PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for Amides, C16 and C18-C20 (even numbered, unsaturated), N,N’-ethylenebis is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).
Persistence
One study according to OECD 301B resulted in < 16% (CO2 evolution) degradation after 28 d. Thus, according to the screening criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017) the substance is considered to be persistent (P) or very persistent (vP).
Bioaccumulation
One study according to “Circular on the Japanese Test Methods of New Chemical Substances, bioaccumulation test” resulted in a BCF of < 6.2. Thus, according to the definite criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 the substance is not considered to be bioaccumulative (B) or very bioaccumulative (vB).
Toxicity
Long-term toxicity testing with Daphnia magna resulted in a NOEC of ≥ 0.00564 mg/L (OECD 211). No toxicity in the range of water solubility. Moreover, the test substance is not classified according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 (2nd ATP). Thus, the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 are not met and the test substance is not considered to meet the T criterion.
Conclusion
In conclusion the substance is not considered to meet the criteria to be classified as PBT or vPvB based on the available data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
