Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Administrative data
Link to relevant study record(s)
- 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
Reference
Description of key information
Based on the low Partition coefficient value (log Pow: 0.357), the substance is expected to have a low potential for adsorption. Hence, the study was considered to be scientifically not necessary.
However, for the purpose of risk assessment, the adsorption coefficient (log Koc) was calculated to be 2.42 (Koc = 264.7 L/kg) using KOCWIN v 2.00 (EPISUITE v 4.10).
Key value for chemical safety assessment
- Koc at 20 °C:
- 264.7
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
