Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
A LD50 was > 5000 mg/kg bw 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 > 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. Skin irritation findings included erythema (slight in 3 animals, moderate in 3 animals) and edema (slight in 4 animals, moderate in animals) on Day 7.
