Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Log Koc: 2.45-4.32

Key value for chemical safety assessment

Additional information

No experimental data are available investigating the adsorption/desorption potential of N-(1-oxotetradecyl)sarcosine (CAS 52558-73-3). Therefore, the log Koc was estimated using the method according to Franco and Trapp (2008). The resulting log Koc values range from 2.45 to 4.32, indicating a considerable potential for adsorption of the substance to soil and sediment particles.
