Synthetic quinoline dye — recognised contact sensitiser; restricted in cosmetics

EU cosmetic rules restrict it to rinse-off products and bar it from anything applied to mucous membranes or the eye area. It is a colourant only: it delivers no benefit to the formulation.

Method and limits
- Prevalence counts published products whose decoded ingredient list matches this substance or one of its label synonyms, using the same matching the score itself uses. It describes our catalogue of 893 products, not the Indian market as a whole.
- Presence is not dose. An ingredient list gives order, not quantity, unless the pack declares a percentage. Nothing here estimates how much of this substance any product contains.
- A classification is not a verdict on a product. An agency classifies a substance under defined conditions of exposure; whether that matters in a given food or cosmetic depends on route, concentration and use.
