Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 > 4.0 (EPI Suite v4.11, KOCWIN v2.00, MCI method and log Pow based, 25 °C)

Key value for chemical safety assessment

Additional information

No experimental studies are available investigating the adsorption/desorption potential of Bis(1-methylheptyl) adipate (CAS 108-63-4). Therefore, the log Koc was estimated using KOCWIN v2.00 based on the Molecular Connectivity Index (MCI) and the log Kow method, respectively.

The obtained log Koc estimations were 4.52 based on MCI and 5.29 for the log Pow based estimate. Both models indicate a high potential for adorption to particles of soil and sediment, which is in line with the high estimated log Pow (> 8 at 20 °C).
