- Key result
- Sex:
- not specified
- Dose descriptor:
- LD50
- Effect level:
- > 5 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- There were no deaths.
- Clinical signs:
- other: Diarrhea was observed in 1 animal.
- Other findings:
- Skin irritation: Slight redness in 6 animals, moderate redness in 4 animals; slight edema in 3 animals, moderate edema in 7 animals.
Applicant's summary and conclusion
- Interpretation of results:
- other: Not acute harmful
- Remarks:
- in accordance with EU CLP (1272/2008 and its updates)
- Conclusions:
- A LD50 > 5000 mg/kg bw was established in an acute dermal toxicity study with rabbits.
- Executive summary:
In an acute dermal toxicity study with rabbits, similar to OECD TG 402 but non-GLP, the LD50 was greater than 5000 mg/kg bw. A group of 10 animals (strain, sex and age unspecified) received a single application of 5000 mg/kg bw test substance. There were no deaths. Diarrhea was observed in one animal. Skin irritation findings included erythema (slight in 6 animals, moderate in 4 animals) and edema (slight in 3 animals, moderate in 7 animals).
