What this list is

The EU list is not one list. Regulation 1223/2009 splits substances across five annexes that answer different questions, and reading the wrong one is the most common way to get an EU answer wrong.

  • Annex II prohibits 1,739 substances outright.
  • Annex III permits 373 substances only within stated limits, product types and warnings.
  • Annexes IV, V and VI are positive lists: 154 colourants, 54 preservatives, 33 UV filters.
  • For those three categories, absence from the annex means not permitted — the opposite of Annex II's logic.
  • CosIng is a discovery database, not the law; the annexes as published are.

Most markets on this site publish one list. The EU publishes five, and they do not work the same way. Annex II names substances that may not be used at all. Annex III names substances that may be used, but only within a concentration limit, for stated product types, and often with a warning that must appear on the label. Annexes IV, V and VI are positive lists for colourants, preservatives and UV filters.

That last distinction reverses the logic and catches people out. For a substance in general, absence from Annex II is not permission — nothing has been decided about it. For a preservative, absence from Annex V is a decision: it may not be used as a preservative in a cosmetic product. The same silence means opposite things depending on which annex you are reading.

CosIng is worth naming separately, because it is what most searches land on. It is the Commission's database for finding ingredients and their annex references, and it is genuinely useful for that. It is not the legal text. When CosIng and the published annex disagree — usually because an amendment has come into force and the database has not caught up — the annex governs.

An Annex III entry is also more than a number. The limit, the product-type condition and the warning text travel together, and quoting the concentration without the condition it applies to produces an answer that is right about the figure and wrong about the product.

If no match is found
No annex match only means that these five annexes did not return a match; CosIng identity data and other EU obligations still need review.

Complete verification checklist

  1. Confirm the exact INCI/CAS/EC identity.
  2. Review every matching Annex II–VI row and its conditions.
  3. Check SCCS opinions, CMR/nanomaterial rules and later amendments.
  4. Verify product classification, claims, labelling and responsible-person duties.

How to verify an ingredient for this market

  1. Search the ingredient by INCI name, CAS number or EC number and record the exact identity.
  2. Open each official source above and check the current version, product scope, concentration limits and required warnings.
  3. Confirm effective dates and whether an English text is official, reviewed or only contextual.
  4. Treat a missing local match as unknown, never as permission or a safety conclusion.
