Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the test conditions, the oral LD50 is higher than 2000 mg/kg bw in rats, therefore the substance is not classified according to CLP Regulation (EC) No. 1272 /2008.
- Executive summary:
Test Guidance
OECD Guideline 420 and EC Method B.1 bis (Acute Oral Toxicity - Fixed Dose Procedure)
Method and materials
Following a sighting study at the dose level of 2000 mg/kg bw, an addition 4 fasted female Wistar rats (RccHan™:WIST) were given a single oral (gavage) dose of the test material at 2000 mg/kg bw. Animals were then observed for mortality, clinical signs and bodyweights for 14 days and were all sacrificed for macroscopic examination.
Results
No mortality was observed. No signs of systemic toxicity were noted during the observation period. All animals showed expected gains in body weight over the observation period. No abnormalities were observed at necropsy. In this study, the oral LD50 of the test item was considered to be higher than 2000 mg/kg bw in female rats.
Conclusion
Under the test conditions, the oral meadian LD50 is higher than 2000 mg/kg bw in female rats, therefore the substance is not classified according to CLP Regulation (EC) No. 1272 /2008.
