FD and C Red No. 40
Description FD and C Red No. 40, also known as Allura Red, is a synthetic dye commonly used as a pharmaceutical excipient to impart a red color to tablets, capsules, liquid medications, and other dosage forms. Its primary role is to enhance the visual appeal and brand recognition of pharmaceutical products, making them more identifiable and visually distinct, which can aid in patient compliance. As an excipient, FD and C Red No. 40 is not intended to have any therapeutic effects; rather, it aids in the aesthetic and functional aspects of drug formulation. It is widely used due to its stability, solubility, and safety profile when used within regulated limits set by health authorities.
