Administration / exposure

Route of administration:

oral: gavage

Vehicle:

water

Doses:

300 and 2000 mg/kg bw

No. of animals per sex per dose:

Results and discussion

Effect levels

Sex:

female

Dose descriptor:

LD50

Effect level:

> 300 - < 2 000 mg/kg bw

Mortality:

All animals of the 300 mg/kg bw dose group survived.
All animals of the 2000 mg/kg bw dose group died within hour 0 after administration.

Clinical signs:

other: Clinical observation in the 2000 mg/kg bw test group revealed poor general state, pronounced dyspnoea, piloerection and salivation in all three animals. Additionally, one animal showed clonic convulsions and respiration noises. In the first 300 mg/kg test

Gross pathology:

The following macroscopic pathologic findings were observed in all animals that died in the 2000 mg/kg bw test group: Severe swelling of the
stomach mucosa, dark red discoloration of the stomach content, extensive bleeding in the glandular stomach and forestomach, dark red
discoloration of the small intestine and its content, spotted discoloration of the liver and congestion in the kidneys.
There were no macroscopic pathological findings in the animals sacrificed at the end of observation period (300 mg/kg bw: 6 females).

Applicant's summary and conclusion

Interpretation of results:

harmful

Remarks:

Migrated information Criteria used for interpretation of results: OECD GHS

Conclusions:

Under the conditions of this study the median lethal dose of Aminopropyl Vinyl Ether after oral administration was found to be greater than 300 mg/kgbw and less than 2000 mg/kg bw in rats.
Based on the results of this study, the test substance has to be classified Acute Tox Cat 4 (Directive 1272/2008 of CLP) and R22 (67/548/EWG).
