Description of key information

The Koc is required for exposure assessment and derivation of PNECsoil and PNECsediment. In the absence of measured data, the Koc has been estimated from Kow.

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

Regression model: Log Koc = 0.81 Log Kow + 0.1

Applicability Domain: chemical class "predominantly hydrophobics"; Log Kow range of 1 to 7.5.

Reference: ECB TGD on Risk Assessment, Part III, Chapter 4 (2003), available at

The log Kow for DIMETOL is 3.0 giving an estimated Log Koc of 2.53 (equivalent to Koc of 339)
