Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
Parent compound: In contact with water, the substance will hydrolyse rapidly.
Hydrolyisis product neodecanoic acid: According to structural properties, hydrolysis is not probable.
After evaporation or exposure to air, the substance and its hydrolysis product will be slowly degraded by photochemical processes.
No data are available on phototransformation in water or in soil.
Biodegradation
Hydrolysis product: Neodecanoic acid: poorly biodegradable (OECD 301 F, Exxon Mobile, 1996).
Regarding the hydrolysis products HCl and CO2, biodegradation is not applicable due to the inorganic character of these molecules.
Regarding the biodegradation in soil or sediment there are no data available.
Bioaccumulation
Parent compound: neodecanoyl chloride: Accumulation in organisms is unlikely.
Hydrolysis product: neodecanoic acid: Significant accumulation in organisms is not expected.
Neodecanoyl chloride has an estimated log Kow of 3.35 (BASF SE, 2009). The corresponding BCF estimate is 74.9 (BASF SE, 2009), therefore significant accumulation in organisms is unlikely. However the test substance rapidly hydrolyses and forms neodecanoic acid. Hence, the BCF-estimate may be of low relevance.
The hydrolysis product neodecanoic acid has an estimated log Kow of 3.9 (BASF SE, 2009). Therefore, based on log Kow moderate accumulation in organisms is possible. However, the BCF was estimated to be 3.16 (BASF SE, 2009) and ca. 7 (BASF SE, 2010) using BCFBAF v3.00 and Catabol - BCF base-line model (v01.04), respectively. Based on these BCF-estimates, significant accumulation in organisms is not expected.
Transport and distribution
The estimated low Koc values of the parent compound and the hydrolysis product indicate that adsorption to soils or sediments is not expected (BASF, 2009; BASF 2010).
The hydrolysis product neodecanoic acid will not evaporate into the atmosphere from the water surface (BASF, 2009).
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.
