A lily-scented fragrance (Lilial) banned in the EU in 2022 as toxic for reproduction — scent only, no skin function.
What it does
Butylphenyl methylpropional, often called Lilial, is a synthetic fragrance with a lily-of-the-valley scent that was widely used to add a clean floral note. The EU banned it from cosmetics in 2022 after classifying it as toxic for reproduction, so brands have been reformulating to remove it; you may still see it on older stock or non-EU products. Its role was scent only, with no skin function.

The evidence, graded
expert consensusButylphenyl methylpropional, the lily-of-the-valley fragrance sold as Lilial, has been prohibited in EU cosmetics since 1 March 2022 under Commission Regulation (EU) 2021/1902. It was classified as toxic for reproduction, category 1B. That ban is about reproductive toxicity, not allergy, though it is also one of the EU's 26 labeled fragrance allergens. A product made for another market, or older stock, can still list it.EU 2021 · Official Journal of the European Union ↗ Graded per the methodology: strong · moderate · emerging · expert consensus.
