What it is
CI 69800 is a synthetic organic dye from the anthraquinone family, also known as Acid Violet 43 or D&C Violet No. 2. It is produced through chemical synthesis and is used to color cosmetics.
How it works
In a cosmetic product, CI 69800 dissolves or disperses evenly to impart a violet color. It does not interact with skin biology; its role is purely aesthetic, helping products look appealing or match a desired shade.
Pros
Vibrant color
Provides a bright, consistent violet shade that doesn't fade easily in most formulations.
Regulatory approval
Approved by the FDA and EU for use in cosmetics, with a long history of safe use at low concentrations.
Cons and cautions
No skin benefit
This ingredient adds only color; it does not moisturize, protect, or treat the skin in any way.
Potential staining
In higher concentrations or in certain formulations, it may temporarily stain skin or fabrics, which can be inconvenient.
Best for
- Anyone who wants colorful cosmetic products
- People looking for a stable, long-lasting dye in hair color or bath products

- Individuals with known allergies to synthetic dyes (rare)
