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 physicochemical properties of the substance indicate that it can be expected to have a low potential for adsorption
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted since the substance is expected to have a low potential for adsorption (Log Kow < 3). - Reason / purpose for cross-reference:
