Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There are no data available on bioaccumulation potential, oral, dermal or inhalation absorption rate.
Key value for chemical safety assessment
Additional information
3,5,5-trimethylhexanoic acid is expected to be rapidly absorbed after oral uptake. To all appearances it does not undergo ß-oxidation due to an un-even position of the methyl substitution. The metabolism is suspected to accur via chain hydroxylation and subsequent formation of ketoacid or dicarbonic acids, which are excreted into bile or urine or cleaved in the gut and undergo entero-hepatic circulation.
No noteworthy formation of 3,5,5-trimethylhexanoic acid is expected from the corresponding alcohol, because the latter is expected to be a poor substrate for alcoholdehydrogenase. Therefore, data from this substance are not relevant for the risk assessment of 3,5,5 -trimethylhexanoic acid (Semino, 1998).
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.
