Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 8.34 (MCI)

Key value for chemical safety assessment

Additional information

Experimental data on the adsorption potential of 2,2-bis[[(1-oxoheptyl)oxy]methyl]propane-1,3-diyl bisheptanoate (CAS 25811-35-2) are not available. Calculated values using KOCWIN Program (v2.00) indicate that the substance has the potential to adsorb to soil and suspended matter (Birkhofer, 2014). Based on the molecular conductivity index (MCI) a log Koc of 8.34 was calculated whereas based on the log Kow a log Koc of 6.7 was calculated. This model has no universally accepted definition of model domain, but the substance is outside of the domain of the training set (log Kow of the training set: -2.11 to 9.10; log Kow of the substance: 10.67). The definite values may not be fully reliable, but indicate a high adsorption potential, which can be taken into account for further assessments. Therefore, it can be assumed that the adsorption potential of the substance is high.
