Skin sensitisation

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

All test were conducted scientifically acceptable but the score values were not mentioned in the publication of the test results.

All tests with thymol were negative in the open epicutaneous test (OET), the Draize test (DT), the Maximisation test (MT) and the test with Freund's complete adjuvant (FCAT).

From a weight of evidence consideration thymol is not sensitizing.

Also from several patch test in humans conducted in dermatological institutions the sensitizing potential of thymol is very low

Migrated from Short description of key information:
