E120-E129 Red

Food additive E128, also known as Red 2G, is a synthetic red azo dye that is banned for use in food because it poses serious health risks.

It is soluble in water and slightly soluble in glycerol.

It usually comes as a disodium salt of 8-acetamido-1-hydroxy-2-phenylazonaphthalene-3,6 disulfonate.

Red 2G is produced by azo coupling of Acetyl-H acid and diazonium derivative of Aniline under basic conditions.
