Is Oakmoss Still in Perfume? 54 Fragrances Publish It, and the EU Changed What the Word Can Mean

Start with the part that matters, because the interesting version of this story is not the one that sounds like a scandal.

Nobody here is doing anything wrong. Oakmoss is not banned. Fifty-four fragrances in our corpus publish a moss note, and as far as we can tell every one of them is entitled to.

What changed is the material the word points at.

What the regulation actually did

Atranol and chloroatranol occur naturally in oakmoss (Evernia prunastri) and treemoss (Pseudevernia furfuracea). The EU’s Scientific Committee on Consumer Safety identified them as among the fragrance allergens responsible for the largest number of contact allergy cases, and Regulation (EU) 2017/1410 added them to Annex II of the Cosmetics Regulation, the list of substances prohibited in cosmetic products.

The prohibition landed in stages. From 23 August 2019 no new non-compliant product could be placed on the EU market. By 23 August 2021 any remaining stock had to be withdrawn.

Crucially, the ban names the constituents, not the botanical. Oakmoss extract treated to bring atranol and chloroatranol below 100ppm stays legal, and the IFRA Code of Practice permits it up to 0.1% in a finished product.

So the word survived. The material under it was reformulated across the industry, and the reason “the regulation that killed chypre” became a standing complaint among perfumers is that the treated version is widely reported to smell different from what it replaced.

What we found

We hold 1,583 fragrance profiles whose note lists come from a brand-official page or an authorized retailer. We asked a narrow question: how many still publish a moss note?

54 do. 47 of those 54, or 87%, are sourced from the house’s own website.

This is not the story you might expect

The obvious framing would be that budget houses are sloppy with their copy. The data says otherwise, and says it clearly.

Mancera	11
Nishane	6
Elizabeth Arden	3
Al Haramain	3
Armaf	3

Lattafa	3

Paco Rabanne	2

A French niche house and a Turkish niche house lead the set. The rest runs from Creed, Tom Ford, Hermès, Roja Parfums and Santa Maria Novella through Davidoff, Versace and Calvin Klein to Lattafa, Armaf, Afnan and Al Haramain. Twenty-seven houses, every tier of the market, luxury and accessible alike.

That 45 of the 54 put the moss in the base is unsurprising and worth stating anyway: the base is where oakmoss has always sat in chypre and fougère construction. These are not decorative mentions. They are structural claims about the bones of the fragrance.

The actual finding

The material changed. The word did not.

A reader comparing a pyramid published in 2018 against the same house’s page today sees identical text. Nothing in the note list records that a regulation intervened between those two dates, or that any oakmoss legally used in an EU-market fragrance now must be a treated low-atranol material rather than the absolute that word used to mean.

This is not deception. A house using treated oakmoss and printing “oakmoss” is describing its material accurately. The problem is resolution: one word now covers two materials, and the published note cannot distinguish them.

⚠️ One limit we have to state, because it cuts against the tidy version. Our sources include official US stores as well as EU ones, and the EU prohibition binds products placed on the EU market. A fragrance made for another market may legally use untreated oakmoss. That makes the picture worse rather than better for anyone reading a pyramid: the same word now spans materials that differ by regulatory regime, and the note list does not tell you which regime produced the bottle in your hand.

What this does to our own work

We publish a study comparing 34 pairs of brand-published note lists. Its entire premise is that a published list is citable evidence of what a house claims.

Four of those 34 pairs are affected by this finding, including Lattafa Ana Abiyedh Rouge, which is the headline exhibit in that study’s Baccarat Rouge 540 comparison.

So this result constrains our own method, and we would rather publish that than have it pointed out to us. A published note list remains the best available evidence of what a house says. It is not evidence of what is in the bottle, and this is a measurable case where the two came apart without the text moving. Any comparison of note lists across time carries an unstated assumption that the words meant the same thing at both ends. Here, demonstrably, they did not.

The document people actually think they are reading

Much of the confusion dissolves once you notice there are two published disclosures per fragrance, and only one of them is regulated.

The INCI ingredient list is legally mandated in the EU under Regulation 1223/2009. It names declarable substances, currently 24 fragrance allergens, rising to 81 under Regulation (EU) 2023/1545 for products placed on the EU market from 31 July 2026. It is an audited, enforceable document.

The note pyramid is marketing copy. It is written to evoke a scent, no regulation governs its wording, and nothing requires it to be revised when a formula changes.

Both appear on brand websites. They look like they are describing the same thing. Only one of them is answerable to anybody.

Method

Our corpus is 1,583 fragrance profiles whose note lists are captured from a brand-official page or an authorized retailer, each stored with its source name and URL. We searched published note text for oakmoss, treemoss, tree moss and mousse de chêne on word boundaries.

We deliberately excluded a larger, softer set. Accord names such as lily of the valley, muguet, cyclamen and linden blossom were historically built using Lilial (BMHCA, prohibited from 1 March 2022) and Lyral (HICC, prohibited alongside atranol). Including them would have produced a bigger number and a weaker claim, because a house can build a muguet accord from many materials and after the ban must. A moss note is different: the note name is itself the botanical source of a prohibited constituent. That is why the headline figure is 54 and not 110.

⛔ What this study does not claim. It does not claim any product is non-compliant, contains a prohibited substance, or has been reformulated. We have not tested any liquid and we make no assertion about what is in one. Every finding here concerns published text and nothing else.
