The EU's cosmetics allergen list grows from 26 to 82 substances on 31 July — and the Commission corrected three entries eight months after most brands had already locked their mapping

What actually changes, and when

Directive 2003/15/EC introduced the individual-labelling duty for 26 fragrance allergens (24 individual substances plus two natural extracts — oakmoss extract and treemoss extract) above 0.001% in leave-on products and 0.01% in rinse-off products. That list had not moved in two decades. Commission Regulation (EU) 2023/1545 of 26 July 2023 (OJ L 188, 27.7.2023; entered into force 16 August 2023) added 56 new fragrance allergens to Annex III of Regulation (EC) No 1223/2009, taking the individually-declarable list to 82 substances. The concentration thresholds themselves were not touched — still 0.001% / 0.01%. The regulation split the transition into two dates: cosmetic products may be placed on the EU market for the first time without declaring the new allergens only until 31 July 2026; products already placed on the market by that date may continue to be made available for sale until 31 July 2028. Then, in November 2025 — about eight months before the first deadline — the Commission published a corrigendum in the Official Journal (OJ 2025/90876) making three changes to the Annex III text itself: renaming "Rose ketone 4 (Damascone)" to "Rose ketone 4 (Damascenone)"; splitting the "Pelargonium Graveolens Flower Oil" entry to separately cover Oil, Flower Oil and Leaf Oil; and adding a wholly new entry, Pogostemon Cablin Leaf Oil (patchouli leaf oil). The corrigendum left both deadlines untouched.

From 26 to 82

Before 31 July 2026, the compliance question was already familiar to the industry: the 2003 directive required individual declaration of 26 fragrance allergens above the same thresholds that still apply today. What changes with Regulation 2023/1545 is not the mechanism — it's the scale. 56 additional substances join the list at once, more than doubling the original count, on detection thresholds that have not moved in two decades. For a brand selling fragrance, scented body care or fragranced leather-care products into the EU, that means a formula that has been stable for years can fall into a declaration obligation simply because the reference annex expanded around it — without a single ingredient in the formula changing.

The real subject: Annex III is a living dataset, not a text you read once

What used to be a single compliance question — "does our label carry every Annex III allergen above threshold?" — became a moving target during the very runway the Commission gave industry to answer it. The original 2023 text is no longer the current text: brands and labs that built their formula-to-Annex-III mapping directly from the July 2023 regulation, without tracking corrigenda since, are working from an allergen list that no longer matches what a market surveillance authority will check against from 1 August 2026. The gap concerns only three entries, but it is representative of a broader pattern for this kind of "living annex" regulation: Annex III is not a document a brand can capture once and label against for two years — it is a reference dataset that keeps moving until the day compliance is actually checked. For any brand mapping SKU-level fragrance formulations against Annex III, the compliance question isn't just "did we cover the 56 new substances" — it's "is our reference copy of Annex III even the current one."

Why it matters for brands

Any brand selling fragrance, eau de toilette, scented body care, home fragrance, or fragranced leather- or textile-care products into the EU needs SKU-level formulation data that can be checked, ingredient by ingredient, against the current 82-entry Annex III list before 31 July 2026 for any product entering the market for the first time — a scented leather-care spray or a new fragrance launch is squarely in scope. Products already sitting in EU distribution get until 31 July 2028, but only if they were genuinely placed on the market before the first cliff-edge — a brand that assumes it is covered because a product "already shipped" needs the paperwork to prove the placement date, not just the shelf date. And because the reference list itself moved eight months before the deadline, the operational risk is not only formulation gaps; it includes compliance debt baked into a mapping exercise finished against a text the Commission has since corrected.
