Updated in November 2026: the proposal we described is now Regulation (EU) 2023/1545 and its first deadline already applies.
The EU Cosmetics Regulation required 24 fragrance substances to be labelled above 0.001% in leave-on and 0.01% in rinse-off products. Fragrances are among the most common allergens in cosmetics: the Scientific Committee on Consumer Safety (SCCS) estimates that 1% to 3% of Europeans are allergic to at least one.
What Regulation (EU) 2023/1545 changes
Following the SCCS opinion of 2012 and years of assessment, Regulation (EU) 2023/1545 amended Annex III of Regulation (EC) 1223/2009 and extends the list to more than 80 allergens, adding individual substances as well as complex natural substances such as some essential oils.
The labelling thresholds stay the same (0.001% and 0.01%).
Deadlines
- From 31 July 2026, new products placed on the market must comply.
- Until 31 July 2028, products already on the market before then may still be sold; after that, all products must comply.
The impact on the chain
To declare an allergen on a finished product label, the manufacturer needs its concentration in each fragrance and raw material. That means:
- Asking suppliers for updated declarations covering all 81 allergens.
- Recalculating concentrations in every formula.
- Updating labels and allergen certificates for customers.
Detergent manufacturers are affected too, because the Detergents Regulation refers to the same fragrance allergen list.
How Kemchain helps
Kemchain Suppliers automates supplier requests and uses AI to extract allergens from their declarations and data sheets, with their source. You see at once which raw materials contain each allergen and at what concentration. With Kemchain Formulations (coming soon) you will issue allergen certificates from the formula.
