Additional information
Justification for classification or non-classification
- Acute toxicity: oral
Based on the LD50 of 91 mg/kg bw for female rats (oral route) a classification as category 3 / H301 is warranted.
- Acute toxicity: inhalation
Based on the LC50 of 0.338 mg/L per 4h inhalation of dust a classification as category 2 / H330 is warranted.
Furthermore, based on a pronounced irritation potential of the substance on the respiratory tract a classification as STOT SE category 3 / H335 (lung, inhalation) is warranted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
