Tartrazine, also known as FD&C Yellow #5 or E102, is a synthetic lemon-yellow azo dye used to add a vivid color to a wide variety of commercial products. Manufacturers favor it for its stability and affordability. While regulatory bodies like the FDA and EFSA approve its use, a small number of people are sensitive to it, and some studies suggest potential links to behavioral issues in children. Its widespread use means it appears in products from numerous brands across various industries.
Understanding Tartrazine

Its use extends beyond food and beverages to cosmetics, pharmaceuticals, and household products. Knowing its different names and how it appears on labels is important for consumers, particularly those with sensitivities.
