Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Dissociating properties:
no

Applicant's summary and conclusion

Conclusions:
Test item solutions with concentrations of approx. 5 g/L only generates conductivity values below 20 µS/cm . Due to this low conductivity only minor parts of the test item dissociates into ions.
The calculation of the dissociation constant was not possible.
The study was aborted.
