Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The oral LD50 of Caprinoguanamine in rats was > 10000 mg/kg bw.
Executive summary:

In an acute oral toxicity study similar to OECD guideline 401, 5 male and 5 female, fasted, young Wistar strain rats were given a single oral dose of Caprinoguanamine in DMSO at a limit dose of 10000 mg/kg bw and observed for 14 days. 5 male and 5 female rats were treated with an equal amount of DMSO (8 mL/kg bw).

Within a few hours after treatment the rats showed sluggishness and several rats lost consciousness for a few hours. One male and one female showed encrustations round eyes and nostrils. They died on the second and third day after test substance treatment, respectively. The survivors recovered within 24 hours and looked quite healthy at the end of the observation period. None of the rats treated with DMSO showed any reaction upon treatment. No abnormalities were observed at necropsy.

Oral LD50 (rat, females/males) > 10000  mg/kg bw
