Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
LD50 > 1000 mg/kg. It should be noted that this study could be waived as it is not relevant to the expected exposure to the substance. This is in accordance with Annex VII, Section 8.5.1 which states that
8.5.1. By oral route - The study need not be conducted if a study on acute toxicity by the inhalation route (8.5.2) is available.”
However, this study is included as supporting information to fulfil this data endpoint.
Although a limit test at > 1000 mg/kg no classification is proposed for oral toxicity, as this route of exposure is not anticipated.
Executive summary:

LD50 > 1000 mg/kg in a limit test. This study is included as supporting information to fulfil this data endpoint.

Although a limit test at > 1000 mg/kg no classification is proposed for oral toxicity, as this route of exposure is not anticipated.
