Applicant's summary and conclusion

Interpretation of results:

not sensitising

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The substance biphenyl-2-ylamine is estimated to be non-sensitizing to skin of human and Guinea pig

Executive summary:

The skin sensitisation effect of biphenyl-2-ylamine was estimated using QSAR Toolboox version 3.3

The test substance biphenyl-2-ylamine was estimated to be non-sensitising to skin of human and Guinea pig. Considering the CLP criteria for classification of substances, it is concluded that biphenyl-2-ylamine is likely to be classified as not sensitizing to the human and Guinea pig skin.
