Bergamot peel pressed in Calabria, rose petals picked by hand in Bulgaria, a lichen on oak bark. Chypre is the most clearly structured family in perfumery, and this piece rebuilds that structure with essential oils, with a Lê Mai blend checked against IFRA limits.
Three materials and an island
Chypre is the French name for Cyprus. In the classification of the Société Française des Parfumeurs, the Chypre family carries the code D and groups compositions built mainly on three materials: oakmoss, labdanum from the cistus shrub, and patchouli. Bergamot usually sits above them. Rose and jasmine usually sit in the middle.
The family is named after one bottle. François Coty released Chypre in 1917, with bergamot at the top, rose and jasmine in the heart, oakmoss, labdanum and patchouli in the base. The word Chypre had circulated in perfumery for centuries, attached to preparations such as Poudre de Chypre, a scented powder based on oakmoss, but only after 1917 did it become the name of a structure. The original formula is kept by the Osmothèque in Versailles.
The identifying mark of Chypre is a contrast: the bright sourness of citrus peel above, the damp, bitter, faintly smoky oakmoss below. The two ends do not merge like a two material accord. They are held apart, and the floral tier in the middle forms the bridge.
From that frame the Chypre family split into seven SFP subfamilies: with fruit, as in Mitsouko of 1919, with leather, with the green note of galbanum, with aromatic herbs, with aldehydes. All seven still stand on the same axis of citrus, flower, moss.
Bergamot at the top
Bergamot is a citrus native to Calabria in southern Italy. The fruit is small, thick skinned and inedible. The oil is cold pressed from the peel with no heat. Its main constituents are limonene, linalyl acetate and linalool; the ester and alcohol pair gives bergamot a lightly sour, slightly floral scent, unlike sweet orange, which is almost entirely limonene.
Bergamot peel also contains furocoumarins, mainly bergapten. When the oil penetrates skin that is then exposed to UV, bergapten causes a phototoxic reaction. The library gives a maximum of 0.4 percent for cold pressed bergamot in leave-on products exposed to sun, and the EU caps bergapten at 15 ppm in leave-on cosmetics.
Bergamot FCF is the grade with bergapten and other furocoumarins removed by fractional distillation or adsorptive filtration. The library notes that FCF is not phototoxic and can be used up to 16.6 percent on skin under the SCCNFP bergapten threshold. In return, FCF smells lighter than cold pressed bergamot; part of the signature character leaves with the furocoumarins.
On a blotter this tier leaves first. The library's volatility chart has a figure only for bergapten reduced bergamot: about 8 hours. In a Chypre the citrus tier does not need to stay long. It only needs to be bright enough in the opening to set up the contrast with the base.
Rose in the heart
The heart of a classic Chypre is rose and jasmine. The floral tier does not stand alone; it links the bright top to the dark base. If it is too thin, citrus and moss stand side by side with nothing between them. If it is too thick, the Chypre turns into a floral with a mossy ground.
Damask rose gives this tier a sweet, deep rose scent, with citronellol and geraniol as its two main alcohols. But rose also carries methyleugenol, at 0.5 to 3.3 percent. The library gives the IFRA limit for methyleugenol as 0.02 percent in fine fragrance and 0.0004 percent in body lotion. In a perfume, rose stops at about 0.6 percent of the finished product.
Geranium is the way to hold the floral tier when rose must be small. Geranium oil contains citronellol at 19 to 48 percent and geraniol at 7 to 30 percent, the same two main molecules as rose. The library's substitution chart lists geranium as a common alternative to rose for that reason. Geranium has a maximum dermal level of 17.5 percent, based on geraniol.
In this blend rose takes only one drop, geranium four. Rose gives depth; geranium gives volume. The rose and patchouli accord was built in the blending course, and the piece on rose and patchouli goes further into the history of the pair.
The earth base: oakmoss and patchouli
Oakmoss is the lichen Evernia prunastri growing on oak bark, harvested mainly in the Balkans and Morocco. Its scent is damp, earthy, slightly salty, with an inky facet. It is the material that made the Chypre family's name, and the most tightly regulated one in it.
Oakmoss contains atranol and chloroatranol, two strong skin sensitisers. Regulation (EU) 2017/1410 placed both on the list of substances prohibited in cosmetics; from 23 August 2019 new products containing them could not be placed on the EU market. The IFRA Standard requires each below 100 ppm in oakmoss extract and caps the extract at 0.1 percent in fine fragrance. Oakmoss in use today is a low atranol grade, lighter and less inky than older grades.
