Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test substance was considered to be non-lethal under the conditions of the study and based on an LD50 of 5 g/kg bw.
Executive summary:

In an acute toxicity study the substance was administered to Sprague Dawley rats (5 animals/sex/dose) by oral gavage at a dose level of 5 g/kg bw (single administration). There were no mortalities or signs of clinical toxicity, mean body weight gain was comparable with the control animals and no abnormalities found at macroscopic post-mortem examination. The LD50 is 5 g/kg bw.
