Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: exact LD50 not determinable due to absence of adverse toxic effect, no indication of skin irritation up to the relevant limit dose level.
- Mortality:
- No deaths ocurred during the study.
- Clinical signs:
- Yellow staining and test article remnants on the application site were observed. Yellow staining persisted in two males and three females until day 13.
- Body weight:
- Body weights were within the range commonly recorded for animals of this strain and age.
- Gross pathology:
- No macroscopic findings were observed at necroscopy.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Single dermal application of the limit dose of 2000 mg test substance per kg bw did not cause lethality in 5 male and 5 female HanIbm: WIST rats during the 14 day observation period, resulting in a LD50 > 2000 mg/kg bw.
- Executive summary:
5 Male and 5 female rats (HanIbm: WIST) were subjected to test acute dermal toxicity according to the acute dermal toxicity test method (OECD TG 402, limit test). The test substance was applied semiocclusively to the animals backs at the limit dose of 2000 mg/kg bw in propylene glycol. After 24 h the test substnce was removed, the skin was washed clean and the animals were observed for 14 days. No animal died within the observation period, resulting in a LD50 > 2000mg/kg bw. No skin irritation was observed either.
