Reference
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (sensitising)
- Additional information:
Skin sensitization:
As per the column 2 of Annex VII of REACH regulation, the available information indicates that the substance 2-aminobenzenesulphonic acid is a strong acid (pH < 2.0). Also the substance is classified as very corrosive. Thus testing for skin sensitization is not likely. Hence this endpoint was considered for waiver.
Migrated from Short description of key information:
The test substance 2-aminobenzenesulphonic acid is expected to be sensitising to skin.
Justification for selection of skin sensitisation endpoint:
As per the column 2 of Annex VII of REACH regulation, the available information indicates that the substance 2-aminobenzenesulphonic acid is a strong acid (pH < 2.0). Also the substance is classified as very corrosive. Thus testing for skin sensitization is not likely. Hence this endpoint was considered for waiver.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
The test substance 2-aminobenzenesulphonic acid is considered as sensitising for the purpose of classification.
