Where can I obtain powdered food coloring for use in compounding?
Food coloring as a descriptive class is not approved for use in pharmaceutical compounding; however, drug and cosmetic (D&C) and food, drug, and cosmetic (FD&C) dyes are allowed. Colorants are unique compounds from a legislative and regulatory standpoint: most countries maintain positive lists of colorants suitable for use in food, drugs, cosmetics, or in more than 1 of these classes.
Following are several examples of FD&C colorants approved for use in the United States. Please note: Where the words Alum Lake are used, the dye is insoluble; in compounded preparations it is used most often as an excipient in capsule formulations as a visual aid to verify uniformity. The other dyes are water-soluble. Either type can be used to make a preparation more appealing to the patient and hence improve adherence.
Examples of Approved Colorants
*Tartrazine-containing prescription drugs for human use are required to bear the statement: "This product contains FD&C Yellow #5 (tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons."
The incidence of this sensitivity in the general population is low, but aspirin-sensitive patients seem most likely to exhibit tartrazine hypersensitivity.
