D&C Red 21 Lake

Achieve vibrant pink-to-red tones in oil-based cosmetic systems with D&C Red 21 Lake Powder (CI 45380:2) — a high-performance, FDA-certified lake pigment engineered for professional cosmetic and pharmaceutical formulations.

Unlike water-soluble dyes, D&C Red 21 is supplied in lake form, meaning the dye is precipitated onto an insoluble substrate (typically calcium salt). This makes it insoluble in water but easily dispersible in oils, waxes, and hydrophobic cosmetic bases.

If you’re developing lipsticks, balms, or cream cosmetics, D&C Red 21 delivers:

✔ Excellent oil dispersion
✔ Strong tint strength
✔ Reduced color bleeding
✔ High shade stability
✔ FDA batch-certified compliance

It produces bright pink to red shades depending on concentration and formulation environment.
