Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this limit test the acute dermal median lethal dose (LD50) of the test item was found to be higher than 2000 mg/kg body weight in male and female RjHan:(WI) Wistar rats.
- Executive summary:
An acute dermal toxicity study was performed with the test material in RjHan:(WI) Wistar rats, in compliance with OECD Guideline No.: 402. A limit test was carried out at 2000 mg/kg body weight (bw) in both sexes (5 rats/sex). The test item was applied as supplied as a single dermal 24-hour exposure followed by a 14-day observation period. Clinical observations 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 euthanized and a gross macroscopic examination performed at the end of the 2-week observation period (Day 14). The results of the study were summarized as follows: No mortality occurred. No clinical signs were observed after the treatment with the test item or during the 14-day observation period and no local dermal signs were existing. The body weight and body weight gain of treated animals did not show any adverse effects. There was no evidence of the test item-related observations at a dose level of 2000 mg/kg bw at necropsy. Taken from this observations a LD50 is > 2000 mg/kg body weight.
