TETRAMETHRIN
Official label name (INCI name, EU glossary of cosmetic ingredient names), No 28583
- Prohibited in cosmetics (Annex II)
TETRAMETHRIN: Prohibited in cosmetics (Annex II, entry 1618), under Regulation (EC) No 1223/2009. Annexes of the Regulation consulted on 21 October 2026.
In plain words
What it is used for
Functions declared by manufacturers:
Antimicrobial: helps control the growth of micro-organisms on the skin.
What the rules say
It is prohibited to use it in a cosmetic product sold in the European Union, whatever the dose. If it appears on the ingredient list of a recent product, this needs checking: the record may be old or wrong, or the product intended for another market.
Hazard and risk
The CLP Regulation classifies this substance as carcinogenic, category 2 (suspected effect, without enough evidence for a higher category).
This classification describes what the substance can cause (a hazard), not what happens when using a product (a risk): the risk depends on the dose, the form and the route of exposure (skin, inhalation, ingestion).
Already prohibited in cosmetics (Annex II).
