D&C Orange No. 5 (Ci 45370)
What is D&C Orange No. 5 (Ci 45370)?
D&C Orange No. 5, denoted as CI 45370, is a synthetic organic colorant from the xanthene chemical class, specifically a brominated fluorescein derivative. It receives FDA certification for drug and cosmetic applications, ensuring high purity through batch testing. This water-soluble dye produces a bright orange hue, commonly incorporated into makeup items like lipsticks and blushes, bath soaps, shampoos, and nail enamels. In formulations, it disperses uniformly to deliver consistent pigmentation, either directly in solution or as an insoluble lake for oil-based products. This functionality supports stable, batch-uniform coloring that withstands processing and enhances product shelf-life appearance without altering texture.
