Citrus Red 2, Citrus Red No. 2, C.I. Solvent Red 80, or C.I. 12156 is an artificial dye. As a food dye, it is permitted by Food and Drug Administration (FDA) since 1956 only for use in the United States to color the skin of oranges.[1][2][3][4] Citrus Red 2 is listed as an IARC Group 2B carcinogen, meaning that it is "possibly carcinogenic to humans".[5] However, it does not penetrate the orange peel into the pulp.[citation needed]
