Some classes of dyes, such as Azo dyes, are known to be toxic and carcinogenic. It is also used in pH regulators and water treatment products and may also be formed in the thermal degradation of MDI-based polyurethane and reactions in rubber industry. From the very early years of aniline dyes, muted, subdued aniline shades were made and sold, but it is much more difficult to identify garments made from aniline dyes in shades that could also be made from natural dyes. Aniline dyes were the first synthetically produced basic dyes.
