Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
The Mackay Level III equilibrium model estimates that Alcohols, C7-9-iso-, C8-rich, will partition largely to the soil compartment (approximately 64%), followed by the water (approximately 33%) and minimally to the air and sediment compartments (2.5 and 0.1%, respectively), based on all available measured data.
Executive summary:

The Mackay Level III equilibrium model estimates that Alcohols, C7-9-iso-, C8-rich, will partition largely to the soil compartment (approximately 64%), followed by the water (approximately 33%) and minimally to the air and sediment compartments (2.4 and 0.1%, respectively), based on all available measured data.
