Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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):
- -1.01
- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
