Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LD50 of the test substance is > 1100 mg/kg bw
- Executive summary:
Rabbits (5/sex) were dermally exposed to the test substance for 24 hours. No effects other than slight erythema and well defined oedema (not observed after day 9) were reported. Body weight gain was considered normal. Necropsy did not reveal any findings. The LD50 is > 1100 mg/kg bw.
