PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

The substance consists of several constituents.

Based on the available data on biotic and abiotic degradation, bioaccumulation and toxicity neither of the constituents fulfills the criteria for P, B and T(not PBT) or vP and vB (not vPvB).

The UVCB substance fulfils the screening criterion for persistence. However, as the criteriafor toxicity and bioaccumulation are not fulfilled it is not a PBT or vPvB substance. No emission characterisation is performed.

The substance evaluation process for PBT properties is ongoing and a tiered testing strategy is required. The first tests on PC properties (water solubility and logKow) for one isomer of the constituent ditertbutyldiphenylamine are completed.

Likely routes of exposure:

Regarding all available data on biotic and abiotic degradation, bioaccumulation and toxicity it can be stated that the substance does not fulfill the PBT criteria (not PBT) and not the vPvB criteria (not vPvB).
