Perfumery is an art made up of a wide and varied palette. It combines natural raw ingredients (essential oils, flower absolutes, citrus fruits, woods, etc.) and synthetic substances. The latter are molecules obtained from chemical synthesis: they can exist in their natural state (such as limonene in orange or geraniol in rose), but can also be created (this is the case for hydroxycitronellal or ethyl-vanillin, for example).
Just like natural molecules, these synthetic ones enhance a fragrance’s richness and olfactory diversity, and feed the perfumer's creativity. While Givenchy Perfumes are composed of both natural materials and synthetic notes, they strictly comply with regulations that restrict the use of certain allergenic materials. However, the main allergens found in perfumes often stem from natural raw materials rather than synthetic substances.
