FD&C Red No 3

Erythrosine is an organoiodine compound and a derivative of fluorone used as a red-pink dye in various industries, including food coloring, cosmetics, and industrial applications. It was first discovered in 1876 and commercialized for dyeing wool and silk, and its use as a food dye was legalized in the US by the Pure Food and Drug Act of 1906. However, due to concerns over its potential carcinogenic effects, its use has been restricted in various countries, including the European Union, United States, Canada, and Australia/New Zealand, and it has been banned in the US since 1990, with a final ban on all food uses effective in 2027.learn more on wikipedia
