What it is
CI 15985 is a synthetic azo dye derived from petroleum. It is part of the FD&C color family and is certified by the FDA for use in cosmetics, drugs, and foods. In cosmetics, it appears as a yellow-orange powder that is water-soluble.
How it works
It works by absorbing and reflecting specific wavelengths of light, giving the product a yellow-orange hue. It does not provide any skincare benefits; its sole purpose is aesthetic.
Pros
Vibrant and stable color
Provides a consistent, bright yellow-orange shade that doesn't fade quickly, making it reliable for lipsticks, blushes, and eyeshadows.
Cost-effective
Much cheaper than many natural colorants, keeping product prices lower for consumers.
Cons and cautions
Potential allergen
A small percentage of people may experience contact dermatitis or irritation, especially if they have a history of reactions to synthetic dyes.
Not natural or sustainable
Derived from petroleum, which may be a concern for those seeking eco-friendly or clean beauty products.
Best for
- Anyone looking for affordable, vibrant color in makeup
- People without known sensitivities to synthetic dyes
Use caution if
- Individuals with known allergies to azo dyes or sensitive skin prone to irritation
Usage tips
Safety summary
CI 15985 is considered safe for cosmetic use at approved concentrations by major regulatory agencies. However, it may cause allergic reactions in sensitive individuals. There is no strong evidence linking topical use to serious health risks.
Research notes
Studies on CI 15985 focus mainly on oral ingestion and hyperactivity in children; topical safety data is limited but generally supports low irritation risk. The Cosmetic Ingredient Review (CIR) panel has reviewed similar azo dyes and found them safe in cosmetics at current usage levels.
Common label clues
- Typical concentration
- Very low, typically less than 1%
- Regulatory status
