CI 19140 (FD&C Yellow 5)
What is CI 19140 (FD&C Yellow 5)?
CI 19140, also known as FD&C Yellow 5 or Tartrazine, is a synthetic lemon yellow azo dye primarily used in food, beverages, and cosmetics to provide a bright yellow color. It is manufactured from petroleum products through a chemical process.
This coloring is used because it is stable under various conditions and provides a vivid color that appeals to consumers. Some studies have linked Tartrazine to hyperactivity in children, but the evidence is not consistent. It may also cause allergic reactions in a small number of individuals, particularly those with aspirin sensitivity.
When you see CI 19140 on a label, know that it is approved for use in many countries but often scrutinized due to potential health effects, leading to calls for clearer labeling.
Commonly found in: Soft drinks, Candies, Baked goods, Cereals, Cosmetics, Pharmaceuticals

Scout's take
Coal-tar azo dye (Tartrazine) added for bottle color. Frequent contact-sensitizer in topical products; aesthetic-only addition. FDA-banned in foods in California (2024) for behavioral effects.
