Applicant's summary and conclusion

Interpretation of results:
other: Not classified
Conclusions:
LD50 was considered to be > 5990 mg/kg bw when 4 male New Zealand albino rabbits were treated with Ethanol, 2.2’-(methylimino)bis- (MDEA) dermally
Executive summary:

In dermal toxicity study,4 male New Zealand albino rabbits were treated with Ethanol, 2.2’-(methylimino)bis- (MDEA) in the concentration of 5990 mg/kg bw dermally. No mortality observed in treated rabbits. Therefore, LD50 was considered to be > 5990 mg/kg bw when 4 male New Zealand albino rabbits were treated with Ethanol, 2.2’-(methylimino)bis- (MDEA) (105 -59 -9) by dermal application .
