What it is
CI 47000 is a synthetic quinoline yellow dye. It is a petroleum-derived colorant that appears as a bright yellow powder or liquid, used to impart a yellow hue to cosmetic formulations.
How it works
In a cosmetic product, CI 47000 works by absorbing and reflecting specific wavelengths of light, making the product appear yellow. It is typically dissolved in oils or waxes to evenly distribute the color throughout the formula.
Pros
Vibrant color payoff
CI 47000 delivers a strong, bright yellow hue that stays true in lipsticks, blushes, and nail polishes, giving you consistent color every time.
Widely approved and tested
This dye is approved by regulators like the FDA and EU Commission, meaning it has undergone safety assessments for use in cosmetics.
Cons and cautions
Potential skin sensitivity
A small number of people may experience redness, itching, or irritation when using products containing this dye, especially on sensitive skin or around the eyes.
Not natural or eco-friendly
As a petroleum-derived synthetic colorant, it may not appeal to those seeking natural or sustainable beauty options, and its production has an environmental footprint.
Best for
- Anyone looking for a bright yellow color in their makeup
- People without known sensitivities to synthetic dyes
Use caution if
- Individuals with a known allergy or sensitivity to quinoline dyes
