About
A cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Quinoline derivatives extracted from coal tar are used industrially as solvents and chemical intermediates. Quinoline itself is classified by IARC as Group 2A (probable human carcinogen). The conditional benzene flag adds additional EU Annex II concern. Under EU Regulation 1223/2009, coal tar-derived substances with aromatic contamination are prohibited in cosmetic products, and no SCCS safety opinion supports their use in skincare.
Known concerns
- Quinoline derivatives — IARC Group 2A probable carcinogen
- Benzene >0.1% w/w — EU Annex II prohibited
- Coal tar origin raises additional PAH and heavy metal contamination concerns
- No established cosmetic function or safety profile
