SILICON CARBIDE
Official label name (INCI name, EU glossary of cosmetic ingredient names), No 26072
- Prohibited in cosmetics (Annex II)
SILICON CARBIDE: Prohibited in cosmetics (Annex II, entry 1658), under Regulation (EC) No 1223/2009.
In plain words
What it is used for
Functions declared by manufacturers:
Abrasive: removes materials from various body surfaces or aids mechanical tooth cleaning or improves gloss.
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
A specific form or grade of this substance (the one described in the title of the CLP entry) is classified as carcinogenic, category 1B (presumed effect, established mainly from animal studies). Its other forms fall under another entry.
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).

Classified hazard (CLP Regulation)
A classification describes an intrinsic hazard, not a risk: the risk depends on the dose, the form and the exposure.
