Institute of Fats and oils (ITERG), the Agro Resource Valorization Center (CVA), the Bordeaux University and the Région Nouvelle-Aquitaine, proposes four new topics:
• The importance of physiology of lipids in skin and hair - Physiology, External source and interactions
• Lipid treatment to enhanced functionalities for formulation
• New lipid sourcing : valuations, constraints and opportunities - Where to find them and How to get …
