D&C Red 21 Aluminum Lake

Formulate vibrant pink-to-red cosmetic shades with precision using D&C Red 21 Aluminum Lake (CI 45380:3) — a high-performance, FDA-certified lake pigment engineered for stability, dispersion control, and professional-grade color payoff.

Unlike water-soluble dyes, aluminum lake pigments are created by precipitating the dye onto an aluminum substrate. This produces an insoluble pigment that disperses uniformly in oils, waxes, and anhydrous cosmetic bases without bleeding or migration.

If you’re manufacturing lipsticks, pressed powders, or cream-based cosmetics, D&C Red 21 Aluminum Lake provides:

✔ Excellent oil dispersion
✔ Superior color stability
✔ Reduced bleeding in wax systems
✔ High tint strength
✔ FDA batch-certified regulatory compliance

Depending on formulation concentration, it delivers bright pink to rich red tones.
