PBT assessment: overall result

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

The test item has a salt like character consiting of ethanolamine and etidronic acid. From a formal point of view the registered substance is readily biodegradable fulfilling the criteria for ready biodegradation. However, a closer look on the mass balance indicates that a stable metabolite may be  formed.  Whereas the ethanolamine is expected to degrade fast after dissociation in water, the etidronic acid part may be stable. A REACH dossier is confirming that the substance is not readily biodegradable, not bioaccumulative based on log KOW (-3.5), and has a chronic toxicity of > 0.01 mg/l and a acute toxicity of >1 mg/l

Although etidronic acid is not readily biodegradable, the substance is not classified and labelled with regard to ecotoxicological properties.

Similarly also for ethanolamine (CAS: 141 -43 -5) a REACH dossier is available confirming that the substance is readily biodegradable, not bioaccumulative based on log KOW (1.32), and has a chronic toxicity of > 0.01 mg/l.
