What it is

A synthetic organic pigment from the azo dye family, specifically a calcium salt of a red dye. It's listed as D&C Red No. 6 in the U.S. and is used to create bright red and pink shades.

How it works

It works by reflecting red wavelengths of light and absorbing others, imparting color to the product. It is insoluble in water, so it stays suspended in the formula and doesn't bleed or migrate.

Pros

Vibrant color payoff

Delivers intense red and pink hues that stay true in lipsticks and blushes, giving you a bold look with minimal product.

Good stability

Resists fading and bleeding in formulas, so your makeup stays looking fresh longer without smudging or migrating.

Cons and cautions

Potential irritation

A small number of people with very sensitive skin may experience redness or stinging, especially on the lips or around the eyes.

Not natural

As a synthetic pigment, it doesn't appeal to those who prefer naturally derived colorants like iron oxides or plant extracts.

Best for

  • Anyone looking for bold red or pink makeup shades
  • Those who tolerate standard synthetic colorants well

Use caution if

  • Individuals with known sensitivity to azo dyes or red pigments
  • Those seeking exclusively natural or plant-based ingredients

Usage tips

If you have sensitive skin, patch test a product containing this pigment on your inner arm before using it on your face or lips.
Pair with a lip balm or primer if using in lip products to reduce direct contact with sensitive lip skin.

Safety summary

Generally considered safe for cosmetic use at typical concentrations, with low irritation and allergy risk for most people. However, those with a history of sensitivity to azo dyes should exercise caution.

Research notes

Studies confirm low acute toxicity and skin irritation potential, but some individuals may experience allergic contact dermatitis. Regulatory bodies like the FDA and EU SCCS have set safe usage limits.
