Description of key information

Testing is scientifically unjustified as the substance reacts when in contact with water or moisture. The estimated Koc is used in the hazard assessment and CSA.

Key value for chemical safety assessment

Koc at 20 °C:
24.21

Additional information

Testing is scientifically unjustified as this substance reacts with water and moisture. Therefore, the estimated Koc of 24.21 L/kg is used as a key value in CSA. The value is estimated by using KOCWIN v.2.0 (US EPA 2012). The calculation estimates Koc based on the Sabljic molecular connectivity method (MCI) with improved correction factors. Metal (K) was removed to allow estimation via MCI.

This value is considered reliable with restrictions and used as a key value in CSA and to derive the PNECs to sediment and soil compartment by using equilibrium partioning method.
