About
Chlorothalonil is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.
Chlorothalonil is a dichloro aromatic fungicide used extensively in agriculture. While not categorically banned like some substances on this list, EU restrictions apply under Regulation 1223/2009 due to sensitization concerns. SCCS reviews have identified potential carcinogenic concerns at high doses, and H317 (skin sensitizer) and H318 (serious eye damage) classifications apply. Residues in agricultural commodities raise incidental exposure concerns for cosmetic raw materials derived from plant sources.
Known concerns
- Known skin sensitizer (H317)
- Serious eye damage potential (H318)
- Suspected carcinogen with mechanism involving reactive metabolites
- Environmental degradation to toxic compounds
- DDCS (dichloroisonicotinic acid) skin irritation concerns
