Materials and methods

Test guideline
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 401 (Acute Oral Toxicity)
Principles of method if other than guideline:
The study was conducted according to an internal protocol which in principle is comparable to the OECD Guideline 401. A test group consisting of 5 animals/sex was treated by single gavage application with an aqueous solution of the test substance. The animals were observed for mortality and for clinical symptoms of toxicity. At the end of the observation period of 14 days, the surviving animals were sacrificed for the purpose of necropsy; animals that died during the observations period also were subjected to necropsy.
GLP compliance:
no
Test type:
standard acute method
Limit test:
yes

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test substance was not acute toxic and thus, a LD50 greater than 10,000 mg/kg bw was established.
