Materials and methods

Principles of method if other than guideline:
The EPI Suite™ method that estimates Kow is KOWWIN and it uses a "fragment constant" method to predict Kow. In the "fragment constant" method, a molecule is divided into fragments (atoms or larger functional groups) and the assigned coefficient values for each fragment are added to give the Kow estimate.
