Any other information on results incl. tables
There was no mortality or remarkable differences in body
weight or absolute/relative liver or kidney weights.
Abnormal skin responses (desquamation, and fissures) were
noted on the test substance-treated rabbits. No abnormal
skin responses were noted on the control animals.
Applicant's summary and conclusion
- Conclusions:
- The no-observed-effect-level (NOEL) for systemic effects was
determined to be greater than 1.0 mL/kg/application of the
test substance to rabbits under the conditions employed in
this study.
