Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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).
