Any other information on results incl. tables

No mortalities occurred. No compound-related findings were observed with regard to local and clinical observation, determination of body weight and necropsy examination.

Applicant's summary and conclusion

Executive summary:

The single dermal administration of the test substance (ZK 10882) to male and female rats at the limit dose of 2000 mg/kg was tolerated without any mortality. No compound-related findings were observed with regard to local and clinical observation, determination of body weight and necropsy examination.

The acute dermal toxicity of 6 -Chlor-Chlormethyldien in rats is therefore above 2000 mg/kg body weight.

No local intolerance reactions at the application sites were observed.
