Description of key information

Koc >4.3 x 10⁵ and log Koc >5.63,  OECD 121 and EU Method C.19, Baltussen 2013b.

Key value for chemical safety assessment

Additional information

In the key study the adsorption coefficient of the test material was investigated in accordance with standardised guidelines by applying the HPLC method using soil-adsorption-reference data. The test material was compared to several reference compounds and the adsorption coefficient calculated. Under the conditions of this study, the Koc and log Koc values of the test material at neutral pH were >4.3 x 10and >5.63, respectively.

The adsorption profile of the substance has been sufficiently characterised in the screening test and further testing would not improve the risk assessment of the substance.
