Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

About

A synthetic dye with clear regulatory problems. This is not a good ingredient to see in a compliant cosmetic formula.

This ingredient is a synthetic dye or colorant with an EU Annex II listing, which means it is prohibited in cosmetic products in the EU. Hazard data also point to irritation or other toxicology flags, so it should not be treated like a normal low-risk color additive. A banned dye should score near zero even if it once had technical use in hair products.

Function

Known concerns
