Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
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

Description of key information

Adsorption/desorption data are not available. According to column 2 of REACH Annex VIII the adsorption/desorption screening study does not need to be conducted as the substance has a low octanol water partition coefficient.

The adsorption/desorption (Koc) is calculated because the log Kow is < 3. Using the measured log Kow (2.6) and the default non-hydrophobics QSAR in EUSES (log Kow < 3): Koc = 10.47*(Kow)^0.52 the Koc is 235 L/kg and the log Koc 2.4. Based on this value it may be concluded that the substance has low potential for adsorption to solid surfaces.

Key value for chemical safety assessment

Koc at 20 °C:
