Description of key information

log Koc (25 °C) = 8.4 

Key value for chemical safety assessment

Additional information

The adsorption/desorption potential of ethyl 3,5 -dichloro-4 -hexadecyloxycarbonyloxybenzoate (AF-366) on soil and sewage using HPLC was evaluated in a study by Erstling and Jungheim (2003). This test was conducted according to EU Method C.19, equivalent to OECD Guideline 121 (2001), under GLP conditions. The resulting log Koc value was determined to be 8.4 at 25 °C, which indicates that the substance has a high potential for adsorbing to solid particles.
