Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The log Koc of Sorbic acid as determined according to OECD 121 was -1.82. However, it must be noted that this value only indicates the order of magnitude of it, as some deviations from the guidance were seen during the study leading to uncertainties regarding the exact determination of the value, followed by a limitation of the validity of the study. Since the Sorbate anion is the environmental relevant one, and as the presence of Sorbic acid or Sorbate anion is pH dependent, the results can be extrapolated to Potassium sorbate.
