No mortality or signs of toxicity in females at 300 and 2000 mg/kg bw

Effect levels

Sex:

female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Based on:

test mat.

no abnormalities

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The LD50 of the testsubstance is > 2000 mg/kg bw

Executive summary:

Female rats (n=1) received a single dose of the test substance at 300 and 2000 mg/kg bw in a sighting study. In absence of mortality or signs of toxicity, additional 4 females were dosed at 2000 mg/kg bw. No mortality was observed in these females and no effects on body weight, clinical signs or gross examination were noted. The study followed the fixed dose procedure without any deviarions from the guideline. The LD50 is > 2000 mg/kg bw.
