20 °C

Additional information

Two studies are available from the migrated NONS file provided by ECHA. One shows a log Pow value of 3.27, and the other shows a value of 4.15 at 20 degrees centigrade. The 4.15 value has been taken as a worst case scenario.

It is concluded that the log Pow value of N-(n-octyl)-2-pyrrolidinone is 4.15, as this is the worst case demonstrated.
