Applicant's summary and conclusion

Interpretation of results:
other: sensitising
Conclusions:
The test material Sulfanilic acid (CAS No: 121­57­3) was observed to be sensitizing on guinea pigs.
Executive summary:

The skin sensitization test was conducted on guinea pigs by guinea pig maximization test for test chemicalSulfanilic acid (CAS No: 121­57­3).Since skin sensitizing effects were observed for the test chemical. ThereforeSulfanilic acid (CAS No: 121­57­3)was considered to be sensitizing to guinea pigs.
