Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

Based on the structural similarities and the read-across as described in the attached document, it can be concluded that Zinc bis(di C8-C10, branched, C9 rich, alkylnaphthalene sulphonate) (ZnDNNSA) is not a skin sensitizer.


Migrated from Short description of key information:
The structural analogue BaDNNSA was sensitizng in a Bühler test, but no sensitization was observed after application to the human skin (Bailey, 1985)

Justification for selection of skin sensitisation endpoint:
Based on human test data, it can be concluded that the structural analogue BaDNNSA does not have sensitizing properties

Justification for classification or non-classification

Based on the presence of human data on a structural analogue, the substance does not need to be classified.
