Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance is an organic solid, white odourless powder, which melts at 134°C and decomposes prior to boiling at an atmospheric pressure of 1013 hPa. Its relative density is 1.20 at 20°C (compared to water). It has a vapor pressure of 1.8 x 10 -4hPa
at 20°C.The particle sizes L10 and L90 of the test item deduced from the particle size distribution is 16.57 µm and 254.18 µm, respectively.
Sorbic acid is soluble in water with a water solubility of 1.34 g/L and a log Po/w of 1.32 (at pH 2.5) and -1.72 (at pH 6.5).No self ignition temperature was observed until the maximum test temperature of 400 °C. Sorbic acid could not be ignited by a flame and no explosive or oxidising proporties are expected due to its chemical structure. The pKa of sorbic acid in aqueous solution of 20 °C was determined to be 4.65 +/- 0.04.
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.
