Any other information on results incl. tables
There were no deaths during the course of the study, hence no necropsies were performed. No symptoms of systemic toxicity were observed in the animals.
The second and third induction sites could not be evaluated due to the slight pigmentation of the skin still present from the first induction and the additional induction applications.
After challenge, animals were depilated 3 hours prior to the 24-hour reading to clean the skin area from the staining produced by the test item and to facilitate the reading of the skin reactions.
Applicant's summary and conclusion
- Interpretation of results:
- other: not classified according to the CLP Regulation (EC 1272/2008)
- Conclusions:
- Not skin sensitizer.
