Mahonial
Mahonial is a synthetic floral molecule by Givaudan (its chemical name is (4E)-9-hydroxy-5,9-dimethyl-4-decenal), developed as a replacement for the mild floral ingredient lilial. Lilial was classified as a fragrance allergen as of 1 March 2022 and has thus been banned in the EU due to a possible link to infertility in animals in studies.
