Applicant's summary and conclusion

Interpretation of results:
other: Not acute toxic
Remarks:
in accordance with EU CLP (EC 1272/2008 and its updates)
Conclusions:
The oral LD50 value of Cedrenol in rats was established to be higher than 5000 mg/kg bw, under the conditions of this study.
Executive summary:

The acute toxic potential of Cedrenol was assessed in an acute oral toxicity limit test performed similar to OECD TG 401. Ten rats were exposed to 5000mg/kg bw Cedrenol via the oral route, and observed for clinical signs and mortality over an examination period of 14 days. Daily observations were performed. At the end of the study period no mortality was observed in any of the animals. Furthermore no symptoms occured in the test animals. Based on these results the LD50 for acute oral toxicity was set at > 5000 mg/kg bw.
