It should be emphasized that the colorants that are commercially available as alternatives to FD&C
certified colorants are not stock commodities. Price is not the only variable to consider when selecting a given colorant. Colorants from different suppliers can vary in purity, tinctorial strength, shade of color, presence of unwanted flavors, tendency to precipitate, stability to heat and light, and their suitability for different applications. they need to be evaluated for their effectiveness in individual product formulations.
