Already a 1 min exposure with ethylenediamine caused necrosis to the exposed skin.
The original BASF grading was converted into the numerical grading according the OECD Draize system.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1B (corrosive) based on GHS criteria
- Conclusions:
- Ethylene diamine is corrosive to rabbit skin
- Executive summary:
In a skin irritation/corrosion test, Vienna White rabbits were exposed to ethylene diamine.Two animals were treated for 1, 5 and 15 min using occlusive conditions. An application site of 2.5x2.5 cm was covered with the liquid test substance. After the application time the skin was washed with Lutrol (conc.) and Lutrol/water (1:1). The animals were observed for 14 days and skin changes were recorded daily. Ethylene diamine is corrosive to rabbit skin.
