Applicant's summary and conclusion

Interpretation of results:
other: Not classified
Remarks:
Based on the CLP Regulation (1272/2008/EC).
Conclusions:
The dermal LD50 value of Cedarwood Texas Oil in rabbits 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 annex 1 of CLP Regulation 1272/2008/EC (CLP).
Executive summary:

10 Rabbits were dermally exposed to 5000 mg/kg bw dose of Cedarwood Texas Oil. The animals were observed for 14 days. No symptoms or mortality were noted. The dermal LD50 value of Cedarwood Texas Oil in rabbits was established as exceeding 5000 mg/kg body weight, under the conditions of this study.
