Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The water solubility of the test material has been determined to be 148 g/L of solution at 20.0± 0.5°C. The pH of the test media showed no significant effect on the water solubility of the test material in the range pH 4 to 9. Temperature showed an effect on the water solubility of the test material which increased with increasing temperature; but was not significant over the temperature range 10°C to 30°C.

Key value for chemical safety assessment

Water solubility:
148 000 mg/L
at the temperature of:
20 °C

Additional information

The water solubility was determined using the shake flask method with LC detection.

The linearity of the detector response with respect to concentration was assessed over the nominal concentration range of 0 to 43 mg/L in reverse osmosis water. This was satisfactory with a correlation coefficient of 0.99 being obtained. Sample filtering was shown not to remove test material from solution by analytical comparison of a filtered and unfiltered sample
