The Research Institute for Fragrance Materials (RIFM) has conducted a peer-reviewed safety assessment, concluding its safe use under current levels. The International Fragrance Association (IFRA) limits its concentration to 20.00% in fine fragrances (Category 4). Despite these assessments, it is classified as an irritant (Xi), indicating potential irritation to eyes, respiratory system, and skin (R 36/37/38), and causes serious eye irritation (H319).
