Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to rapid hydrolysis, 3,5,5-trimethylhexanoyl chloride will not be present in the environment for a significant time. Therefore, the fate in the environment is mainly based on the hydrolysis product 3,5,5-trimethylhexanoic acid.
Adsorption/desorption
Regarding the charged molecule at pH 7, the log Koc of 3,5,5-trimethylhexanoic acid was estimated to be 1.99 (Koc = 97 L/kg) following the method of Franco & Trapp (2008, 2009, 2010) (BASF SE, 2021).
Referring to the charged molecule at pH 7, the substance is not expected to adsorb to the solid soil phase
Henry´s Law Constant
The HLC for 3,5,5-trimethylhexanoic acid was estimated to be 0.408 Pa*m3/mol at 25°C (BASF SE, 2021), indicating that no volatilization from water surfaces into the atmosphere is expected.
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.
