Description of key information

A log Koc of 0.96 (9.1 l/kg) can be taken as representative for MTBE

Key value for chemical safety assessment

Koc at 20 °C:
9.1

Additional information

The organic carbon-water partitioning coefficient (Koc) calculated from the octanol-water partition coefficient (log Kow = 1.06) using the equation from the TGD (predominantly hydrophobics) is 9.1 l/kg (log value = 0.93). This predicted value is used in the assessment.
