About

3-methyl-5-phenyl-2-pentenenitrile is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This unsaturated nitrile carries multiple hazard classifications including H302 (acute toxicity upon ingestion), H317 (skin sensitization), and H412 (aquatic toxicity with long-lasting effects). The nitrile functional group introduces additional toxicological concern beyond typical fragrance materials. EU REACH and cosmetic regulation treat substances with combined acute toxicity and sensitization warnings as requiring special formulation care, with allergen disclosure and possible concentration restrictions applicable to this ingredient.

Known concerns

  • skin sensitizer (H317)
  • acute toxicity (H302)
  • aquatic hazard (H412)
