Description of key information

The calculated log n-octanol water partition coefficient for Santicizer 261A is 5.75 at 20°C.

Key value for chemical safety assessment

at the temperature of:
20 °C

Additional information

Reliable experimental partition coefficient data is not available for Santicizer 261A. A log Kow of 5.75 has been calculated using a QSAR KOWWIN (USEPA, 2008). Santicizer 261A is in the domain of this QSAR. This value is supported by read-across from DEHP (ECB, 2008), DINP (ECB, 2003) and DIDP (ECB, 2003), which have a log Kow range of 7.5 -8.8. This is supported by a Kow value of 1170 from company data.
