CI 45410 (D&C Red No. 27 Or 28) Lake
What is CI 45410 (D&C Red No. 27 Or 28) Lake?
CI 45410, also called D&C Red No. 27 or 28 Lake, is a manufactured pigment created by combining a synthetic fluorescent dye—typically a chlorinated derivative of fluorescein—with an insoluble base like aluminum hydroxide or calcium salt. This process forms a water-insoluble lake that delivers bright red shades without dissolving or migrating in formulations. Primarily featured in color cosmetics such as lipsticks, blushes, eyeshadows, and nail enamels, it functions by dispersing evenly to provide uniform pigmentation and visual appeal. Regulatory agencies certify batches for purity, controlling impurities like heavy metals and ensuring consistency. Its particulate nature limits solubility, aiding stability across pH ranges and during product use.
