Description of key information

The log Koc for TAEE ranges from 2.16 to 3.73; the average log Koc value of 2.95 (Koc of 891 l/kg) will be used in the assessment.

Additional information

One GLP-compliant OECD 211 guideline test is available. The distribution coefficient in soil (expressed as log Koc) of TAEE was estimated at 25 °C to be between 2.16 and 3.73, all within a 95% confidence range of 1.74 to 4.12 (Covance Laboratories Ltd, 2009a). The log Koc was also calculated with the program KOCWIN™ v2.00 (2008) (see QMRF and QPRF as attached to the respective IUCLID entry) using an average log Kow of 3.15, which resulted in a log Koc of 2.58. The experimental log value of 2.95 (Koc of 891 l/kg) will be used in the assessment.
