Cosmetics Regulatory Compliance in Europe: EU, UK, Switzerland

On May 1, 2026, Commission Regulation (EU) 2026/78, the eighth in a series of Omnibus acts amending the EU Cosmetics Regulation (EC) No 1223/2009, took effect with no transitional period at all. Eighteen substances, including several forms of silver, multi-walled carbon nanotubes, trimethyl borate and acetone oxime, moved straight into Annex II as prohibited, meaning any cosmetic already on a shelf in the European Union containing one of them became illegal to sell that same day, not on some future sell-through date. Two and a half months later, on July 15, 2026, Great Britain enforced a different ban on a different timeline: its own Statutory Instrument 2026/23 prohibited 3-(4'-methylbenzylidene)-camphor, with a sell-through period running to January 14, 2027, a grace window the EU version never offered.

That gap, same underlying safety science, two different enforcement clocks, is the defining feature of cosmetics compliance in Europe right now. The EU sets the reference regime through Regulation (EC) No 1223/2009, but the United Kingdom has been running its own retained version since Brexit, and Switzerland layers national derogations on top of a framework it otherwise mirrors closely. A compliance team tracking only Brussels will miss real, binding deadlines in London and Bern.

Which regulators actually drive cosmetics enforcement across Europe?

Three separate authorities set the pace, and none of them defers to the others. The European Commission, advised by the Scientific Committee on Consumer Safety (SCCS), amends the Annexes to Regulation (EC) No 1223/2009 through the Omnibus mechanism, while each Member State's competent authority enforces the rules through the mandatory Responsible Person and the Cosmetic Product Notification Portal (CPNP). In Great Britain, the Office for Product Safety and Standards (OPSS) updates the retained, GB-only version of the same Regulation under powers granted by the Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019, while Northern Ireland stays aligned with the EU original under the Windsor Framework. Switzerland's Federal Food Safety and Veterinary Office (FSVO) generally imports the EU Annexes by reference through Article 54 of the Foodstuffs and Utility Articles Ordinance, but Article 6 of its own Cosmetics Ordinance carves out specific national exceptions.

The practical effect is that a formulation legal in Paris on a given date can already be illegal in London, or subject to a stricter limit in Zurich, purely because of which body last touched its Annex.

What changed for prohibited ingredients under Omnibus VIII, and is there a grace period?

Regulation (EU) 2026/78, adopted January 12, 2026 and applicable from May 1, 2026, updated Annexes II, III, IV and V of the EU Cosmetics Regulation to reflect the CMR classifications set by Delegated Regulation (EU) 2024/2564. The Commission added the perboric acid group, several silver forms, multi-walled carbon nanotubes, trimethyl borate, N,N'-methylenediacrylamide and acetone oxime to the Annex II prohibited list, and tightened the concentration limits for o-Phenylphenol in Annex V while adding sodium o-Phenylphenate to the same permitted-preservatives entry. Because none of the affected substances received an SCCS safety opinion supporting continued use, the Commission applied Article 15's default rule for CMR substances: prohibition with no adaptation period. Any product containing a newly banned ingredient had to be off the EU market by May 1, 2026, whether it was newly launched or already sitting in a warehouse.

A separate track is already moving behind Omnibus VIII. Omnibus VI, proposed as COM(2025) 531 final on July 8, 2025 and reaching a provisional political agreement between Parliament and Council negotiators on June 16, 2026, would amend the Cosmetics Regulation again alongside the CLP Regulation and the Fertilising Products Regulation, this time compressing the phase-out clock for future CMR bans to 6 months to stop placing a product on the market and 12 months to stop making it available, while keeping mandatory pre-market notification for nanomaterials.

How far has the UK diverged from the EU cosmetics regime?

Since Brexit, Great Britain runs the retained version of Regulation (EC) No 1223/2009 as its own instrument, updated by OPSS rather than the Commission, and the two tracks no longer move in lockstep. Statutory Instrument 2026/23, laid in January 2026, prohibits 3-(4'-methylbenzylidene)-camphor (4-MBC) from July 15, 2026, with products placed on the market before that date allowed to sell through until January 14, 2027, and separately adds sixteen substances classified as CMR category 1B or 2 under the GB CLP Regulation to Annex II from August 15, 2026, with a sell-through deadline of February 14, 2027. The same instrument lowers the warning-label threshold for formaldehyde-releasing preservatives from 0.05% to 0.001%, also effective July 15, 2026. OPSS notified the WTO on November 27, 2025 of a further draft, a second 2026 instrument, that would add thirteen more CMR substances, including nano silver, ozone and dinitrogen oxide, to Annexes II and III.

