Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The median lethal dose after a single dermal administration (acute dermal LD50) was greater than 2000 mg/kg bw in male and female RccHan:WIST rats.
- Executive summary:
Five male and five female RccHan:(WIST) rats were treated with a single, semi occlusive dermal application of the test substance at a dose of 2000 mg/kg bw. The test item was applied as supplied. The application period was 24 hours, followed by a 14-day observation period. Clinical observations along with a check of viability and mortality were performed on all animals at 1 and 5 hours after dosing and daily for 14 days thereafter. Body weight was measured prior to dosing on Day 0 and on Days 7 and 14. Rats were killed and given a gross macroscopic examination at the end of the 2-week observation period (Day 14).
There were no mortalities. No adverse clinical signs were observed after treatment with the test item. There were no treatment related effects on body weight or body weight gain during the observation period. There were no treatment-related effects at necropsy.
The median lethal dose after a single dermal administration (acute dermal LD50) was greater than 2000 mg/kg bw in male and female RccHan:WIST rats.
