Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 estimated neo-decanoic acid Koc is 121. The Koc of neo-decanoic acid may be sensitive to pH. Neo-decanoic acid vapor pressure is very low, 0.65 Pa, which suggests limited volatilization from the terrestrial compartment. In comparison, Henry’s Law constant for neo-decanoic acid is calculated as 0.54 Pa-m3/mole at 25 degrees C, which indicates that volatilization from water is not expected to occur at a rapid rate, but may occur. Neodecanoic acid is a weak organic acid with an estimated dissociation constant (pKa) of 4.7. Consequently, neodecanoic acid, at neutral pH, which is typical of most natural surface waters, is expected to dissociate to the ionised form and therefore, remain largely in water. |
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.
