| General description: | o-Aminoazotoluene (AAT) is categorized as a Class 2B carcinogen by the international agency for research on cancer (IARC). This class of azo dyes are widely used as colorants in a variety of products including leather, cosmetics, paper, toys, plastics, pharmaceuticals, textiles, paints, food, leather, etc. Primary aromatic amines (PAAs) are most commonly used as starting compounds in the production of azo dyes and can often migrate into foodstuffs from food packaging materials. AAT finds applications in coloring oils, fats, and waxes. |
