Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The assessment relies on both data on target substance, used as key study, and on Similar Substance 01, i.e. a different salification of target substance, used as supporting evidence. Details on the read across are reported in section 13.

In the key study, conducted according to OECD guideline 202, test substance resulted to be stable during the test period and no precipitation was seen. At 48 h of exposure, effect levels were found: EC10 = 0.0840 mg/l, EC50 = 0.0955 mg/l, EC100 = 0.316 mg/l.

Available data on Similar Substance 01 was used as supporting evidence, with an EC50 of 0.18 mg/l after 24 h of exposure.
