Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test material was demonstrated to have an acute oral oral LD50 greater than 40.0 mL/kg in the rat.
Executive summary:

METHOD

A preparation declared to contain 90 % of test item was administered in a single dose by gavage to five groups of Sherman-Wistar rats consisting of one male and one female. Mortality after a fourteen day observation period was reported.

RESULTS

No mortality was observed in rats dosed with 2.5, 5.0, 10.0, 20.0 or 40.0 mL/kg of the test material.

CONCLUSION

The test material was demonstrated to have an acute oral LD50 greater than 40.0 mL/kg in the rat.
