Description of key information

According to the calculated Log Koc between 4.1 - 4.6 amides, C16-C18 (even numbered) has an adsorption/desorption potential to soil and sediment.

Key value for chemical safety assessment

Additional information

No experimental studies investigating the adsorption/desorption of amides, C16-C18 (even numbered) are available. Because the substance is a composition of different homologues, the adsorption/desorption potential was calculated for representative components using SRC KOCWIN v2.00.

The QSAR calculation indicate that the components of amides, C16-C18 (even numbered) are expected to adsorb to suspended solids and sediment based upon the log Koc between 4.1 - 4.6 as calculated for the uncharged molecule.
