Great Britain cosmetic ingredient regulations
GB rules must be versioned separately from EU rules as they diverge.

- GB retained Regulation 1223/2009 schedules, effective 15 August 2026
What this list is
Great Britain carried EU Regulation 1223/2009 onto its own statute book after Brexit and has amended it separately ever since. The two lists started identical and no longer are, which is why a GB check cannot be answered from an EU one.
- 2,329 GB records: 1,758 prohibited, 326 restricted, 245 on a positive list.
- The regulator is the Office for Product Safety and Standards, not the European Commission.
- GB and EU annexes are amended by different bodies on different dates, so they drift apart substance by substance.
- A substance absent from the GB list is not thereby permitted — absence is absence of a record, not a decision.
The Cosmetic Products Enforcement Regulations 2013 kept Regulation 1223/2009 in force in Great Britain after EU exit, so the structure a formulator already knows — Annex II for prohibited substances, Annex III for restricted ones, Annexes IV to VI for colourants, preservatives and UV filters — is the same here. What changed is who amends it. The Office for Product Safety and Standards now does that for Great Britain, and the European Commission does it for the EU, on their own timetables.
That divergence is the practical point of this page. When the Commission adds a substance to Annex II, Great Britain does not follow automatically. The reverse holds too. Two lists that began as one copy now differ entry by entry, and the gap widens with each amendment cycle, so a compliance answer for one market is not evidence for the other even when the substance and the wording look identical.
Northern Ireland is not covered here. Under the Windsor Framework it continues to apply the EU regulation, so a product placed on the market across the whole United Kingdom is answering to two rulebooks at once. Check the EU records for that half.
The 2,329 records below carry the status the GB source gives them and nothing more. Where a record is marked restricted, the concentration limit, product-type condition and warning text come from the source as written; where a substance has no record at all, that means no GB entry was resolved here, not that its use has been considered and allowed.

How Great Britain differs from other markets
Comparing this market's imported rules against every other market's for the same substance. A market with no imported rule for a substance is left out of that comparison rather than treated as permitting it.
A formula cleared elsewhere can fail here.
Permitted here under conditions and prohibited, or more tightly held, elsewhere — so a formula built for this market may not travel.

Source and authority
Identify the official material and the regulator responsible for it: Office for Product Safety and Standards.
Language and scope
See whether usable English or bilingual material exists and what the mapped source actually covers. Current source language: English.
Evidence status
Browse ingredient-level records imported from official sources. Each row states whether it passed deterministic source checks or human editorial review.
How to verify an ingredient for this market
- Search the ingredient by INCI name, CAS number or EC number and record the exact identity.
- Open each official source above and check the current version, product scope, concentration limits and required warnings.
- Confirm effective dates and whether an English text is official, reviewed or only contextual.
- Treat a missing local match as unknown, never as permission or a safety conclusion.
