Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A highly toxic, volatile nitrile compound used primarily in industrial polymer synthesis. It is a known human carcinogen and is prohibited or severely restricted in cosmetic products.
Acrylonitrile (CH2=CH-CN) is a highly reactive unsaturated nitrile monomer used primarily in the synthesis of acrylic fibers, plastics, and synthetic rubber. It is classified as a known human carcinogen (IARC Group 1, confirmed animal carcinogen, suspected human carcinogen). It is readily absorbed through the skin and is a potent skin sensitizer. EU regulations severely restrict its presence in mixtures (≥0.1% triggers restrictions) and prohibit its use as a propellant in aerosols. It has absolutely no cosmetic benefit.
