> 5 000 mg/kg bw
Based on:
test mat.

Applicant's summary and conclusion

Interpretation of results:
other: CLP criteria not met
Conclusions:
LD50 > 5000 mg/kg bw
Executive summary:

The substance was tested according to a method similar to the OECD guideline 401. 5 males and 5 females were administered at a dose of 5000 mg/kg bw and observed for 14 days.

No relevant clinical signs were observed in none of the animal tested. The LD50 was then greater than 5000 mg/kg bw.
