Acid Blue 74 Aluminum Lake
What is Acid Blue 74 Aluminum Lake?
Acid Blue 74 Aluminum Lake is an insoluble pigment created by adsorbing the synthetic azo dye Acid Blue 74 (CI 43825) onto aluminum hydroxide substrate. This process converts the water-soluble dye into a stable, non-migrating colorant ideal for cosmetic applications. Primarily used in color cosmetics such as lipsticks, eyeshadows, blushes, and nail enamels, it delivers a bright blue shade. In formulations, the lake disperses evenly without dissolving, ensuring color uniformity, resistance to fading from light or friction, and consistency across product batches. Its particulate nature allows for smooth application and long-lasting visual effects on the skin.
