Description of key information

No adsorption due to negative Log Kow

Key value for chemical safety assessment

Koc at 20 °C:
6.724

Additional information

In accordance with Column 2 adaptation statement of REACH Annex VIII and IX, adsorption/desorption screening and further studies on adsorption/desorption, information requirements 9.3.1 and 9.3.3, may be omitted since the log Kow value for the test substance is <3.0 (CSR sections 1.3 and 4.2.1) and has low potential for adsorption.
