The EU watchlist
Cosmetics sold in the EU run under Regulation (EC) No 1223/2009. Its annexes list what is forbidden outright, what is capped, and what has to be named on the pack. This page collects the entries that matter for face masks, including several that appear in none of the 215 masks we list, because knowing what should not be there is half of reading a label.
A product legally on sale in the EU already complies with all of this. The list is most useful for masks bought outside the EU, for old stock, and for understanding why a formula is put together the way it is.
Banned in EU cosmetics
Annex II. These may not be used at any concentration. If you see one on an ingredient list, the product was not made for the European market.
- Avoid
- Banned in EU cosmetics or credibly linked to serious harm.
Prohibited in EU cosmetic products. Commission Regulation (EU) 2021/1902 added 2-(4-tert-butylbenzyl)propionaldehyde, CAS 80-54-6, to Annex II as entry 1666, applicable from 1 March 2022, following its harmonised classification as a category 1B reproductive toxicant under Delegated Regulation (EU) 2020/1182. It was simultaneously removed from the Annex III declared-allergen list, where it had been entry 83.

- Aluminum GlycinateWell toleratedpH adjuster· in 1 of our masks
Restricted since 2026 as an aluminium-containing ingredient. Regulation (EU) 2026/909, in force since 18 May 2026, added Annex III entry 381, a class entry covering aluminium-containing ingredients apart from a list of named exceptions in Annexes III, IV, V and VI. Aluminum glycinate is not one of those exceptions, so it is caught. The cap is expressed as aluminium rather than as the weight of the ingredient: 10.59% (as Al) in face leave-on products and 0.89% (as Al) in face and body rinse-off products. The SCCS set these levels on the contribution cosmetics make to total systemic aluminium exposure (SCCS/1662/23), not on a hazard specific to this salt. Products that do not comply may not be placed on the EU market from 1 January 2027, nor made available from 1 July 2028, so masks on sale today are unaffected.

- Aluminum HydroxideWell toleratedOther· in 1 of our masks
Restricted since 2026 as an aluminium-containing ingredient. Regulation (EU) 2026/909, in force since 18 May 2026, added Annex III entry 381, a class entry covering aluminium-containing ingredients apart from named exceptions. Aluminium hydroxide does appear in one of those exceptions, Annex VI entry 27a, which is worth reading carefully: entry 27a regulates Titanium Dioxide (nano) as a UV filter and names aluminium hydroxide only as one of the permitted coatings on the particle. The exception therefore covers the aluminium carried on a coated nano titanium dioxide particle, not aluminum hydroxide used as an ingredient in its own right, which is caught by entry 381. The cap is expressed as aluminium rather than as the weight of the ingredient: 10.59% (as Al) in face leave-on products and 0.89% (as Al) in face and body rinse-off products. Products that do not comply may not be placed on the EU market from 1 January 2027, nor made available from 1 July 2028, so masks on sale today are unaffected.

After the SCCS reassessed citral's sensitisation endpoint in 2024 (SCCS/1666/24), Regulation (EU) 2026/909, in force since 18 May 2026, replaced Annex III entry 70 with a table of maximum concentrations by product type. A leave-on mask falls under the leave-on skin row at 0.15%; a wash-off mask falls under the skin rinse-off row at 1.2%. Products that do not comply may not be placed on the EU market from 1 January 2027, nor made available from 1 July 2028, so masks on sale today are unaffected.
