The EU Fragrance Allergen Rule, Explained: What Changed on July 31, 2026
Share
As of July 31, 2026, new EU rules mean the fragrance allergens in your body care finally have to be named on the label, and the list roughly tripled. Here is what changed, what the thresholds are, how to read the longer ingredient lists, and why a longer list usually means more disclosure rather than a dirtier product. The bigger picture on why fragrance reactions happen, and why they arrive in perimenopause, is on the Fragrance and Sensitive Skin page.
What changed under the EU's new fragrance allergen rule?
Commission Regulation (EU) 2023/1545, adopted in July 2023, reached its first hard compliance deadline on July 31, 2026. From that date, every cosmetic product placed on the EU market for the first time must individually declare roughly 80 fragrance allergens when they're present above threshold concentrations, up from the 26 that had been required since the early 2000s. Products already on shelves before the deadline have until July 31, 2028 to sell through.
The expansion added 56 substances that the EU's Scientific Committee on Consumer Safety identified as having clearly caused allergic reactions in humans. The disclosure thresholds didn't change: an allergen must be listed when it exceeds 0.001% of a leave-on product (like a body oil or serum) or 0.01% of a rinse-off product (like a body wash). The threshold applies to the finished product, not to the fragrance blend inside it.
Different sources cite 80, 81, or 82 substances, because several entries cover families of related compounds and existing entries were merged or renamed along the way. The precise count matters to compliance teams; for consumers, the practical takeaway is the same: about three times as many fragrance allergens must now be named on the label.
Does this apply to products sold in the US?
Not directly; it's an EU market rule, and US labeling law still allows fragrance components to hide behind the single word "fragrance." But you'll feel it anyway. Most brands of scale sell into Europe and won't run two label systems, so expanded disclosure will show up on US shelves. And the EU list has become the de facto global reference for what counts as a fragrance allergen; clean retail standards and conscientious brands screen against it regardless of where they sell. If a US brand can't tell you how its fragrance performs against the EU list, that silence is informative.
How to read the new, longer ingredient lists
A longer allergen list means more disclosure, not a dirtier product. The Label Decoder sets out the same reading rules in five short sections. The names appearing at the end of ingredient lists (linalool, limonene, citral, geraniol, eugenol, coumarin, and dozens more under the expanded rule) are there because the law requires naming them above tiny thresholds, thousandths of a percent.
| What you see | What it actually means |
|---|---|
| Allergen names listed individually | The brand is disclosing to EU standard; you can check your known triggers |
| The word "fragrance" alone, no allergens | Either allergens sit below thresholds, or the product isn't labeled to EU standard; worth asking which |
| A long allergen list on a fine fragrance | Normal: 15 to 30% fragrance oil concentration pushes many materials over thresholds |
| A short or empty allergen list on a scented body product | Typically a low total fragrance load; concentration, not just composition, kept allergens under thresholds |
That last row is the one that matters most for sensitive skin. Two products can use the same fragrance materials, and the one holding total fragrance under 1% of the formula may trigger few or no disclosure lines while a spray perfume built on the same accord triggers a dozen. Dose is the quiet variable in the entire allergen conversation.
How Pithos screens against the list
We formulate to Credo Clean and Whole Foods Premium Body Care standards: total fragrance held under 1% of the formula, zero synthetic fragrance, every material screened, including against the EU's newly expanded allergen disclosure list. Both Athena and Persephone are built to that standard.
Common questions
What are the deadlines for the new EU fragrance allergen rule?
New products placed on the EU market from July 31, 2026 must comply now. Products already on the market before that date can sell through until July 31, 2028, so you'll see both label styles on shelves for the next two years.
Why do clean products still list things like linalool or limonene?
The EU requires fragrance allergens to be disclosed individually when present above threshold amounts, and that list recently expanded from 26 substances to roughly 80. Seeing those names on a label means the brand is disclosing, not that the product is dirty. The relevant questions are the amount and whether the formula was screened, not whether the words appear.
