Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
LD50 was considered to be >20000 mg/kg bw, when rabbits were treated with Ethyl vinyl ether (109-92-2) by dermal application.
Executive summary:

In an acute dermal toxicity study,rabbits were treated with Ethyl vinyl ether (109-92-2) at the concentration of 20000mg/kg bw. No mortality was observed at 20000 mg/kg bw. Therefore,LD50 was considered to be >20000 mg/kg bw, when rabbits were treated with Ethyl vinyl ether by dermal application.
