PBT status:

the substance is not PBT / vPvB

Justification:

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

Likely routes of exposure:

Because the substance does not fulfil the PBT and vPvB criteria, no emission characterisation is performed.
