In plain English

What it is

CI 10006 is a synthetic inorganic pigment, specifically a chromium oxide green, that is approved for use in cosmetics in many regions. It provides a stable, opaque green color that doesn't fade easily.

How it works

It works by reflecting green wavelengths of light and absorbing others. When mixed into a cosmetic base, it evenly disperses to create a uniform color. It does not interact with skin biology.

Pros

Vibrant and stable color

CI 10006 delivers a rich green hue that resists fading from light or heat, so your makeup stays true to color.

Low irritation risk

It is generally non-irritating and non-comedogenic, making it suitable for most skin types, including sensitive skin.

Cons and cautions

No skincare benefit

This pigment does nothing for your skin—no hydration, anti-aging, or protection. It's purely cosmetic.

Potential for staining

If not properly formulated or removed, it can temporarily stain skin or clothing, especially in high-concentration products.

Best for

  • Anyone looking for green-tinted makeup or bath products
  • People who want a stable, non-fading color in their cosmetics

Use caution if

  • Those seeking skincare benefits from their color products
  • Individuals with known sensitivity to chromium compounds (rare)

Usage tips

Always remove green makeup thoroughly with a gentle cleanser or makeup remover to avoid any temporary staining.
Patch test a new product containing this pigment if you have very sensitive skin, though reactions are rare.
