Applicant's summary and conclusion

Interpretation of results:
other: not classified
Remarks:
based on CLP criteria
Conclusions:
The dermal LD50 of Cedarwood Virginia were determined to be higher than 5000 mg/kg bw. Based on the available information, the test substance does not need to be classified for acute dermal toxicity, according to the classification criteria outlined in Annex I of 1272/2008/EC (CLP).
Executive summary:

In this limit test, a high dose of 5000 mg.kg bw Cedarwood Virginia was applied dermally to the skin of 9 rabbits. The rabbits were observed for 14 days. No mortality was observed, and the LD50 was established to be higher than 5000 mg/kg bw. Based on the available information, the test substance does not need to be classified for acute dermal toxicity, according to the classification criteria outlined in Annex I of 1272/2008/EC (CLP)
