Key value for chemical safety assessment

Skin sensitisation

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

No reliable study with single superphosphate is present. In a reliable skin sensitisation study, the LLNA test, performed according to OECD 429, EC B42 and EPA guidelines, diammonium hydrogenorthophosphate does not show sensitising properties.


Migrated from Short description of key information:
No reliable study with single superphosphate itself was present, however a reliable LLNA study showed no sensitisation of diammonium hydrogenorthophosphate.

Justification for classification or non-classification

Based on the available data, single superphosphate does not have to be classified according to Directive 67/548/EC and the CLP Regulation for skin sensitisation.
