Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- LD50 was considered to be >15000 mg/kg bw when 10 Wistar II female rat was treated with Benzenesulfonic acid,2-2’-(1,2-ethenediyl)bis(5-((4-(bis(2- hydroxyethyl)amino)-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-, free acid orally by gavage.
- Executive summary:
In a acute oral toxicity study, 10 Wistar II female rat was treated with Benzenesulfonic acid,2-2’-(1,2-ethenediyl)bis(5-((4-(bis(2- hydroxyethyl)amino)-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-, free acid in the concentration of 15000 mg/kg bw orally by gavage in water (3 % solution). No mortality and clinical signs were observed in treated female rat at 15000 mg/kg bw.Therefore, LD50 was considered to be >15000 mg/kg bw when 10 Wistar II female rat was treated withBenzenesulfonic acid,2-2’-(1,2-ethenediyl)bis(5-((4-(bis(2- hydroxyethyl)amino)-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-, free acid orally by gavage.
