Administrative data

PBT assessment: overall result

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

The data used for the assessment are derived from the category components, but-1-ene (CAS 106 -98 -9), 2-butene (CAS 107 -01 -7) and 2 -methylpropene (CAS 115 -11 -7). The presented values were based on the most conservative data to allow for a more protective approach in this assessment.

Conclusion (i): The substance does not fulfil the PBT and vPvB criteria.

Therefore the PBT/vPvB assessment stops at this point.

Likely routes of exposure:

This section of the report is not required for non PBT/vPvB substances.
