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.
