They are the basis of cosmetic formulations, ensuring their textures, their functionalities, their effectiveness… But lipids today are also synonymous with new challenges, for manufacturers and research, because of consumer and environmental concerns that threaten the sector. During the Lipids & Cosmetics congress, organized by Cosmetic Valley and Iterg on 29 and 30 January in Bordeaux, Professor Michel Grisel, from the Organic and Macromolecular Chemistry Research Unit of Le Havre, presented a panorama of the world of lipids and their current issues.
