Description of key information
The log Pow value for N-(n-octyl)-2-pyrrolidinone is 4.15 at 20 degrees centigrade
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.15

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.
