Red 28 Lake (also known as Phloxine B aluminum lake) is an insoluble pigment form of the synthetic dye Red 28, used to impart red coloring in cosmetics such as lipsticks, blushes, and nail products. It is a lake, meaning the dye is bound to an insoluble metal substrate for greater stability and reduced bleeding.
