Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In general, absorption of alcohol and secondary aliphatic ketones is expected to occur rapidly in the tract gastrointestinal.
The possible metabolic reactions involved in the biotransformation of secondary ketones are:
(i) ketone reduction to the corresponding secondary alcohol, with subsequent excretion in the urine or in the bile as conjugate of the acid glucuronide;
(ii) omega oxidation of short-chain ketones (carbon atoms <5) or group oxidation terminal methyl and subsequent oxidation to produce an alpha-keto-carboxylic acid;
(iii) oxidation of doubles ties.
A
rabbit study showed that about 41% of 2-Eptanone given orally is
eliminated with urine in the form of conjugated glucuronic acid
(heptil-2-glucuronide). More
recent studies have shown that 2-Heptanone can be transformed into
hydroxyketone, subsequently transformed into heptane-2,6-dione via
oxidation.
