Description of key information

The estimated LogKoc values for thymol, using different accepted calculation methods are 2.90, 2.98 and 3.34 (Currenta, 2010).

Key value for chemical safety assessment

Additional information

According to the classification scheme of Swann et al. (1983) the estimated log Koc-values 2.90 -3.3 indicates a moderate to high sorption potential to soil and sediment and suggests a slow migration potential to ground water. As a worst-case assumption, the lowest log Koc of 2.90 is used for further exposure assessment of PNEC in sediment and soil using EPM method.
