Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The bioaccumulation potential of Dodecane-12-lactam was investigated experimentally in Cyprinus carpius (CITI 1992) and calculated with EPIWIN.

The experimentally derived bioconcentration factors at two concentration levels were 0.8 - 1.2 (0.5 mg/l) and <2.6 (0.05 mg/l) respectively. The calculated BCF was 35.35 (BCFWIN v2.14).

Conclusion on classification

The substance is not subject to labelling provisions as to environmental hazard by Directive 67/548/EWG and under regulation 1272/2008.
