D&C Yellow No. 10 (Ci 47005) Aluminum Lake

What is D&C Yellow No. 10 (Ci 47005) Aluminum Lake?

D&C Yellow No. 10 (CI 47005) Aluminum Lake is a synthetic insoluble pigment formed by adsorbing the quinoline-based dye Quinoline Yellow onto aluminum hydroxide substrate. This creates a vibrant, stable yellow colorant resistant to dissolving in water or oils, ideal for pigmentation in cosmetics. Primarily used in makeup like lipsticks, eyeshadows, and nail enamels, as well as soaps, shampoos, and hair dyes, it delivers consistent bright yellow hues. The lake structure ensures even dispersion, prevents color bleeding, and maintains shade uniformity during production and application. In hair formulations, it contributes to direct coloration or supports oxidative dyeing processes for effective shade achievement and coverage.
