Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The fate and behaviour of Potassium sorbate in the environment was investigated in various tests and by using modelling data. The test were conducts with Potassium sorbate as well as with Sorbic acid as a surrogate. Since the Sorbate anion is the environmental relevant one, and as the presence of Sorbic acid or Sorbate anion is pH dependent, all results summarized below can be extrapolated to Potassium sorbate.
The main compatement for the environmental fate of Potassium sorbate is the water phase. Modelling data indicate that almost 100% of the substance reaches the water phase. Potassium sorbate is not abiotically but very good biotically degradable. Its half-life in air is comparatively low, however, due to its low volatiliy, photolysis is a degradation pathway of minor importance as only a minimal fraction will reach the air. Its potential for adsorption is very low, thus it possessed a high potential for leaching into the groundwater body if applied to soil. Potassium sorbate has no potential to accumulate in the food chain, neither aquatic, nor terrestric.
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.
