  • Applications

    Used primarily as a cosmetic color additive under D&C rules (D&C Red No. 30; CAS 2379-74-0). In practice, common applications include colorants for cosmetics and personal care products such as lipstick, lip balms, eye makeup, and nail polishes; it may also be employed in coatings and printing inks for packaging to achieve a stable red hue; in polymers and plastics, it can serve as a colorant additive for molded parts and films; and it is sometimes evaluated for colorant formulations in specialty coatings and industrial pigments.
