Description of key information

The log Kow value of   bis[2(2 butoxyethoxy)ethyl]butanedioate  is 2.25. This value is calculated with the KOWWIN model. 

Key value for chemical safety assessment

Additional information

The octanol-water partition coefficient was calculated by the QSAR modelling tool EPI suite, v 4.10 edited by EPA. The model which was used is the KOWWIN v 1.68. The estimation is based on the structure of the compound. The structure is divided into fragments (atom or larger functional groups) and coefficient values of each fragment or group are summed together to yield the log Kow estimate.

The log Kow value of bis[2(2 butoxyethoxy)ethyl] butanedioate is 2.25
