Disperse Blue 3 (CI 61505) is an anthraquinone dye regulated under EU CosIng as a hair dye precursor with restriction entry II/1300, limiting its use in oxidative (permanent) hair dye systems. As an azo dye derivative, it falls under the EU azo dye restriction (REACH Annex XVII) due to potential release of carcinogenic aromatic amines. It is classified as a potential skin sensitizer.
