More Information
Summary:Lipase-catalyzed transesterification reactions yield novel ferulyl-substituted or coumaryl-substituted acylglycerols with properties suitable for use as sunscreen agents having broad spectrum UV protection. These agents have the advantage of being synthesized from natural materials, while providing a value-added use for vegetable oils. They are readily incorporated into standard sunscreen formulations. Selon l'invention, des réactions de transestérification catalysées par lipase permettent de produire de nouveaux acylglycérols à substitution ferulyle ou coumaryle présentant des propriétés leur permettant d'être employés comme écrans solaires ayant un large spectre de protection contre les UV. Ces agents présentent l'avantage d'être synthétisés à partir de matières naturelles, et permettent une utilisation à valeur ajoutée d'huiles végétales. Lesdits agents peuvent être intégrés directement dans des formulations de protection solaire standard.