Northern Ireland is the exception inside the exception: under the Windsor Framework it continues to apply the EU original directly, so a single UK-wide company can be running three different Annex II lists (Great Britain, Northern Ireland, and whatever the EU passes next) for the same portfolio at the same time.

Why does Switzerland enforce a stricter sun-exposure limit than Brussels?

Switzerland's default position is to import the EU Annexes wholesale, but Article 6 of its Cosmetics Ordinance carves out named exceptions, and furocoumarins are the clearest 2026 example. The EU's Annex II entry 358 caps furocoumarins at 1 mg per kg only in sunscreens and self-tanning products. The revised Swiss Ordinance, in force since January 1, 2026, applies the same 1 ppm limit, but measured as the sum of eight specific furocoumarin markers, to every leave-on cosmetic product that may be directly exposed to sunlight under normal use, a category that reaches creams, oils and lip care products the EU rule does not touch, with perfumes, eau de toilette and cologne carved out. The Federal Department of Home Affairs adopted the amendment on November 20, 2025, and framed it explicitly as a national derogation from the EU Annex, not an implementation of it.

Switzerland's move away from the Cassis de Dijon principle in 2026 compounds the effect: national requirements like this one now reach imported cosmetics as well as domestically manufactured ones, closing a route some companies previously used to sell EU-compliant formulations into the Swiss market unchanged.

What compliance risk sits ahead: PFAS under REACH and the animal-testing question?

Two slower-moving files will shape the next several years. ECHA's Risk Assessment Committee adopted its final opinion on the proposed universal PFAS restriction on March 2, 2026, and the Socio-Economic Analysis Committee closed its public consultation on the draft opinion on May 25, 2026, with a final opinion expected by the end of 2026 before the Commission drafts legislation; industry guidance generally does not expect the resulting restriction to apply before 2029, though cosmetics is one of the sectors where the committees have signaled little appetite for derogations. Separately, the EU's ban on animal testing for finished cosmetics and their ingredients under Article 18 of Regulation (EC) No 1223/2009 does not fully shield ingredient suppliers from REACH: the General Court's November 22, 2023 Symrise ruling confirmed that ECHA can still require vertebrate animal testing on a substance used exclusively in cosmetics if the data is needed to assess risks to workers or the environment, a tension the Commission's June 1, 2026 roadmap toward phasing out animal testing acknowledges but does not resolve on any binding timeline.

Neither of these files has a hard 2026 or 2027 compliance date attached yet, but both will eventually force reformulation decisions with lead times measured in years, not months, which is exactly why they need to sit on a compliance calendar well before a proposal becomes a Regulation.

What should a compliance team do next?

The pattern across the EU, the UK and Switzerland in 2026 is that ingredient bans arrive with less warning, not more. Omnibus VIII gave EU companies zero adaptation time once the SCCS had spoken; the UK's SI 2026/23 at least offers a sell-through window, but on its own separate schedule; and Switzerland can tighten a limit unilaterally even where it otherwise defers to Brussels. Treating Regulation (EC) No 1223/2009 as the single source of truth for a European portfolio will miss the UK's next WTO-notified draft and the next Swiss Ordinance amendment.

Obsidian tracks the EU Omnibus pipeline, the UK's OPSS statutory instruments and WTO notifications, and Switzerland's Cosmetics Ordinance amendments as separate but connected feeds, so a team does not have to check three regulators to know whether a formulation is still sellable everywhere it ships. Setting up per-jurisdiction monitoring flags a new Omnibus regulation, a UK statutory instrument, or a Swiss Ordinance change the moment it publishes, rather than after a customs hold. The AI companion can answer a direct question about a specific Annex entry or a jurisdiction's current sell-through deadline straight from Obsidian's verified regulatory database, and teams running their own compliance tooling can pull the same underlying data through the MCP integration. With the PFAS restriction and the next UK CMR wave both still to land, the safer planning assumption for a European cosmetics portfolio is that 2027 will bring at least as many divergent deadlines as 2026 did.
