Description of key information

A measured log Kow value of -0.7 is reported for the C8 analogue. This is used as a worse case for the substance. 

Key value for chemical safety assessment

Log Kow (Log Pow):
-0.7
at the temperature of:
20 °C

Additional information

The log Kow measured for the C8 alkane sulfonate using the shake flask method was -0.7. This value is taken to represent a worse case for the substance and the other main constituent, the C6 alkane sulfonate, is expected to have a lower log kow due to the shorter alkyl chain length.
