D&C Red 7 Ca Lake

Create bold, stable red cosmetic shades with D&C Red 7 Calcium Lake (CI 15850:1) — a high-performance FDA-certified lake pigment engineered for superior dispersion and long-lasting color payoff.

D&C Red 7 is converted into a lake pigment by precipitation onto a calcium substrate, transforming a soluble dye into an insoluble pigment. This structure prevents bleeding and enhances stability in wax and oil systems.

If you’re formulating lipsticks, blushes, or pressed powders, D&C Red 7 Ca Lake offers:

✔ Excellent oil dispersibility
✔ Strong tint strength
✔ Reduced migration in wax systems
✔ Consistent shade development
✔ FDA batch-certified regulatory compliance

It produces bright red to deep crimson tones depending on concentration and formulation base.