Patchouli carries most of the base in a modern Chypre. The library describes it as woody, earthy, warm, deep, balsamic, with a faint camphor trace when new and softer with age. Patchouli has no IFRA concentration limit of its own. Under Regulation (EU) 2023/1545, patchouli oil and bergamot oil are both on the expanded list of fragrance allergens that must be labelled; new products placed on the EU market after 31 July 2026 must comply.
The library's Chypre page notes that after 2000 many formulas cut oakmoss sharply and leaned more on patchouli, woods and synthetics. The trade often calls this group modern Chypre. The piece on oakmoss covers this lichen and the rules around it in more detail.
The Lê Mai chypre blend
The blend below builds the Chypre structure only from oils that have a library page, without oakmoss. The finished form is an alcohol perfume, 10 ml, 15 percent oils in perfumer's alcohol, that is 30 drops of oil. This is eau de parfum strength by trade convention, and the relevant limits are those for fine fragrance, IFRA category 4.
The top is bergamot FCF, nine drops, close to a third of the blend. The heart is one drop of damask rose and four of geranium. Clary sage, four drops, sits between heart and base: linalyl acetate links to the bergamot above, sclareol moves down into the ground. The base is nine drops of patchouli and three of cedarwood.
On a blotter this structure opens with lightly sour citrus peel, moves to rose and geranium, then leaves a ground of earth and dry wood for days. The Chypre contrast lies in the distance between the first hour and the second day. The blend should rest for a few weeks in a dark bottle before a final judgement.
| Essential oil | Drops | Share of blend |
|---|---|---|
| Bergamot FCF | 9 | 30% |
| Damask rose | 1 | 3.3% |
| Geranium | 4 | 13.3% |
| Clary sage | 4 | 13.3% |
| Patchouli | 9 | 30% |
| Cedarwood (Himalayan) | 3 | 10% |
IFRA category 4 (fine fragrance). The level in the finished product equals the share in the blend times 15 percent: bergamot FCF 4.5%, rose about 0.5%, geranium and clary sage about 2% each, patchouli 4.5%, cedarwood 1.5%. Shares are rounded, so the displayed total is 99.9%.
The limiting oil is damask rose. Its maximum dermal level is 0.6%; at about 0.5%, methyleugenol (up to 3.3% of the oil) comes to about 0.017% of the product, below the IFRA limit of 0.02% for fine fragrance. Do not use this blend as a lotion or body oil, where the methyleugenol limit is 0.0004%.
Bergamot FCF is below its 16.6% level and is not phototoxic. Geranium is below 17.5%; total geraniol from geranium, rose and clary sage stays under 0.8%, far from the 5.3% limit. Patchouli has no IFRA limit of its own. Cedarwood has no maximum listed in the library; it is kept at 1.5% because its sensitisation risk is recorded as moderate. No oakmoss is used.
Chypre without oakmoss
According to the library's Chypre page, the base of a Chypre needs three roles: something damp and bitter, something warm and resinous, something earthy and woody. Oakmoss takes the first role, labdanum the second, patchouli the third. Without oakmoss, the first role has to be shared among the others.
In this blend patchouli carries the earth. Clary sage carries sclareol, a molecule described as warm, balsamic, lightly musky, and the Chypre page notes that clary sage adds a dry ambery touch to the base. Cedarwood adds dry wood. None of the three has the inky, salty note of oakmoss; the blend rebuilds the impression of earth and dryness, not oakmoss itself.
The library's substitution chart offers another direction: patchouli and vetiver with labdanum to recall the mossy feel of Chypre. That is a variant worth testing, replacing cedarwood with vetiver, or adding a share of labdanum. Each change needs a control blotter and a new limit check.
Low atranol oakmoss can still be used in perfume at very low levels, below 0.1 percent of the finished product under IFRA. In 10 ml that is less than one drop; in practice it has to be diluted before measuring. The Lê Mai blend chooses not to use it, so that the structure stands on bottles already in the cabinet.
Chypre is a distance, between citrus peel and the ground.
Oakmoss has left; the structure remains.
What stays on the blotter after two days is the real name of this family.
