UK vs EU Cosmetics Regulation: Key Differences Brands Should Know

Spectra Cosmetic Compliance
For the UK framework itself, see our pillar on the UK retained cosmetics regulation. Here we focus on how it differs from the EU.
One Shared Foundation, Two Diverging Rulebooks
Both regimes descend from Regulation (EC) No 1223/2009, the EU Cosmetics Regulation that governed the UK before Brexit. When the UK left, that regulation was retained as the UK Cosmetics Regulation, becoming the basis of the Great Britain regime. As a result, the two systems share the same architecture: the CPSR, the Product Information File (PIF), the Responsible Person, notification (SCPN / CPNP), labelling rules, and the ingredient annexes all exist in both.
This common foundation is genuinely helpful. A brand that understands EU compliance already understands most of the UK system, and the underlying safety science is identical. The differences lie not in the overall shape of the rules but in specific, important details and, increasingly, in the substance of ingredient restrictions under amendments like Omnibus 2.
Difference 1: Separate notification systems
The most immediately practical difference is notification. The EU uses the CPNP (Cosmetic Products Notification Portal); Great Britain uses the SCPN (Submit Cosmetic Product Notification), operated by the OPSS. Since Brexit, these are separate and independent, with no mutual recognition notifying on one does not cover the other.
A brand selling in both markets must therefore notify twice: on CPNP for the EU and on SCPN for Great Britain. This is a common trap for brands that assume an EU notification still covers the UK. Our guide to SCPN vs CPNP explains the two systems in detail.
Difference 2: Market-specific Responsible Person
Both regimes require a Responsible Person, but each now requires one established in its own market. The EU requires an EU Established Responsible Person; Great Britain requires a UK Established one. Before Brexit, a single EU Based Responsible Person could cover the UK; now, each market needs its own.
For dual market brands, this means appointing (or arranging) a Responsible Person in both the UK and the EU. A UK-based business selling into the EU needs an EU Responsible Person, and an EU-based business selling into Great Britain needs a UK one. Our Responsible Person guide covers the role in each market.
Difference 3: Diverging ingredient rules
This is the difference that is growing fastest. Because Great Britain now controls its own rules, its ingredient annexes can diverge from the EU's. Both regimes restrict and ban ingredients, but they now do so through their own separate instruments the EU through its amendments, Great Britain through its own statutory instruments and these can differ in scope and, importantly, in timing.
A clear example is the treatment of specific substances that both markets have moved to restrict but on different dates. A product compliant in one market may contain an ingredient the other has already restricted, or restricted from a different date. This is why a single formulation can no longer be assumed compliant in both markets without checking each. Our guide to how the UK is diverging explores this trend.
Difference 4: Northern Ireland follows the EU
A crucial structural point is that the Great Britain regime covers England, Scotland and Wales only. Northern Ireland continues to follow the EU cosmetics rules under the Windsor Framework. So within the UK itself, cosmetics are governed by two different regimes depending on the nation.
For brands, this means Northern Ireland aligns with the EU rather than Great Britain for cosmetics purposes. A brand selling across the whole UK must account for both the GB regime and the EU rules that apply in Northern Ireland an added layer of complexity created by the post Brexit settlement.
Difference 5: Separate enforcement
Each regime is enforced by its own authorities. In Great Britain, market surveillance is carried out by the OPSS and local Trading Standards. In the EU, national competent authorities in each member state perform the role. The enforcement powers are broadly similar requesting the PIF, sampling and testing products, requiring corrective action but they are exercised by different bodies under each regime.
In practice this means a dual-market brand may face enforcement attention from either side independently. Compliance in one market does not shield a brand from scrutiny in the other, reinforcing the need to satisfy each regime fully in its own right.
What stays the same
It is worth stressing how much remains common. The core obligations a CPSR, a PIF, a Responsible Person, notification, compliant labelling exist in both regimes. The safety science is identical, so a single safety assessment can often support both markets. Much of the labelling framework and the structure of the ingredient annexes are shared.
This shared core is what makes dual-market compliance manageable rather than a doubling of effort. The discipline lies in respecting the differences on top of the common foundation: separate notification, market-specific Responsible Persons, and increasingly divergent ingredient rules.
What it means for dual-market brands
For a brand selling into both the UK and EU, the practical upshot is to treat them as related but separate compliance streams. Build on the shared foundation one safety assessment, a common approach to the PIF and labelling but manage the market-specific requirements distinctly: two notifications, two Responsible Persons, and separate tracking of each market's ingredient rules.
Above all, keep watch on divergence. The single biggest risk for dual-market brands is assuming that compliance in one market guarantees compliance in the other. As the regimes drift apart, that assumption becomes steadily less safe, and checking products against both markets' current rules becomes essential.
A concrete example of divergence
The clearest way to see why the two regimes must be tracked separately is a real example: the photoinitiator TPO, used in gel nail products. The EU banned TPO in cosmetics from 1 September 2025, with no transitional period. Great Britain banned the same substance, but from a different date 15 August 2026 through its own instrument. Same substance, same direction of travel, different timelines.
For a nail brand selling in both markets, this meant the product had to be TPO free for the EU nearly a year before the GB deadline. A brand that assumed a single compliance position across both markets would either have breached the EU rule by continuing to sell there, or needlessly withdrawn GB stock early. Only by tracking each market’s specific rule and date could the brand act correctly in each.
This is the practical face of divergence. It is rarely that one market bans something the other permits forever; more often, both act on the same substance but on different schedules and through different instruments. Keeping a market-by-market view of ingredient rules and their dates is what allows a dual-market brand to stay compliant in both without over- or under-reacting in either.

Frequently asked questions
Are the UK and EU cosmetics rules the same?
They share a common origin and structure the CPSR, PIF, Responsible Person, notification and annexes exist in both but they are now separate regimes and increasingly diverge, particularly on ingredient restrictions and their timing.
Do I need to notify in both the UK and EU?
Yes, if you sell in both. Great Britain uses SCPN and the EU uses CPNP, and there is no mutual recognition, so notifying one does not cover the other. Both must be done separately.
Do I need a Responsible Person in each market?
Yes. The EU requires an EU Established Responsible Person and Great Britain requires a UK Established one. A single EU based RP no longer covers the UK, and vice versa.
Does Northern Ireland follow the UK or EU rules?
The EU. Under the Windsor Framework, Northern Ireland follows the EU cosmetics rules, while Great Britain (England, Scotland, Wales) follows its own regime. So the UK contains two regimes for cosmetics.
Can I sell the same formulation in both markets?
Often, but not always. As ingredient rules diverge, a substance may be restricted in one market and not the other, or from a different date. Each product should be checked against both markets' current rules rather than assumed compliant in both.
Who enforces the rules in each market?
In Great Britain, the OPSS and local Trading Standards; in the EU, national competent authorities. Powers are similar, but they act independently, so compliance in one market doesn't shield a brand from scrutiny in the other.
What's the same between the two regimes?
The core obligations CPSR, PIF, Responsible Person, notification, labelling and the underlying safety science, which is identical. A single safety assessment can often support both markets, making dual compliance manageable.
Can you give an example of the regimes diverging?
Yes the nail photoinitiator TPO was banned in the EU from 1 September 2025 but in Great Britain only from 15 August 2026. Same substance, different dates and instruments, so a dual-market brand had to track each market’s rule separately to act correctly in both.
