Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Considering the reported data of this toxicity test it can be stated that the test item Beta 30 showed no orally toxic characteristics, the LD50 was >2000 mg/kg bw.
- Executive summary:
The acute toxic class method according to OECD 423 was performed with the test item Beta 30. In the first and second step, the test item was given at a dose of 300 mg/kg bw to a group of 3 female rats (HsdRccHan : WIST) via gavage. No compound related mortality was recorded for any of the treated animals in step 1 and 2. Based on these results and in accordance with the acute toxic class regime, the third and fourth steps of the test were performed with 2000 mg/kg bw with further groups of 3 female rats. No compound related mortality was observed in step 3 and 4. A clinical examination did not reveal any signs of toxicity in any animal and test step. Further, no treatment related gross pathological changes were found in any animal and test step. Throughout the 14-days observation period, no weight loss was recorded for any animal. The weight gain was within the expected range.
The test item Beta 30 was concluded to show no oral toxicity, the LD50 was >2000 mg/kg bw.
