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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

The
potential environmental distribution of isoundecanol in 4 environmental
compartments as calculated using a fugacity model, the Mackay Level III,
under the default emission scenario (1000 kg/h into each of air water
and soil compartments) with half-life data set (see above) is shown
below:
Relative distribution when released (see half-life values above):
Air
2.5%
Soil
70.5%
Water
26.8%
Sediment
0.2%
Applicant's summary and conclusion
- Conclusions:
- The Mackay Level III equilibrium model estimates that Alcohols, C9-C11, branched will partition largely to the soil compartment (approximately 70%), followed by the water (approximately 27%) and minimally to the air and sediment compartments (2.5 and 0.2%, respectively), based on all available measured data.
- Executive summary:
The Mackay Level III equilibrium model estimates that Alcohols, C9-C11, branched will partition largely to the soil compartment (approximately 70%), followed by the water (approximately 27%) and minimally to the air and sediment compartments (2.5 and 0.2%, respectively), based on all available measured data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
