Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 2.51 - 2.77 (Molecular Connectivity Index); 3.06 - 3.34 (estimation based on log Kow) (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No studies investigating the adsorption/desorption behaviour of Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters are available. Using KOCWIN v2.00, log Koc values of 2.51 - 2.77 and 3.04 - 3.34 were calculated, based on log Kow and on molecular connectivity index (MCI), respectively. Based on this information, it can be assumed that Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters has a considerable potential for adsorption.
