Description of key information

Using the HPLC method the adsorption coefficient (Koc and Log Koc) of the test item was estimated to be 488 and 2.69, respectively.

Key value for chemical safety assessment

Koc at 20 °C:
488

Additional information

The purpose of this study was to estimate the adsorption coefficient Koc of the test item using HPLC in accordance with OECD guideline 121 and EU method C.19. This method is applicable for substances, which have log Koc value ranging from 1.5 to 5.0. The log Koc and Koc of the test substance were estimated to be 2.69 ± 0.003 (95 % confidence interval) and 488 ± 3.6 (95 % confidence interval), respectively.

[LogKoc: 2.69]
