Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
