Description of key information

Key value for chemical safety assessment

Skin sensitisation

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

The key infromation is read across from DTPMP acid (CAS 15827 -60 -8).


Migrated from Short description of key information:
In a guinea pig maximisation study conducted before OECD TG 406 and GLP (reliability score 2) DTPMP was not sensitising to the skin of guinea-pigs (Unilever 1979).

Justification for classification or non-classification

The available data suggest that there is no need to classify sodium salts of DTPMP for sensitising potential.
