Description of key information

For the test item the Log Pow -1.01 is used as key value for the CSR.

Key value for chemical safety assessment

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

Additional information

In a reliable guideline study the log Pow of the test item was determined to be -1.01 (Endpoint study record WoE_Partition coefficient 2010).

A similar value is reported in a review article (Endpoint study record WoE_Partition coefficient QSAR 1994). This value is probably related to the free ethenesulfonic acid. According to a (Q)SAR estimation the log Pow for the sodium salt is -4.17 (Endpoint study record WoE_Partition coefficient QSAR 2009).

To cover all potential grades of neutralisation log Pow -1.01 was choosen as the key value for CSR.
