Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute inhalation toxicity dose (LC50) value was considered to be >200 mg/L (>200000 mg/m3), when 10 rats were treated with test chemical by inhalation route for 1 hour exposure.
- Executive summary:
Acute inhalation toxicity study of test chemical was conducted in 10 rats at the dose concentration of 200 mg/L (200000 mg/m3) for 1 hour exposure. 1 out of 10 rats died within the 14 day-observation period. Therefore, LC50 value was considered to be>200 mg/L (>200000 mg/m3), when 10 rats were treated with test chemical by inhalation route for 1 hour exposure.
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.
