EU Banned Cosmetic Ingredients: The 2026 List

The European Union has the strictest cosmetic regulatory framework in the world. Under Regulation EC 1223/2009, the EU outright prohibits over 1,600 substances from use in cosmetics — listed in Annex II — and restricts hundreds more under specific conditions in Annex III. This is a primer on how that framework works, what’s been added recently, and what the bans actually protect you from.

How the EU system works

Cosmetic regulation in the EU has five core mechanisms:

• Annex II — substances prohibited from use in cosmetic products
• Annex III — substances allowed only under specific conditions (concentration limits, product-type restrictions, mandatory warnings)
• Annex IV — permitted colourants
• Annex V — permitted preservatives, with concentration limits
• Annex VI — permitted UV filters

Annex II is the most consequential for consumers. If a substance is on Annex II, it cannot legally appear in any cosmetic product sold in the EU — full stop, regardless of concentration. The list is updated multiple times per year as new safety evidence emerges.

The EU’s approach differs from the US (where the FDA has banned only about 11 cosmetic ingredients outright) and the UK (which inherited the EU framework post-Brexit and continues to align closely with it).

What got banned in 2025–2026

The most consequential recent additions:

September 2025 Omnibus Act VII

This omnibus regulation added several substances to Annex II and tightened restrictions on others. The headline changes:

• Hexyl salicylate restricted in leave-on products for children under 3
• Specific BHT and BHA formulations restricted under updated concentration caps
• Additional N-nitrosamine precursors prohibited in any product where formation conditions exist

2025 endocrine disruptor additions

Several substances flagged by the SCCS (Scientific Committee on Consumer Safety) for endocrine-disrupting potential were moved from Annex III restrictions to Annex II prohibitions. Notable inclusions:

• Specific cyclic siloxane variants (D4, D5) previously restricted in rinse-off products were extended to leave-on cosmetics
• Additional phthalates beyond the long-standing DBP, DEHP, BBP, DIBP prohibitions

2024–2025 microplastic phase-out timeline

The EU’s broader microplastic restriction under REACH affects cosmetics directly. The phase-out is staged:

• October 2023: rinse-off exfoliating products (immediate)
• October 2027: leave-on cosmetics (including loose glitter, makeup pigments, encapsulated fragrances)
• October 2029: rinse-off products with microplastics that no longer biodegrade

We cover the full timeline in our microplastics article.

The substances most consumers should recognise

Among the 1,600+ Annex II entries, certain categories matter most for typical cosmetic shoppers:

Heavy metals and toxic compounds

• Mercury (and most mercury compounds) — historically used in skin-lightening creams; still found in illegal imports
• Lead (and lead compounds) — historic in older lipsticks; long banned
• Arsenic (and arsenic compounds) — historic in 19th-century cosmetics, banned for decades

Hormonally active compounds

• Hydroquinone — restricted from cosmetic use (still allowed in low concentrations for artificial nail products and in prescription-only formulations for skin lightening)
• Several phthalates — DBP, DEHP, BBP, DIBP
• Specific parabens — isopropylparaben, isobutylparaben, phenylparaben, benzylparaben (the longer-chain parabens); the shorter-chain methylparaben and ethylparaben remain allowed under Annex V. See our paraben deep-dive for the full picture.

Carcinogens

• Coal tar (most fractions)
• Benzene above trace contamination levels
• Asbestos (originally a talc contaminant — now strictly controlled)
• Formaldehyde (banned as direct ingredient; formaldehyde-releasing preservatives still allowed under strict limits with mandatory labelling)

Allergens with high sensitisation risk

• Methyldibromo glutaronitrile (MDBGN) — once a common preservative, banned in leave-on cosmetics in 2007, then in rinse-off in 2008 after rising contact dermatitis rates
• Specific fragrance compounds identified as severe sensitisers — see our 26 fragrance allergens article for the disclosure list

CMR substances (Carcinogenic, Mutagenic, or toxic for Reproduction)

The EU operates a default policy: substances classified as CMR Category 1A, 1B, or 2 under the CLP regulation are automatically prohibited from cosmetic use unless specifically derogated. This is the framework that drove the bans on multiple phthalates, certain solvents, and several historical pigments.

What Annex III actually means

Annex III is where things get more nuanced. A substance on Annex III is allowed, but only under specific conditions. Examples:

• Salicylic acid — up to 2% in leave-on facial products, up to 3% in rinse-off; mandatory warning against use on children under 3 in non-rinse-off products other than shampoo
• Retinol — recent updates cap face products at 0.3% retinol-equivalents and body lotions at 0.05%
• Methylisothiazolinone — banned in leave-on cosmetics since 2017, allowed in rinse-off up to 15 ppm
• Aluminium chlorohydrate (in antiperspirants) — concentration limits and warnings against use on damaged skin
• Specific UV filters — each has a maximum concentration

Reading Annex III correctly matters. An ingredient appearing on Annex III isn’t “banned-but-loophole” — it’s regulated. The cap exists because higher concentrations were assessed and judged unsafe.

We cover this distinction in detail in our Annex II vs Annex III article.

What the EU bans actually achieve

The practical effect of the Annex II/III system is that the average cosmetic product on a European shelf:

• Cannot contain any of the 1,600+ prohibited substances
• Must comply with concentration limits on restricted ingredients
• Must list any of the 26 declared fragrance allergens above the threshold
• Must comply with mandatory warnings for sensitive consumer groups
• Has been notified to the EU CPNP (Cosmetic Products Notification Portal) with a complete ingredient breakdown

This is the regulatory floor. Brands can voluntarily exclude additional ingredients beyond the legal minimum (most “clean beauty” claims operate at this level), but the legal floor itself is meaningful.

How LuxSense uses Annex II/III data

Every ingredient in our database is checked against the current Annex II and Annex III status. An ingredient on Annex II will not appear in any product we score — if it does, the product itself is illegal in the EU. An Annex III ingredient is scored against its allowed concentration window, and our methodology accounts for the position in the INCI list (which roughly corresponds to concentration).

The result: when a product earns a high score on LuxSense, it is not just “well-tolerated by users” — it is also compliant with the most stringent cosmetic safety framework in the world.

FAQ

Where is the official EU banned list?

The current consolidated Annex II is available on EUR-Lex under Regulation EC 1223/2009. It is updated several times per year — by the time most “list of banned ingredients” blog posts are written, they are usually a year out of date.

If something is banned in the EU but allowed in the US, is it dangerous?

Not necessarily. The EU’s precautionary approach prohibits substances on suspected risk; the US generally requires demonstrated harm. Both philosophies are defensible. Practically, EU-compliant products carry a higher floor of regulatory caution.

Is the EU ban list the same as a list of “toxic” ingredients?

No. Some Annex II substances are clearly toxic (mercury, arsenic). Others are banned for sensitisation, photosensitisation, or other concerns that are real but less severe. Banned doesn’t always mean “poisonous.” It means “regulatory assessment concluded it shouldn’t be in cosmetics.”
