Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to Column 2 of Annex IX of REACH, a study on adsorption / desorption of acetate does not need to be conducted since acetate has a low log Kow (i.e. log Kow ≤ 3). According to an experimental database match (Hansch, C. et al. 1995) of the QSAR model software EpiSuite v.4.1, acetic acid has a log Kow of -0.17. Soil adsorption coefficients estimated with KOCWIN v2.00 range from 1 L/kg (MCI method) to 1.153 L/kg (Kow method) further point to a low potential for adsorption in the environment. Further, acetate and its degradation products decompose rapidly in the environment.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
