PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

Because 1,2,3,6-tetrahydrophthalic anhydride (THPA D4) hydrolyses almost instantaneously on contact with water, to give cyclohex-4-ene-1,2-dicarboxylic acid (THPAc, D4 CAS 88 -98 -2), the PBT assessment was made on that substance. As result, cyclohex-4-ene-1,2-dicarboxylic acid does not meet the criteria to be regarded as either PBT or vPvB.
