Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
From the water surface, the hydrolysis product neodecanoic acid will not evaporate into the atmosphere.
Key value for chemical safety assessment
Additional information
A Henry law constant (HLC) of 650 Pa*m³/mol was calculated by SRC HENRYWIN v3.20 with the bond estimation method (BASF SE, 2009). This indicates a volatile character of the test substance. However, neodecanoyl chloride degrades spontaneously in contact with water to form neodecanoic acid. Therefore, this model calculation may be of low relevance.
Neodecanoic acid has a HLC of 0.535 Pa*m³/mol, which was calculated SRC HENRYWIN v3.20 with the bond estimation method (BASF SE, 2009). Additionally, most of the neodecanoic acid molecules will be present in dissociated form under environmental relevant pH conditions (pKa = 4.69).
Therefore it may be concluded, that due to rapid hydrolysis, neodecanoyl chloride will only exist for a short time in water and the hydrolysis product does not evaporate into air.
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.
