Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test substance biphenyl-2-ylamine was estimated to be non-irritating to the eyes of rabbits
Executive summary:

The eye irritation effect of biphenyl-2-ylamine in rabbits was estimated using QSAR Toolbox version 3.3

The test substance biphenyl-2-ylamine was estimated to be non-irritating to the eyes of rabbits. Considering the CLP criteria for classification of substances, it is concluded that biphenyl-2-ylamine is not likely to be classified as an eye irritant.
