Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

adsorption / desorption: screening
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter
the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly

Description of key information

No study was required to determine adsorption/desorption coefficients for this substance. However, a screening exercise for assessing risk to soil and sediment organisms requires a Koc to be derived using equilibrium partitioning theory, therefore the standard algorithm for non-hydrophobic substances was used (see ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.16)

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

Koc was derived using the following calculations:

Koc = 1.26 x Kow0.81 / 1000

= 1.26 x 5.750.81 / 1000

= 0.01


Kow (n-octanol/water partition coefficient) = 5.75
