The EU Fragrance Allergen Labeling Rules Explained
What changed in 2023, what the 56 new allergens mean for your labels, and when the transition is complete.
You picked up your usual moisturizer and the ingredient list is suddenly twice as long and you are wondering whether the company changed the formula behind your back. They did not. Your headliner’s rider has always had those allergens on it; the EU just started requiring the entourage to write them down. A 2023 regulation added 56 fragrance allergens to the individual labeling requirement, which means your ingredient list is getting more honest, not more dangerous. For anyone whose skin reacts to fragrance, this is the first time the back of the pack tells you what you actually need to know.
The worry budget
| Worth a worry | Not worth a worry |
|---|---|
| A specific fragrance allergen that your patch test identified, now finally visible on EU labels (this is the whole point of the regulation; use it) | A longer ingredient list on a product you have used for years without problems (the formula did not change; the label got more transparent) |
| Buying from non-EU markets where fragrance blends are still hidden behind one word (a US label can say “fragrance” and nothing more) | Memorizing all 82 individually listed allergens (you only need to know the ones you react to; a dermatologist gives you that list) |
| Products on shelves during the 2026-2028 transition that still carry old-format labels (they may not list your allergen even if it is present above the threshold) | The number 56 sounding alarming (these substances were already in products; the regulation names them, it does not add them) |
| Thresholds being labeling triggers, not safety limits (you can react below the declaration threshold; the label is useful but not a guarantee) | EU products being “more dangerous” than before the regulation (more disclosure means more information, not more risk) |
The background: what was already required
Since the original EU cosmetics regulation came into force, products sold in the EU have had to list certain fragrance allergens individually in the ingredient list, in addition to the word “parfum” or “aroma” [2]. Originally, 26 substances were on this list, including widely occurring ones like linalool, limonene, geraniol, citronellol and cinnamal.
The rule is threshold-based:
- Leave-on products (moisturizers, serums, sunscreens): the allergen must be named when present above 0.001% (10 parts per million).
- Rinse-off products (cleansers, shampoos): the threshold is 0.01% (100 parts per million).
Below these thresholds, the allergen does not have to be listed individually. It is still part of the fragrance blend declared as “parfum”.
What changed in 2023
The EU’s Scientific Committee on Consumer Safety reviewed the evidence and identified additional fragrance substances that have “clearly caused allergies in people through skin contact” [3]. Based on that opinion, a 2023 amendment added 56 more substances to the individual labeling requirement, bringing the total to 82 [1].
The same thresholds apply: 0.001% for leave-on and 0.01% for rinse-off.
The transition timeline
The regulation set two dates [1]:
| Date | What it means |
|---|---|
| 31 July 2026 | Products not meeting the new labeling rules can no longer be placed on the EU market |
| 31 July 2028 | Products not meeting the rules can no longer be made available on the EU market (i.e., remaining stock must be off shelves) |
As of late 2026, you may find both old-format and new-format labels on shelves. A product with a shorter ingredient list may simply have been manufactured before the deadline. A product with a longer list may be the same formula with updated labeling.
What this means for you
Longer lists do not mean worse products
The most important point: a longer ingredient list is a sign of more transparent labeling, not a change in the product. The fragrance allergens being named were already present before the label was required to declare them. You are seeing more information, not more ingredients.
You can check for specific allergens
If clinical patch testing has identified a specific fragrance allergen you react to, the expanded labeling makes it easier to check EU-market products. If your allergen is among the new 56, products that previously listed only “parfum” will now name it individually when it is present above the threshold.
Thresholds are not safety limits
The thresholds determine when an allergen must be declared on the label, not the concentration at which it causes a reaction. Some sensitized individuals may react below the declaration threshold. A person sensitized to linalool, for instance, may react to a product containing 8 parts per million in a leave-on formula, which sits below the 10 ppm declaration threshold and would not appear on the label at all. The thresholds are tools for label reading, not guarantees of safety.
This is worth understanding clearly, because it sets what the label can and cannot do for you. The label tells you what is present above a threshold. It does not tell you what is absent. A product with no named fragrance allergens may still contain them at concentrations below the declaration line, and for some sensitized individuals, that is enough to cause a reaction. Your patch test results tell you what to avoid. The label tells you where to look. The two together are useful; neither is complete on its own.
