Results and discussion
- Preliminary study:
- NA
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- No mortality occurred during the study period.
- Clinical signs:
- other: No clinical signs of ill health or behavioural changes were observed during the study period. Abnormalites in the treated skin area included scabs in one male between days 5 and 9.
- Other findings:
- Macroscopic post mortem examination of the animals at termination revealed a yellowish hard nodule in the papillary process of the liver in one female and pelvic dilation of the kidney in one male. These findings are incidentally noted among the animals of this age and strain and are considered not related to treatment with the test substance.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The dermal LD50 value of the test item in rats was established as exceeding 2000 mg/kg body weight.
- Executive summary:
In an acute dermal toxicity study, groups of young adult (8 weeks old) Wistar rats (5/sex) were dermally exposed to the test item for 24 hours to (25 cm2 surface) at a limit doses 2000 mg/kg bw. Animals then were observed for 14 days.
No mortality occurred during the study period. No clinical signs of ill health or behavioural changes were observed during the study period. Abnormalites in the treated skin area included scabs in one male between days 5 and 9. The body weight gain shown by the animals over the study period was considered to be similar to that expected of normal untreated animals of the same age and strain. However, three females showed low body weight gain over the second week of the study. Macroscopic post mortem examination of the animals at termination revealed a yellowish hard nodule in the papillary process of the liver in one female and pelvic dilation of the kidney in one male. These findings are incidentally noted among the animals of this age and strain and are considered not related to treatment with the test substance. The dermal LD50 value of the test item in rats was established as exceeding 2000 mg/kg body weight.
