Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category IV
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The oral LD50 was found to be 0.85 g/kg in males and 0.53 g/kg in females. Therefore it is classified as Category 4, signal word warning, hazard statement H302: Harmful if swallowed.
- Executive summary:
The test substance Busan 11-M1 was administered to 8 rats/sex/dose male and female Sprague-Dawley rats in dosages administered at 0.34, 0.50, 0.73, 1.07, 2.31, 5.0 g/kg. The test animals were observed for 14 days following administration. Under the conditions of this study, the oral LD50 of the test substance was determined to be 0.85 g/kg in males and 0.53 g/kg in females . Based on this result, Busan 11-M1 is classified as Category 4, signal word warning, hazard statement H302: Harmful if swallowed in accordance with Regulation EC No. 1272/2008.