Products from other markets may not have the same labeling
US labels can still list an entire fragrance blend as “fragrance” without naming any components. The Modernization of Cosmetics Regulation Act of 2022 requires FDA to establish fragrance allergen labeling rules, but as of October 2026 no final rule has been published [5]. Products bought from non-EU markets, including online, may not carry the expanded allergen declarations.
This creates a practical gap for anyone who buys from multiple markets. The same fragrance blend may appear as 12 individually named allergens on an EU label and as the single word “fragrance” on a US label. If you rely on the EU labeling to check for your allergens, a product bought from a US retailer will not give you the same information. When in doubt, treat an unlisted “fragrance” as unverified rather than absent.
How to use the new labels
- If you know your allergens: look for their specific names in the ingredient list of EU-market products. The expanded list gives you more to work with.
- If you are just avoiding fragrance generally: the word “parfum” or “aroma” still appears. Individual allergen names after it give you more detail but do not change the basic approach: if parfum is listed, the product contains fragrance.
- If a familiar product suddenly has a longer list: check whether new names appeared at the end. If they are all fragrance allergens, the formula likely did not change.
- If you buy from multiple markets: remember that the same product may carry a different level of labeling detail depending on where it is sold.
Common mistakes during the transition
- Assuming a product was reformulated because the ingredient list is longer. Check whether the new names are all fragrance allergens. If they are, the formula likely did not change; only the label did.
- Panicking about a specific allergen you recognize by name but have never reacted to. Seeing linalool listed does not mean the product is unsafe for you. It means the product is more transparent. If you have used it for years without a reaction, the allergen was always there.
- Trusting that an old-format label has told you everything. During the transition period, a product manufactured before July 2026 may still carry the shorter allergen list. The absence of a newly required allergen name does not mean the allergen is absent. It may mean the label predates the requirement.
- Ignoring the EU labels because you buy from the US. Even if you are based in the US, a product sold in both markets may have an EU-format label available online. Comparing the two tells you what your US label is hiding.
The bigger picture
The EU’s general-population data gives some context. A study that patch tested 3,119 randomly selected adults from five European countries found that 1.9% had a clinically relevant fragrance contact allergy [4]. Among people attending dermatology clinics for suspected contact dermatitis, the rate is much higher. For either group, knowing which specific allergen they react to, and being able to find it on a label, is practically useful.
The expanded labeling is a step toward making that possible for more people. It does not change the chemistry of any product, but it changes what you can learn from the back of the pack.

Exit plan: If you suspect a fragrance allergy, get patch tested to identify your specific allergens by name. That gives you a list to check against. Then switch to EU-market products where those allergens are now individually declared, and check the ingredient list of each new product against your list. That is one new thing at a time. Test it on the seven-to-ten-day arm before using it on your face. During the transition period, double-check whether the product carries the new-format labeling before trusting that your allergen is absent just because it is not listed.
When to see a clinician. If you suspect you are allergic to a fragrance ingredient, a dermatologist can include the fragrance series and specific allergens in a clinical patch test. The result gives you a list of names to check on labels, which is far more useful than a general “avoid fragrance” instruction. Seek urgent medical care for swelling of the face, lips or eyes, difficulty breathing, or a severe or rapidly spreading reaction.
Frequently asked questions
Why are EU ingredient lists getting longer?
A 2023 EU regulation requires 56 additional fragrance allergens to be named individually on cosmetic labels. Products complying with the new rules have longer ingredient lists even if the formula is unchanged. The transition deadline for new products was July 2026; existing stock may be sold until July 2028.
What are the fragrance allergen thresholds?
A named fragrance allergen must appear in the ingredient list when it exceeds 0.001% (10 parts per million) in a leave-on product or 0.01% (100 parts per million) in a rinse-off product. Below those thresholds, the allergen does not have to be named individually.
Does the US have the same fragrance allergen rules?
No. US labels can declare an entire fragrance blend as the single word 'fragrance'. The Modernization of Cosmetics Regulation Act of 2022 requires FDA to establish fragrance allergen labeling rules, but as of October 2026 no final rule has been published.
Does a longer ingredient list mean a product is less safe?
No. The longer list reflects more transparent labeling, not a change in the product. A fragrance allergen named at a very low concentration was already in the product before the label was required to list it.
