Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In aqueous media the components of EUF are hydrolysed. Due to this rapid degradation in the water phase, an experimental determination of the distribution coefficient is not possible. Considering the chemical structure of the hydrolysis products, they are expected to exert only very low to weak adsorption to soils or sediments. Therefore, an experimental study on adsorption of EUF and its constituents in soils and sediments is scientifically not justified.

Using the log Pow of 1 as a worst-case assumption and the recommended QSAR equation for alcohols described in TGD (EC 2003, part III, chapter 4.3.2, p. 24), the Koc is calculated to be 7.76 L/kg.
