no study available

Additional information

The in-vivo tests on the rabbit skin and eye are the standard tests for skin and eye irritation.

As the test data was available, no in-vitro tests were performed.


Justification for selection of skin irritation / corrosion endpoint:
Only one study available

Justification for selection of eye irritation endpoint:
Only one study available

Effects on eye irritation: slightly irritating

Justification for classification or non-classification

The available data is conclusive but not sufficient for classification
