Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The LD50 for the acute dermal exposure of rats to the test item was determined to be > 2000 mg/kg b.w., the only concentration tested.
Executive summary:

The acute dermal toxicity of the test item was determined in a guideline limit test with male and female wistar rats at a dose level of 2000 mg/kg b.w. The LD50 was determined to be > 2000 mg/kg b.w., the only concentration tested. No deaths or effects on organs were observed. At the site of treatment, spots with crusts were noted in 2 females on day 8 and 1 female on day 15. The test item does not meet the GHS criteria and is not classified.

The study is a GLP compliant, guideline study suitable for use for assessment of this endpoint, with restrictions.
