PBT assessment: overall result

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

Because hexahydrophthalic anhydride (HHPA) hydrolyses almost instantaneously on contact with water, to give hexahydrophthalic acid (HHPAc, CAS 1687-30-5), the PBT assessment was made on that substance.

As result, hexahydrophthalic acid does not meet the criteria to be regarded as either PBT or vPvB.

Likely routes of exposure:

It is predicted the soil to be the most likely target compartment
