Additional information

A single study has been submitted. The study follows US EPA guidelines, Subdivision N, Secion 163 -1, and the study has been performed to GLP standards - as such, the study is deemed to be reliable, and the results are accepted as being valid for the Koc determination of N-(n-octyl)-2 pyrrolidinone.

The Koc value of N-(n-octyl)-2-pyrrolidinone is therefore determined to be 270.
