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.

Additional information

Under the analytical conditions used, HFE s-601 had a log Koc value of 3.8. The adsorption coefficient was determined to be 6500 L/kg. The log of the dimensionless Henry's Law constant (HLC) was measured as 3.4 at 22 °C. This corresponds to a value of 67 atm∙m³/mol. Given its high volatility, the majority of HFE s-601 released to the environment will reside in the atmospheric compartment.

This conclusion is supported by Mackay level III fugacity modeling, in which essentially all HFE s-601 remains in the atmospheric compartment after to air. A total of <0.005% of material will distribute to soil, water, or sediment.
