Results and discussion
Any other information on results incl. tables
No signs of systemic toxicity were noticed in all animals during the study period. The expected mean body weight gain was generally observed in the course of the study.
When applied as 50% solution in DMF, the test substance did not induce a biologically relevant increase (no increase above the cut off Stimulation Index of 3) of 3H-thymidine incorporation into the cells from the auricular lymph nodes. However, a statistically significant increase for 3H-thymidine incorporation was noted. There were no statistically significant or biologically relevant increases in lymph node cell counts, lymph node weights or ear weights as well. The test-substance preparation did not cause any increase in ear weights, demonstrating the absence of relevant ear skin irritation.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
