CI 77220
INCI: CI 77220
A safe, widely used red pigment that gives color to makeup without known skin irritation or clogging pores.
In plain English
CI 77220 is a red iron oxide pigment. It's a mineral-based colorant that's been used for decades in makeup like lipstick, blush, and eyeshadow. It's considered very safe for most people because it sits on the skin's surface and doesn't penetrate deeply. It's not known to cause breakouts or irritation, making it a common choice for sensitive skin formulas.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging CI 77220.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

What it is
CI 77220 is a synthetic red iron oxide pigment. It's a fine powder that provides a stable, vibrant red color. It's part of a family of iron oxide pigments (including yellow, black, and brown) that are commonly used in cosmetics.
How it works
In a cosmetic product, CI 77220 particles reflect and absorb light to create a red color. It's mixed into the product base (like a cream or powder) and stays on the skin's surface, providing color without being absorbed. It's chemically stable, meaning it doesn't fade or change color easily under normal use.
Pros
Very safe for skin
Iron oxides are among the most thoroughly tested cosmetic pigments. CI 77220 has a low irritation and allergy risk, even for sensitive skin types.
Won't clog pores
This pigment is non-comedogenic, meaning it won't block pores or contribute to acne breakouts, making it ideal for foundation and blush on acne-prone skin.
Cons and cautions
Can stain fabrics
Red iron oxide can leave stubborn stains on clothing, towels, or pillowcases if not washed promptly. Use a makeup remover or pre-treat stains.
Synthetic origin
Some consumers prefer natural colorants. CI 77220 is synthetically produced, though it's chemically identical to naturally occurring iron oxide.
Best for
- Anyone looking for a safe, non-irritating red pigment in makeup
- People with sensitive skin or acne-prone skin who want color without breakouts
Use caution if
- Those with a known allergy to iron oxides (extremely rare)

Research notes
Iron oxides have been extensively studied for safety in cosmetics. The Cosmetic Ingredient Review (CIR) panel has concluded that iron oxides are safe for use in cosmetics at current concentrations. No significant health concerns have been identified.
Common label clues
- Typical concentration
- 0.1% to 10% depending on desired shade intensity
- Regulatory status
- Approved by the U.S. FDA as a color additive for cosmetics, including eye area use. Also permitted in the EU and other major markets.
- Common uses
- Lipsticks, Blushes, Eyeshadows, Foundations, Nail polishes
- Environmental note
- Iron oxide pigments are generally considered low environmental impact, but synthetic production does involve mining and chemical processing. Some brands source from certified sustainable suppliers.
Good to know
- CI 77220 is approved by the FDA for use in cosmetics, including eye area products.
- It's often combined with other iron oxides (yellow, black) to create a wide range of skin-tone shades.
