Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
According to OECD guideline 402 the acute dermal LD50 was determined to be > 2000 mg/kg. Thus, the test substance can be considered as not acutely toxic via the dermal route.
Executive summary:

According to OECD Guideline 402 the test material was applied at a dose of 2000 mg/kg to five male and five female rabbits. The substance was left in contact with the skin for 24 hours. None of the rabbits died during the study, slight to moderate erythema was observed in every animal at 24 hours after initiation of exposure. No test article related lesions observed in gross pathology. The acute dermal LD50 was determined to be greater than 2000 mg/kg.
