Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The distribution in a sewage treatment plant (STP) has been estimated using the SimpleTreat model (implemented in EUSES 2.1.2), see Table below:

All constituents of the registration substance have very high Henry’s Law constants and high log Kow/log Koc values. They are not expected to undergo any significant biodegradation.
For HMDS, air is the main compartment to which it is expected to partition in a sewage treatment plant. Some partition to sewage sludge and water is expected, and therefore potentially to soil/sediment compartments in the environment.
L3 is expected to partition mainly to air and sludge in a sewage treatment plant, with partition to water also being significant.
Sludge is the main compartment to which L4 and L5 are expected to partition in a sewage treatment plant, with partition to air and water also being significant.
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.
