Any other information on results incl. tables
After the 1st challenge, 95% of the test group animals and 70% of the control animals revealed skin changes on the application area of the test substance.
After the 2nd challenge, the 25% and the 12% test solution provokes skin changes on 70% and 15% on the test group animals, respectively. The animals of the control group showed no reactions.
Applicant's summary and conclusion

- Migrated information
- Executive summary:
The test substance m-chloroaniline was evaluated for potential skin sensitizing properties in a maximisation test as decribed by Magnusson and Kligman. The test was performed on female guinea pigs. The following test compound concentrations were used in this test:
Intradermal induction: 5%, Topical induction: 50%, 1st Challenge: 50 %, 2nd Challenge: 25% and 12%.
Under the condition of the maximisation assay, m-chloroaniline is positive. Based on these data a classification as R43 (GHS: Skin Sens. 1B; H317) is justified.
