PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Not P/vP: Screening studies showed no relevant biodegradation. The main behaviour in the aquatic environment is hydrolysis which occurs very rapid with a half-life of 2 hours. The PBT assessment of potential hydrolysis products (oligomeric and polymeric ureas) has to be performed separately from the parent substance. These products are preliminary considered to be P(vP) but not B(vB). Therefore, also the hydrolysis products are not PBT.
Not B/vB due to a rapid hydrolysis with a half-life of 2 hours. Performance of a BCF study is technically not possible. Hydrolysis products (oligomeric and polymeric ureas) are not B or vB.
Not T due to the proven absence of relevant toxic effects.
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).
