Applicant's summary and conclusion

Interpretation of results:

other: Not classified

Remarks:

based on CLP criteria (Annex I of 1272/2008/EC)

Conclusions:

The oral LD50 value of Ylang oil Extra in rats was established to be higher than 5000 mg/kg bw, under the conditions of this study. The substance therefore does not need to be classified according to the classification criteria outlined in Annex I of the CLP Regulation 1272/2008/EC.

Executive summary:

A single 5000 mg/kg bw dose of Ylang oil Extra was administered by oral gavage to 10 male Wistar rats. The animals were observed for 14 days. No mortality was noted. Coma and chromodacryorrhea were observed 24 hours post-treatment, effects that could no longer be detected 48 hours after treatment.The oral LD50 value for Ylang oil Extra 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 outlined in Annex I of the CLP Regulation (1272/2008/EC).
