Applicant's summary and conclusion
- Interpretation of results:
- other: not sensitising
- Conclusions:
- The test material Brilliant Black 1 (CAS No: 2519-30-4) was considered to be non-sensitizing to the guinea pigs skin.
- Executive summary:
The skin sensitization test of test chemical Brilliant Black 1 (CAS No: 2519-30-4) was carried out in guinea pigs to determine its sensitization efficacy.
Since the guinea pigs did not elicit any sensitizing effect, the test chemical Brilliant Black 1 (CAS No: 2519-30-4) was considered to be not sensitizing to the guinea pigs.
