Description of key information

The Log Pow of sulfolane at 20°C and a pH of 7 is <0.0.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

A study by STL Runcorn (2006) is available for this endpoint. The Log Pow of sulfolane at 20°C and a pH of 7 is < 0.0. This GLP-compliant study followed a standard guideline and is considered reliable and adequate for assessment.

The estimated Log Pow of sulfolane is -0.24 calculated from a QSAR model (KOWINN V1.67). This is supported by an experimental value in the QSAR dataset of -0.77.
