Different azo dyes are widely used in textile, printing, cosmetic, drug and food processing industries. Metanil Yellow, a monosodium salt of 3-[[4-(Phenylamino) phenyl] azo] benzenesulfonic acid is one among those. It is a non-permitted food colour as well as an additive. Azo dyes are also used in laboratories as biological indicators or as pH indicators. There are varieties of food additives, ...

The question of whether food additives such as preservatives, artificial flavorings, and artificial colorings trigger hyperactivity has been debated for more than 30 years. Research generally has not supported food additives as influencing hyperactivity—whose characteristics include overactivity, inattention, and impulsive behaviors, traits that in extreme forms define attention deficit/hyperac...
