Yellow 6

Yellow 6 is a synthetic food dye, also known as Sunset Yellow FCF, with the chemical formula C16H10N2Na2O7S2. It is one of the food colorings approved by the FDA for use in food and drug products.

History

Yellow 6 was first synthesized in the late 19th century as part of a class of compounds known as azo dyes. These dyes were initially used in the textile industry, but their use quickly spread to other industries, including the food industry.

Production

The production of Yellow 6 involves the reaction of sulfanilic acid with sodium nitrite in the presence of hydrochloric acid to form a diazonium salt. This salt is then coupled with 2-naphthol-6-sulfonic acid to form the final product.

Uses

Yellow 6 is widely used in the food industry to give products a bright, appealing color. It is commonly found in products such as candy, baked goods, soda, gelatin desserts, and sauces. It is also used in cosmetics and pharmaceuticals.

Health Effects

There has been some controversy over the safety of Yellow 6. Some studies have suggested a possible link between the dye and hyperactivity in children, while others have found no such link. The FDA continues to monitor the safety of Yellow 6 and other food dyes.

Regulation

In the United States, the use of Yellow 6 in food products is regulated by the FDA. The European Union also regulates the use of Yellow 6, where it is listed as E number E110.
