Description of key information

Adsorption/desorption screening: log Koc = ca. 4.124 based on log Kow (KOCWIN) and Koc = 13290 L/kg

Key value for chemical safety assessment

Koc at 20 °C:
13 290

Additional information

To fulfil the endpoint adsorption/desorption screening, the Koc of Ethylhexyl Methoxycinnamate was predicted with a QSAR. For this QSAR calculation the accepted software KOCWIN (version 2.00, part of the most recent Estimation Programs Interface, EPI Suite) was used. This resulted in a predicted Koc value (based on log Kow) of ca. 13290 L/kg (log Koc ca. 4.124).
