Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
During a preliminary test, the partition coefficient (n-octanol/water) (Pow) was estimated to be < 6x10-5 (log Pow < -4) as a quotient of the maximum solubility of the test item in n-octanol and water.
During a second preliminary test (simplified flask-shaking method), the test substance precipitated at the n-octanol-buffer interface. Because of this 'interface-effect' and because the flask-shaking method is only applicable for pure test substances (which the test item is not) and for -2 < log Pow < 4, the main study was not performed.
Key value for chemical safety assessment
