Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Estimated based on individual solubilities:

log Pow= -1.60 to -1.0 at 23°C

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
23 °C

Additional information

The analytical method for the detennination is in agreement with the method that was agreed upon at the "Analytical Experts Meeting" of ETAD (Basel) on January 12,2005.

Because of high extinction coefficient ɛ in sulfuric acid (about 200 l/g*cm at 792 nm) and the very low solubility, an exact value for solubilities in water and in octanol will be not available.

In order to give an indication for a possible logPow value of the test item the estimation method based on the individual solubilities in octanol and in water was applied.
