The 2026 EU Fragrance Allergen Labeling Update Explained

If you sell into the EU and you've been putting off relabeling your fragranced products, this is the update that makes it unavoidable. Regulation 2023/1545 expanded the list of fragrance allergens that must be disclosed on cosmetic labels, well beyond the shorter list makers have gotten used to working with, and it comes with real sell-through deadlines rather than an open-ended grace period.

Why the allergen list keeps growing

Fragrance allergens are individual aromatic compounds, things like limonene, linalool, citronellol, geraniol, coumarin, and eugenol, that occur naturally in many essential oils and are also used in synthetic fragrance compounds. A meaningful share of the population develops contact sensitization to one or more of these over repeated exposure, so regulators require them to be named on labels once they're present above a set threshold, so allergic consumers can check before they buy rather than finding out the hard way. As more compounds accumulate clinical evidence of sensitization, the list grows to reflect that.

The core logic is the same one behind Canada's own expanding fragrance allergen requirements: disclosure above a leave-on threshold, a higher threshold for rinse-off products, because contact time and concentration both affect sensitization risk.

What's actually changing under the EU update

Under Regulation (EC) No 1223/2009, the EU has required disclosure of fragrance allergens above set thresholds for years. What 2023/1545 does is expand which specific compounds trigger that disclosure, adding a significant number of additional named allergens to the existing list. If your fragrance or essential oil blend contains any of the newly listed compounds above the relevant threshold, they now need to appear in your ingredient list where they didn't before.

For makers using essential oils rather than synthetic fragrance compounds, this matters more than it might first appear, because a single essential oil can contain several allergens at once. Lavender, for example, commonly carries linalool and geraniol. Citrus oils carry limonene. A "natural" fragrance profile doesn't mean a shorter allergen disclosure list; often it means the opposite.

The compliance mechanics you're working with

Under the EU framework, this isn't a standalone filing separate from your normal process. It runs through your existing obligations:

• CPNP notification, the portal notification required before sale.
• A Responsible Person established in the EU, who is accountable for the product's compliance including its label.
• The Product Information File (PIF), which needs to reflect the current allergen content.
• The Cosmetic Product Safety Report (CPSR), signed by a qualified safety assessor, which should account for allergen exposure at the concentrations you're using.

Updating your label for the expanded allergen list means your PIF and CPSR should be checked for consistency at the same time, not treated as a label-only change.

A practical checklist for getting ahead of the deadline

1. Pull your current fragrance and essential oil suppliers' composition data. You need percentage breakdowns of individual allergen compounds within each blend or oil, not just the oil's INCI name.
2. Multiply through. If a fragrance blend is used at 1% in your finished product and contains 5% linalool, that's 0.05% linalool in the finished product, well above most leave-on disclosure thresholds.
3. Check every fragrance-contributing ingredient, not just your named "fragrance" or "parfum" entry. Essential oils used for scent count too.
4. Update your label copy and your PIF together, since a mismatch between the two is its own compliance flag.
5. Confirm your sell-through timeline with your Responsible Person or the current regulator guidance, since exact transition dates and stock rules are the kind of detail that's worth verifying directly rather than assuming from a prior product cycle.

Where this leaves Canadian-only sellers

If you sell exclusively in Canada, the EU update itself doesn't apply to you, but the underlying pattern is worth watching. Canada's own fragrance allergen requirements are on a similar trajectory: List 1 becomes mandatory on the CNF and label on April 12, 2026, and the expanded List 2 becomes mandatory August 1, 2026. If you're already gathering allergen composition data for an EU relabel, you're doing most of the work Canada will also require on its own timeline, which is a reasonable argument for doing this properly once rather than twice.

Cosmetic Comply currently focuses on Canadian notification, mapping ingredients to INCI names and CAS numbers and carrying allergen concentrations through supplier blends, with the EU on its roadmap. If your fragrance data is already organized in a way a filing system can use, both updates get considerably less painful.
