Description of key information

Testing is scientifically unjustified as the substance is hydrolytically unstable. The estimated Koc of the main degradation product (IPA) is used in the hazard assessment and CSA when relevant.

Key value for chemical safety assessment

Koc at 20 °C:
1.53

Additional information

Testing is scientifically unjustified as this substance is hydrolytically unstable (half-life < 3 min; OECD 111). Therefore, the estimated Koc of the main degradation product (IPA) was calculated to be 1.53 L/kg. The value is estimated by using KOCWIN v.2 (US EPA 2012).

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.
