Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A 10 mg/l nominal test substance concentration was prepared
by stirring for 72 hours. Measured concentrations in
centrifuged samples at 0h and 48h were < limit of detection
(0.03 mg/l). Analysis of non-centrifuged samples gave
variable results - 2.7, 2.7, 2.5 mg/l at 0h and 0.24, 0.41,
0.72 mg/l at 48h. No effects were observed so it can be
assumed that the test substance shows no effects up to its
limit of solubility.
