FD&C Yellow 5 (Ci 19140)
What is FD&C Yellow 5 (Ci 19140)?
FD&C Yellow 5, also called tartrazine or CI 19140, is a synthetic azo compound created via chemical processes like diazotization of sulfanilic acid coupled with hydrazine derivatives. Certified by the FDA for cosmetics, it appears as a vivid yellow powder highly soluble in water. Commonly incorporated into shampoos, lotions, soaps, makeup, and nail products, it acts as a colorant by absorbing certain light wavelengths to reflect yellow tones, ensuring uniform pigmentation. This stability helps products retain their hue during storage and use, outperforming some natural alternatives in consistency and intensity. Regulatory assessments confirm its role in enhancing visual product quality without altering other formulation properties.
