Description of key information
Uronium hydrogen sulphate is not considered to be harmful by oral or dermal route:
- Oral LD50 > 2000 mg/kg bw (rat)
- Dermal LD50 > 2000 mg/kg bw (rat, no mortality observed)
No data by inhalation is available. However there is a low potential for inhalation exposure. In addition, the substance has been demonstrated to be of low toxicity by dermal and oral routes of exposure. Dermal route is more appropriate as skin contact in production and/or use is likely. Testing for acute inhalation toxicity is therefore not justified on scientific grounds or based on exposure considerations.
Key value for chemical safety assessment
Additional information
Justification for classification or non-classification
Data are conclusive for oral and dermal route, but not sufficient for classification according to CLP criteria (Regulation (EC) No 1272/2008). No data is available by inhalation.
No classification is proposed for acute toxicity according to CLP.
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.
