Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

The test article was evaluated at a concentration of 25% in DMSO, with DMSO as the vehicle control and 25% HCA as the positive control.


All animals survived the in-life phase of the study and were observed to be normal. Ear thickness measurements and clinical observations indicated that treatment with the test article did not result in dermal irritation.

Migrated from Short description of key information:

In a LLNA study in mice, topical application of the test article at 25% in DMSO resulted in an SI value of 1.6. Therefore, the test article was considered not to be a skin sensitizer.
