  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

CI 18130 is a synthetic organic pigment classified as a monoazo pigment. It is produced through chemical synthesis and is not found in nature. It is part of the Color Index (CI) system used to standardize colorants globally.

How it works

In a cosmetic product, CI 18130 is dispersed as fine particles that reflect and absorb specific wavelengths of light, giving the product a red hue. It does not react with skin or change color after application.

Pros

Vibrant color

Provides a strong, consistent red shade that doesn't fade easily in light or heat.

Low irritation risk

Generally well-tolerated by most skin types, with very low reported rates of irritation or allergy.

Cons and cautions

No skincare benefit

This ingredient is purely cosmetic—it adds color but does not hydrate, protect, or improve skin health.

Potential staining

If not properly formulated, the pigment can transfer and stain clothing or skin, especially in lip or cheek products.

Best for

  • Anyone looking for a red pigment in makeup
  • People who prefer synthetic over natural colorants

Use caution if

  • Individuals with known sensitivity to synthetic colorants (very rare)

Usage tips

Use in well-formulated products to minimize transfer and staining.
Patch test if you have a history of sensitivity to synthetic dyes.

Safety summary

CI 18130 is considered safe for cosmetic use by major regulatory agencies when used as intended. Rare cases of skin sensitivity have been reported, but it is generally non-irritating and non-comedogenic.
