E104 is a food additive approved by the European Union (EU). It is used as a synthetic colouring agent in food and drink products, as well as in cosmetics.
The common name for E104 is Quinoline Yellow.
E104 is highly water soluble. It is also used in cosmetics such as hair products, lipsticks and perfumes, as well as a wide variety of foods.
E104 is banned (for certain uses) in the United States, Australia and Norway because it is believed to have caused dermatitis (inflammation of the skin).
Examples of food and drink products that may include E104:
- smoked fish
- scotch eggs
- ice lollies
