Rosa damascena
- sourced Dominant Molecule β-Damascenone C₁₃H₁₈O · CAS 23696-85-7 (from the record) · PubChem Compound Summary for CID 5366074, beta-Damascenone
- sourced The Rosa damascena is picked for twenty to thirty days from May in the Rose Valley of Bulgaria, near Kazanlak, between the Balkan and Sredna Gora mountain ranges. · Publication of an application pursuant to Article 50(2)(a) of Regulation (EU) No 1151/2012 (‘Българско розово масло’…
- sourced Picking starts in the early morning and ends around noon, before the heat of the day. It takes an enormous weight of hand-picked petals to make a single kilogram of rose oil. · Publication of an application pursuant to Article 50(2)(a) of Regulation (EU) No 1151/2012 (‘Българско розово масло’…
Jasminum grandiflorum
- sourced Key Molecule Indole C₈H₇N · CAS 120-72-9 (from the record) · PubChem Compound Summary for CID 798, Indole
- sourced For oil the opened flowers are picked by hand early in the day — before 10 a.m., the Tamil Nadu crop guide says — and a great many of them go into a single gram of absolute. · Tamil Nadu Agricultural University (TNAU), TNAU Agritech Portal, “Horticulture :
Aquilaria malaccensis
- sourced Key Molecule Agarospirol C₁₅H₂₆O · CAS 1460-73-7 (from the record) · PubChem Compound Summary for CID 21675005, Agarospirol
- sourced Long-aged pieces are among the costliest materials in perfumery. · Baig et al. (2025). Agarwood in the Modern Era: Integrating Biotechnology and Pharmacology for Sustainable Use
Lavandula angustifolia
- sourced Key Molecule Linalool C₁₀H₁₈O · CAS 78-70-6 (from the record) · PubChem Compound Summary for CID 6549, Linalool
- sourced Fine lavender is rarer and more expensive; lavandin gives almost three times as much essential oil as fine lavender, and a good deal of what is sold as “lavender” is lavandin. · Rosati-Marzetti C, anthropologist: “Les pratiques de culture des lavandes dans les Alpes-de-Haute-Provence”, Fiche…
Mysore Sandalwood
- sourced The fragrant heartwood takes decades to develop, and harvest in India is tightly regulated. The scarcity makes genuine Mysore sandalwood oil one of the costliest materials in perfumery. · Fatima et al. (2022). Comparative transcriptome profiling of high and low oil yielding Santalum album L.
- sourced Mysore oil is rich in α-santalol, the source of its creaminess. · Diaz-Chavez et al. (2013). Biosynthesis of Sandalwood Oil: Santalum album CYP76F Cytochromes P450 Produce Santalols and Bergamotol
- house interpretation The wood was sacred in Hindu and Buddhist tradition for millennia; carved sandalwood keeps its scent for a very long time.
- sourced The heartwood of decades — a prized wood in perfumery, its creamy, milky sweetness hard to match with any synthetic or other species. · Diaz-Chavez et al. (2013). Biosynthesis of Sandalwood Oil: Santalum album CYP76F Cytochromes P450 Produce Santalols and Bergamotol
Calabrian Bergamot
- sourced Raw bergamot contains bergapten, a furanocoumarin that can make skin sensitive to sunlight — which is why perfumery generally uses bergapten-free (FCF) grades. · Navarra et al. (2015). Citrus bergamia essential oil: from basic research to clinical application
Madagascar Vanilla
- unsourced Vanillin is the dominant aromatic compound, but natural vanilla contains hundreds of compounds that give it depth synthetic vanillin cannot match.
Haitian Vetiver
- sourced Vetiver is a tall, perennial grass native to India but cultivated worldwide. · Burger et al. (2017). Vetiver Essential Oil in Cosmetics: What Is New?
- sourced Haiti is one of the leading producers of vetiver oil, and the crop supports a great many small farmers. · Burger et al. (2017). Vetiver Essential Oil in Cosmetics: What Is New?
- sourced With about two hundred compounds on record, vetiver is a chemically complex natural material. · Barcellos-Silva et al. (2025). Vetiver, Vetiveria zizanioides (L.) Nash: Biotechnology, Biorefineries, and the Production of Volatile Phytochemicals
- sourced Khusimol is among its most abundant alcohols, but the smell itself has been traced to a trace ketone, and the full orchestra creates the unmistakable character. · Ouyang et al. (2021). The Smelling Principle of Vetiver Oil, Unveiled by Chemical Synthesis
Florentine Iris
- house interpretation The powdery elegance of orris root — among the costliest natural materials in perfumery.
Omani Frankincense
- sourced Laboratory studies in animals have reported effects of incensole acetate, a compound in the resin; what that means for people burning it is not established. · Moussaieff et al. (2008). Incensole acetate, an incense component, elicits psychoactivity by activating TRPV3 channels in the brain
Perfumery 101
- perfumery convention Every fragrance unfolds in three stages: Top notes hit first (citrus, herbs) and fade first.
- perfumery convention Base notes linger longest (woods, musks) — often for many hours.
- house interpretation Synthetics are lab-created molecules — consistent from batch to batch. Safety depends on the material, not on where it came from.
- perfumery convention Can range from a couple of hours (light citrus) to a full day or more (heavy ambers).
- unsourced A foundation of the classic eau de cologne since the early eighteenth century.
- unsourced The roots of this tropical grass are steam-distilled once the plant is well established.
- house interpretation Hand-picked in India. Its scent was thought so heady that, the story goes, Victorian girls were warned away from it.
- perfumery convention A foundation of the classic amber accord.
