UK vs EU Cosmetic Regulations: Complete Comparison Guide
Since Brexit, UK and EU cosmetic regulations have begun diverging. While both share the same foundation — Regulation (EC) 1223/2009 — the UK now amends its retained version independently through Statutory Instruments, while the EU updates through Commission Regulations. According to UK government guidance, brands selling in both markets must comply with both sets of requirements.

Practical Labeling Solutions
Dual-Market Labeling Options
- Include both UK RP and EU RP addresses on label (one product SKU)
- Use most restrictive ingredient list (EU 80+ allergens covers UK 26)
- Warnings: include all applicable to both markets
- Create separate UK and EU SKUs with market-specific labels
- Use peel-back or booklet labels if space is limited
- Ensure EU labels declare the 80+ allergen list — required on products placed on the market

Practical Compliance Checklist
Dual UK-EU Market Compliance Process
Establish Responsible Persons
Appoint UK RP for GB market and EU RP for EU market. Can be same entity only if established in both jurisdictions. Third-party services available for both.
Verify Ingredient Compliance
Check formulation against BOTH UK Annexes and EU Annexes. Note any differences in concentration limits or restrictions. The more restrictive limit governs if using one formulation.
Prepare CPSR
CPSR can serve both markets if it verifies compliance with both. Document any UK-EU differences. Ensure assessor is qualified under both systems (usually the same requirements).
Submit Notifications
Notify SCPN for GB market and CPNP for EU market. Information required is similar but systems are separate. UK RP submits to SCPN; EU RP submits to CPNP.
Create Compliant Labels
Include both UK RP and EU RP addresses OR create separate market SKUs. Use most restrictive ingredient list (EU allergens cover UK). Add all applicable warnings from both markets.
Monitor Both Markets
Track UK Statutory Instruments and EU Commission Regulations. Update formulations, labels, and notifications when either changes. Confirm EU labels already declare the 80+ allergen list, and plan sell-through of pre-31 July 2026 stock before 31 July 2028.
Yes, but you need to comply with both sets of regulations. This requires: a UK Responsible Person AND an EU Responsible Person, SCPN notification AND CPNP notification, compliance with both UK and EU ingredient restrictions, and labeling that meets both requirements (often achieved by including both RP addresses and using the more restrictive ingredient list).
They share the same foundation (Regulation 1223/2009) but have begun diverging since Brexit. Key differences include: fragrance allergen requirements (the UK retains the original 26; the EU now requires 80+), timing of some ingredient restrictions, and separate notification/RP systems. Many requirements still align, but verification against both is essential.
Northern Ireland follows EU cosmetic regulations under the Windsor Framework. Products sold in NI require an EU Responsible Person and CPNP notification, not UK RP and SCPN. The EU's expanded fragrance allergen requirements (80+ allergens) already apply in Northern Ireland.
Yes, if the CPSR is prepared to verify compliance with BOTH UK and EU Annexes. The assessor should document any differences between jurisdictions and confirm the formulation complies with the more restrictive requirements. Both the UK RP and EU RP should hold copies.
Main differences: (1) RP address must be UK-based for GB, EU-based for EU; (2) Language must be English for GB, official language(s) for EU country of sale; (3) Fragrance allergens: the original 26 for the UK, 80+ for the EU now in force. You can include both RP addresses on one label or create market-specific SKUs.
The transitional provision allowing EU RP addresses on GB product labels ends December 31, 2027. After this date, all products on the GB market must display a UK-based Responsible Person address. Plan relabeling activities well in advance of this deadline.
The UK requires declaration of the original 26 fragrance allergens when above thresholds (0.001% leave-on, 0.01% rinse-off). The EU now requires declaration of 80+ allergens on products placed on its market, following the 31 July 2026 cutoff. For dual-market products, using the EU list (80+) satisfies both requirements, but adds label complexity for UK-only products.
Yes, both UK and EU ban animal testing for cosmetic products and their ingredients. Products animal-tested elsewhere cannot be sold in either market. This alignment has remained consistent since Brexit and is not expected to diverge.
