D&C Yellow No. 11 (Ci 47000)
What is D&C Yellow No. 11 (Ci 47000)?
D&C Yellow No. 11, also designated CI 47000 or Quinoline Yellow, is a synthetic organic colorant from the quinoline family. It features sulfonated quinophthalone structures, yielding a bright greenish-yellow shade. Commonly incorporated into makeup like lipsticks, eyeliners, nail polishes, and bath preparations, it serves as a colorant by uniformly dispersing in oil or water-based formulas. This ensures stable pigmentation that maintains hue during application and wear, aiding manufacturers in achieving reproducible visual effects. As a certified batch color additive, it meets purity standards set by regulators, distinguishing it from uncertified pigments. Its solubility properties allow integration without altering texture, focusing solely on aesthetic enhancement in rinse-off and leave-on cosmetics.
