Score terms in plain English
Irritation risk

What it is
Disperse Violet 1 is a synthetic organic dye from the anthraquinone chemical family. It is a fine powder that is insoluble in water and used to impart a violet color to various cosmetic formulations.
How it works
In a cosmetic product, Disperse Violet 1 works by absorbing certain wavelengths of visible light and reflecting others, which our eyes perceive as violet. It is dispersed (finely distributed) throughout the product base to create an even color.
Pros
Bright color payoff
Provides a strong, consistent violet shade that is hard to achieve with natural colorants alone.
Good stability
Remains color-stable in most cosmetic formulations, including those with varying pH or exposure to light.
Cons and cautions
Irritation potential
Can cause skin irritation or allergic reactions, especially on sensitive areas like the scalp or around the eyes.
Staining risk
May temporarily stain skin, nails, or fabrics, which can be difficult to remove.
Best for
- People who want colorful, vibrant cosmetics
- Those without known sensitivity to synthetic dyes
Use caution if
- Individuals with sensitive skin or a history of allergic reactions to hair dyes or textile dyes
Usage tips
Safety summary
Disperse Violet 1 is generally considered safe for most people at low concentrations, but it is a known allergen for some individuals. The EU Scientific Committee on Consumer Safety (SCCS) has noted that it can cause skin sensitization. It is best avoided by those with known dye allergies.
Research notes
Research indicates that Disperse Violet 1 can cause allergic contact dermatitis, particularly in individuals already sensitized to disperse dyes. Studies show it has low acute toxicity but moderate skin irritation potential. More research is needed on long-term low-dose exposure.
Common label clues
- Typical concentration
- Very low, typically less than 1%
- Regulatory status
- Approved for use in cosmetics in the EU and US, but subject to concentration limits and labeling requirements. In the EU, it is listed in Annex IV (allowed colorants).
- Common uses
- Hair dye, Nail polish, Soap, Bath products
- Environmental note
- As a synthetic dye, it is not biodegradable and may persist in water systems if not properly filtered during manufacturing.
Good to know
- Disperse Violet 1 is also used in textile dyes, so people with textile dye allergies may react to it in cosmetics.
- It is often listed on labels as 'CI 61100' or 'Disperse Violet 1'.
