PBT assessment: overall result

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

Dodecane-12-lactam, manufacturing of, by-products from, distillation residues is present as a complex reaction product of unknown and variable composition. For this reason, a range of partition coefficient values was determined during a study performed according to the OECD 117 guideline. The mean partition coefficient range of duplicate determinations of Dodecane-12-lactam, manufacturing of, by-products from, distillation residues, was determined at pH 5, 7 and 9. For each pH, the major peak gives Log10 Pow < 4.5.

Thus, Dodecane-12-lactam, manufacturing of, by-products from, distillation residues should not be considered as bioaccumulable: it is not a PBT, nor vPvB substance.
