PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The partition coefficient (log Kow) of 1,3 -diethyl-2 -thiourea was assessed according to a method similar to the shake-flask method. The value obtained (log Kow = 0.57) is < 4.5, which means that the substance should not be considered as bioaccumulable. It is thus not considered as a PBT or vPvB substance.
In addition, a screening PBT assessment was conducted with each of the degradation products, identified by the EAWAG tool, with the US EPA EPISUITE software. None of the identified degradation products are persistent nor bioaccumulable according to Biowin estimations.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
