Applicant's summary and conclusion

Interpretation of results:
Toxicity Category III
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
LD50 in an acute dermal toxicity test on rabbit was 560 mg/kg.
Executive summary:

Rabbits were exposed to concentrated ethylene diamine (76%) and a 10% dilution in water under occlusive coverage for 24 h. With the concentrated substance, severe skin damage occurred. Congestion of the lungs and damage to the abdominal organs was noted on autopsy. LD50 was 560 mg/kg bw. For the diluted samples LD50 was approximately 1520 mg/kg bw.
