Applicant's summary and conclusion

Interpretation of results:
harmful
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The sample SAT 060267 is harmful if swallowed for actue toxicity by the oral route.
Based on these results:
- according to the GHS classification, SAT 060267 should be classified as : harmfull if swallowed (category 4) for acute toxicity by the oral route
- according to EC criteria for classification and labelling for dangerous substances and preparations, SAT 060267 should be labelled as: harmfull if swallowed (R22)
Executive summary:

This study report demonstrated that the sample SAT 060267 is harmful if swallowed for actue toxicity by the oral route. The oral LD50 value of SAT 060267 (active ingredient) in Wistar rats was established to be within the range of 300-2000 mg/kg body weight.
