Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 > 5 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No studies investigating the adsorption/desorption behaviour of Hexanedioic acid, di-C16-18 alkyl esters (CAS 92969-90-9) are available. Using KOCWIN Program (v2.00), log Koc values in the range of 9.69 to 10.73 were calculated for its main components based on the molecular conductivity index (MCI) and based on log Pow models. These models have no universally accepted definition of its model domain, but since the substance is outside the Kow range of the training set, the results should be taken with caution. The definite values for the main components may not be fully reliable, but indicate a high adsorption potential of the UVCB substance, which is also to be expected based on the high calculated log Kow values of the main components (10.56 - 11.80, KOWWIN v1.68).

Based on the available information, it can be assumed that the adsorption potential of Hexanedioic acid, di-C16-18 alkyl esters (CAS 92969-90-9) is high.
