Besides its use in dyeing of natural fibers used in the Iranian hand-knotted Carpet, it is widely used in pharmaceutical, food, cosmetic, etc., and thus, it is considered as a FDC (Food, Drug, Cosmetic) natural colorant. It is also used as a reagent for identification of different metals through the formation of dye-metal complexes showing fluorescent and luminescent properties. In this paper, physical and chemical properties of cochineal as a natural dye as well as its extensive application in different industries have been reviewed.
