Description of key information

 Study conducted to generally recognised scientific standards

Key value for chemical safety assessment

Koc at 20 °C:
10.67

Additional information

In a KOCWIN v2.0 calculation (BASF SE, 2010) a log Koc of 1.03 was determined. Therefore, adsorption to the solid soil phase is not expected.

[LogKoc: 1.03]
