Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The LD0 and LD50 of Reactive Rat FC 73270 in male and female rats is > 2000 mg/kg body weight.
Executive summary:

In an acute oral toxicity study, groups of 6-10 weeks old Hsd:Sprague Dawley rats, 5/sex were given a single oral dose of Reactive Red FC 73270 in deionized water at a dose of 2000 mg/kg body weight and observed for 14 days.

Oral LD0 and LD50:

Male >2000 mg/kg body weight

Female >2000 mg/kg body weight

Combined >2000 mg/kg body weight

 

Reactive Red FC 73270 is of low toxicity based on the LD0 > 2000 mg/kg/d in both male and female Hsd:Sprague Dawley rats.
