Sandalwood

History

Sandalwood has been burned, carved and distilled for at least three thousand years. Sanskrit and early Buddhist texts mention chandana (Santalum album) in ritual fumigations and temple carving across India, while Egyptian, Greek and Roman sources record the heartwood traveling along trade routes for funerary balms and incense (Wikipedia, Sandalwood; Britannica, Sandalwood tree, accessed 2026-05-26). The aromatic value sits in the heartwood and roots; the outer sapwood and leaves carry no usable scent.

In modern Western perfumery, Mysore sandalwood became the reference quality from the late nineteenth century onwards. The Karnataka region of southern India produced an oil with an unusually high ratio of santalols, and the resulting profile anchored several of the twentieth century's foundational compositions. Bois des Iles by Chanel (1926, Ernest Beaux) is widely cited as the first modern fine fragrance built around Mysore sandalwood, paired with aldehydes and woody-floral notes (Wikipedia, Bois des Iles; Fragrantica, Bois des Iles, accessed 2026-05-26). Samsara by Guerlain (1989, Jean-Paul Guerlain) and Egoiste by Chanel (1990, Jacques Polge) extended the register, both reported to carry exceptionally high sandalwood dosages.

The contemporary turn arrives with the supply crisis. From the 1990s onwards, decades of overharvesting drove wild Santalum album towards collapse, and the species was placed on the IUCN Vulnerable list and then on CITES Appendix II in 2018, restricting international trade (CITES Appendices; IUCN Red List, accessed 2026-05-26). Niche perfumery responded with two strategies: anchoring on plantation Australian sandalwood (Tam Dao by Diptyque, 2003, Daniel Moliere) and reading sandalwood through synthetic-led modern lenses (Santal 33 by Le Labo, 2011, Frank Voelkl).

Botanical origin

In perfumery, the word sandalwood covers three commercial species of the Santalaceae family, all hemiparasitic trees that draw nutrients from host plants. Santalum album, East Indian or Mysore sandalwood, is native to southern India and the Indonesian archipelago and produces the historic reference oil, with a santalol content typically above 90 percent in well-aged trees (Wikipedia, Santalum album; Eden Botanicals, accessed 2026-05-26). The species was listed under CITES Appendix II in 2018 and rated Vulnerable by the IUCN; harvest in India is held by the State of Karnataka, which has operated a government monopoly on cutting and export since the 1970s.

Santalum spicatum, Australian sandalwood, grows in the semi-arid south-west of Western Australia and supplies most of today's legal volume. The plantation sector around Kununurra and the Goldfields produces an oil with a lower total santalol ratio than Mysore (typically 30 to 45 percent), a drier and more resinous profile, and full traceability (Wikipedia, Santalum spicatum; Australian sandalwood industry data, accessed 2026-05-26). Santalum austrocaledonicum, native to Vanuatu and New Caledonia (France), sits between the two on the profile spectrum, with a softer floral edge and a santalol ratio close to S. album.

Two further species, Santalum paniculatum from Hawaii and the now critically endangered Santalum yasi from Fiji and Tonga, are produced in much smaller volumes and reach perfumery occasionally. None of the African woods sold as "sandalwood" (Osyris species) belong to the genus Santalum, and they yield a different chemistry.

Production and extraction

Sandalwood production is one of the longest cycles on the perfumer's palette. The full sequence, from planting to a saleable oil, runs 15 to 30 years. During the first decade the young tree builds biomass and depends on its host plant; only later does the inner trunk start to convert into aromatic heartwood, the only part used in perfumery. Trees are typically uprooted rather than cut, since the roots carry the highest santalol concentration (Eden Botanicals technical sheet; Wikipedia, Sandalwood oil, accessed 2026-05-26).

The dominant extraction method is steam distillation of the chipped or powdered heartwood. The run is unusually long, typically 24 to 72 hours at low pressure, to release the heavier sesquiterpene alcohols that carry the profile. Industrial documentation reports yields of 2 to 6 percent oil on dry weight, with Mysore Santalum album at the upper end and Australian S. spicatum closer to 2 to 4 percent (Givaudan technical literature; Perfumer & Flavorist sandalwood reviews). Supercritical CO2 extraction has been trialled at smaller scale for fresher, more diffusive profiles but remains marginal in commercial volumes.

The oil is dominated by two sesquiterpene alcohols: alpha-santalol and beta-santalol. The two together account for the bulk of the profile; the ratio differs by species and by age. Premium Mysore material reaches an alpha-santalol plus beta-santalol ratio above 90 percent, the technical benchmark referenced by the Indian Bureau of Standards. Australian S. spicatum contains around 30 to 45 percent total santalols, plus characteristic markers (alpha-bisabolol, farnesol) that contribute its drier facet.

Trade prices reflect the species split. Certified Mysore Santalum album oil from authorised Karnataka stocks trades in a wide bracket: suppliers and trade press cite figures from 2,000 to 4,000 euros per kilogram in 2025-2026 (Eden Botanicals; Perfumer & Flavorist market reports). Australian S. spicatum sits at 800 to 1,500 euros per kilogram. New Caledonian S. austrocaledonicum lands between the two.

Several synthetic captives partially reproduce the sandalwood profile and now anchor most modern compositions outside the rarefied high-end. Sandalore (Givaudan, 1988) opened the modern sandalwood-substitute family, followed by Polysantol (Firmenich, 1980), Ebanol (Givaudan) and Javanol (Givaudan, 2003), the latter prized for an unusually radiant, milky reading at very low dosage (Givaudan technical sheet; Firmenich captives literature; Perfumer & Flavorist molecule reviews). Most contemporary "sandalwood" perfumes published since 2000 combine a small dose of natural oil with one or more of these molecules.

Olfactive profile

Sandalwood reads as creamy, lactonic, warm-woody and softly balsamic, with a quiet sweetness and a milky-skin facet that distinguishes it from cedar, vetiver and oud. Blind, it is recognized by an unusually slow build: little projection on the opening, a gradual heart bloom on warm skin, and a long base anchor that can hold for ten to twelve hours on fabric (Fragrantica, Sandalwood note; Bois de Jasmin, accessed 2026-05-26). The profile differs by species: Mysore is rounder, sweeter, more lactonic; Australian is drier and faintly resinous; New Caledonian sits between the two with a soft floral edge.

On the perfumer's palette, sandalwood works as a base note, with a slow diffusion curve and a structural role rather than a signal role. It binds and rounds heavier wood accords (cedar, vetiver, patchouli), supports floral hearts (rose, jasmine, ylang-ylang) and lends a soft skin facet to ambery and gourmand compositions. Modern niche perfumery has explored its incense-meditative side (Tam Dao, Diptyque), its radical creamy side (Santal Majuscule, Serge Lutens), and its synthetic-led photogenic reading (Santal 33, Le Labo), the polarizing signal-fragrance of the 2010s.

Notable perfumes featuring sandalwood

Six compositions return regularly in the specialised press as benchmarks for the sandalwood note. The selection spans 1926 to 2012 and covers historic Mysore writing, modern niche compositions on plantation oils, and synthetic-led readings.
