Applicant's summary and conclusion

Interpretation of results:
other: not classified
Remarks:
Criteria not met according to EU CLP 1272/2008 and its amendments.
Conclusions:
Under the conditions of this study, the acute oral LD50 for the substance in male and female rats was determined to be >2000 mg/kg bw. Based on this result, the test material does not need to be classified for acute oral toxicity in accordance with the criteria outlined in Annex I of the CLP Regulation (1272/2008/EC) and its amendments.
Executive summary:

In the acute oral toxicity study, performed according to OECD guideline 401, 10 rats (5 males and 5 females) were administered the substance at a dose level of 2000 mg/kg bw by oral administration. Under the test conditions the test animals revealed neither toxic symptoms nor mortality. No body weight or macroscopical abnormalities were detected. The acute oral LD50 for the substance in male and female rats was determined to be >2000 mg/kg bw. Based on this result, the test material does not need to be classified for acute oral toxicity in accordance with the criteria outlined in Annex I of the CLP Regulation (1272/2008/EC) and its amendments.
