PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

The PBT Assessment for the test substance is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2012).


The test substance was not readily or inherently biodegradable in standard studies according to OECD 301 F (0% after 28 days) and OECD 302 B (0% after 28 days). Thus, the test substance meets the screening criterion for persistence and is considered to be vP.


Based on the log Kow value of < 0.3, the test substance is expected to have low bioaccumulation potential.


The NOEC for algae is 3.8 mg/L and thus clearly above the trigger value of 0.01 mg/L. Further long-term data are not available. Furthermore, the test substance is not classified according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 for environmental or human health hazards. Thus the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 are not met and the test substance does not fulfil the T criterion.
