Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- the study does not need to be conducted because the physicochemical properties of the substance indicate that it can be expected to have a low potential for adsorption
- the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly
- other:
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with REACH Regulation (EC) No. 1907/2006 Annex VIII, column 2 section 9.3.1 the study does not need to be conducted based on structural assessment of the substance and measured physicochemical and environmental fate properties. The substance constituents do not contain functional groups associated with ionisation potential in environmentally relevant pH ranges and is not predicted to be surface active. The substance has a measured logarithmic n-octanol/water partition coefficient: < 3.0. On this basis it can therefore can be expected to have a low potential for adsorption. Additionally, the substance is readily biodegradable and the substance and its degradation products can be presumed to be ultimately degraded within a period of 28-days in the aquatic compartments (reference: OECD 301D, 2013 and OECD 301F, 2011). According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.15, July 2017 and Chapter R.7b: Endpoint Specific Guidance, June 2017) the study does not need to be conducted. - Reason / purpose for cross-reference:

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.
