Description of key information

Based on the results, the calculated log Koc of the substance is to be higher than 10.

Key value for chemical safety assessment

Koc at 20 °C:
10 000 000 000

Additional information

"Should read: logKoc > 10"

The substance is insoluble or only poorly soluble in water. Even using a co-solvent, the test item immediately precipitates after contact with water. Therefore, an experimentally determination of the adsorption coefficient according to OECD TG 121 is not possible. Alternatively the adsorption coefficients were calculated using the software KOCWIN v2.00 owned by the U.S. Environmental Protection Agency on the basis of the structural formula of the test item components and possible hydrolysis products. Based on the results, the log Koc of the substance is expected to be higher than 10, indicating a high adsorption potential.
