Key data

Official EU ingredient-name evidence

The ingredient name exactly matches the official 2025 EU glossary of common ingredient names.

An exact glossary-name match supports label identity; it does not by itself mean that an ingredient is permitted, safe for every use, or free from annex restrictions. Check the regulatory evidence above.

Additional official and scientific sources

Use identifiers from this page to verify chemical identity, hazard context and market-surveillance evidence. These sources add context; they do not replace the applicable cosmetics law.
