Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging CI 58000.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

low

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

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

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

What it is

CI 58000 is a synthetic organic pigment from the monoazo class, specifically a calcium salt of a sulfonated azo dye. It is produced through chemical synthesis and is not found in nature.

How it works

In cosmetics, CI 58000 works by depositing a thin layer of colored particles on the skin or nails. It is insoluble in water and most oils, which helps it stay put and resist smudging or fading throughout the day.

Pros

Vibrant color payoff

CI 58000 delivers a strong, true red hue that stays consistent across batches, making it a favorite for bold lipsticks and blushes.

Good stability

This pigment resists fading from light and heat, so your makeup keeps its color longer during wear and storage.

Cons and cautions

Potential irritant for sensitive skin

A small percentage of people may experience redness or stinging when using products with CI 58000, especially on compromised skin.

Environmental footprint

As a synthetic azo dye, its production involves chemicals that can be harmful to the environment if not properly managed.

Best for

  • Anyone looking for bold, long-lasting red shades in makeup
  • People without known sensitivities to synthetic colorants

Use caution if

  • Individuals with known allergies or sensitivities to azo dyes or synthetic pigments

Usage tips

Always patch test a new product containing CI 58000 on your inner arm before applying to your face or lips.
If you have sensitive skin, look for products that list CI 58000 lower on the ingredient list, indicating a lower concentration.

Safety summary

CI 58000 is considered safe for cosmetic use at regulated levels by major health authorities. However, it may cause mild irritation in sensitive individuals, and patch testing is recommended.

Research notes

Studies indicate that CI 58000 has low acute toxicity and is not a significant skin sensitizer for the general population. Long-term safety data is limited but no major concerns have been identified at typical use levels.
