Applicant's summary and conclusion

Interpretation of results:
other: not classified
Remarks:
based on CLP Regulation (1272/2008/EC)
Conclusions:
The oral LD50 value of Gurjon oil in rats was established as exceeding 5000 mg/kg body weight, under the conditions of this study. The substance therefore does not need to be classified according to the classification criteria outlined in CLP Regulation 1272/2008/EC (CLP).
Executive summary:

A single 5000 mg/kg bw dose of Gurjon oil was administered by oral gavage to 10 male Wistar rats. The animals were observed for 14 days. No symptoms or mortality were noted. The oral LD50 value of Gurjon oil in rats was established as exceeding 5000 mg/kg body weight, under the conditions of this study. The substance therefore does not have to be classified according to the classification criteria of the CLP Regulation 1272/2008/EC.
