Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: other: CLP-Regulation (EC) No 1272/2008
- Conclusions:
- The median lethal dose (LD50) of 1,2-dichloro-1,1,2-trifluoro-2-(trifluoromethoxy)ethane is greater than 5000 mg/kg bw.
- Executive summary:
The IRI project No.238237, includes an acute oral toxicity test, an eye irritation test and a dermal irritation test.
In the acute oral toxicity test in rats, no deaths occurred and mild transient clinical signs were noted following a single oral dose of
1,2-dichloro-1,1,2-trifluoro-2-(trifluoromethoxy)ethane at a dose level of 5000 mg/kg bw (vehicle: corn oil).
The median lethal dose (LD50) of 1,2-dichloro-1,1,2-trifluoro-2-(trifluoromethoxy)ethane is greater than 5000 mg/kg bw.
