Migrated from Short description of key information:
Benzidine-2,2’-disulphonic acid was estimated to be sensitizing to skin of human in accordance to the Danish EPA database that is considered to be an authoritative database
Justification for selection of skin sensitisation endpoint:
Danish EPA is considered to be an authoritative database
Justification for classification or non-classification
Benzidine-2,2’-disulphonic acid was estimated to be sensitizing to skin of human in accordance to the Danish EPA and hence classified as a skin sensitizer
