Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
According to European Union legislation substance of low toxicity (LD50 >2000 mg/kg b.w.) is not classified to the class of toxicity based on the strength of toxicity in acute exposure conditions.
Executive summary:

The test results showed no toxicity on rats with a LD50 > 5000 mg/kg bw.
