About

4-METHYLQUINOLINE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

Quinoline and its derivatives have been associated with carcinogenic potential in toxicological studies. This ingredient is not listed in EU Regulation 1223/2009 Annexes, indicating it is not authorized for cosmetic use in the EU. The absence from approved ingredient lists means it cannot be used in cosmetic products sold within the European Union.
