Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The weighted partition coefficient of the test item was determined to be 4.49 * 10E4 with a weighted log10 Pow of 4.65 (OECD 117 and EU Method A.8).

Additional information

The n-octanol/water partition coefficient was determined using the HPLC method, designed to be compatible with OECD Guideline 117 and Method A8 of Commission Regulation (EC) No 440/2008 of 30 May 2008. Since some components of the test item had a dissociation constant within the environmentally relevant pH range, they were tested in a non-ionised form, and the pH of the mobile phase was adjusted to 3. The overall result was calculated as a weighted partition coefficient as opposed to a range.
