“…In general, a clustering can be done into orange and lemon type oils, differing in their content of β-pinene (10), γ-terpinene (11) [40] and citral (13). Lemon and lime oils show with up to 14 % of β-pinene (10), [41] up to 22 % of terpinolene (26) and 3-13 % of citral (13) [42,43] a significantly higher content compared to sweet orange oil and grapefruit oil, where (R)-limonene (8) [44] remains the main constituent (Figure 3). [45] Interestingly, a citrus oil's character and value to perfumery is decided by the quality of the essential oil, represented by its profile of trace component.…”

In this review, the impact of the transition from today’s petrochemical economy towards a 100/100 renewable and biodegradable future is discussed: “citrus”, “green”, “fruity”, “floral”, “floriental”, “oriental”, “woody”, “chypre” and “fougère”. After benchmark data on ingredients usage, definitions on biodegradation and sustainability are given. Celebrating the 150th anniversary of svanillin, its historic synthesis from renewable starting materials serves as introduction. Citrus scents upcycled from the beverages industry are already an ideal case for 100/100 with new opportunities for artificial essential oils. In the fruity domain, transparent and lactonic ingredients are available in a sustainable manner. In the domain of green odorants, there is a lack of green chemistry for important key materials. In the floral family, renewability is more critical than biodegradability, but cost is an issue. Thanks to Ambrox and maltol, florientals and orientals will persist, while woody notes severely lack an Iso E Super replacer. In the chypre genre, patchouli became the new moss, but more musks are increasingly in demand. With their high percentage of linalool and dihydromyrcenol, the construction of fougères could well become a precedent for other families, despite challenges in vetiver and salicylates. Still, the challenges exemplified create immense opportunities for new perfumery materials
