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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACH Annex VIII, information requirement 9.3.1 (adsorption/desorption screening), a study does not need to be conducted if, based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol-water partition coefficient). The partition coefficient for the substance was determined to be 0.5 in a guideline and GLP-compliant study. It is therefore considered justified to omit testing for this endpoint.
