  • Worth watching Fragrance/Parfum“Parfum” stands for a mixture whose composition does not have to be detailed. Some allergenic substances must nevertheless be named separately in the ingredient list above 0.001% (leave-on product) or 0.01% (rinse-off product). The Regulation names them in 63 entries of its Annex III, for example Linalool, Limonene, Citronellol, Geraniol, Coumarin, Citral, Eugenol or Hexyl Cinnamal: if you are allergic to one of them, look for its name in the list.
