D&C Red 27 Al Lake powder color (20g)

D&C Red No. 27 Al Lake (L07-2722) is an organic lake colorant that is derived from D&C Red No. 27, a synthetic azo dye, and is combined with aluminum hydroxide to form an insoluble pigment. This lake form of the colorant is used widely in cosmetics, personal care, pharmaceuticals, and food applications due to its excellent color stability, adherence, and safety profile.

The lake form is preferred in many applications because it offers better stability, colorfastness, and enhanced adherence compared to water-soluble dyes. As an insoluble pigment, it is ideal for use in solid, oil-based, and dry formulations, where vibrant, long-lasting color is needed.
