Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test item is not acute dermal toxic. The LD50 is > 5000 mg/kg bw.
Executive summary:

In the current study the acute dermal toxicity of the test item was assessed in rabbits. The study was not according to OECD and GLP was not specified.

The test material was applied to the skin of 10 rabbits. Mortality and systemic effects were observed over a period of 14 days. Gross necropsy was conducted on all animals. The dose used was 5000 mg/kg bw.

No animals died during the course of the study and no specific compound-related effects were observed. Therefore, the dermal acute LD50 is > 5000 mg/kg bw.
