Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Valid acute studies based on international guidelines are available for the three aquatic trophic levels (algae, aquatic invertebrates and fish). Among all data available, a toxic effect was observed for the three aquatic trophic levels.

For aquatic invertebrates Daphnia magna, a 48h-EC50 value of 21.7 mg/L was determined based on analytically confirmed nominal concentrations.

For fish, Danio rerio, the 96h-LC50 value was determined to be 23.0 mg/L based on analytically confirmed nominal concentrations.

For the algae Pseudokirchneriella subcapitata, the most sensitive organisms, an 72h-ErC50 and an 72h-EC10 values based on growth rate were determined to be 12.0 (11.1 - 13.7) mg/L and 8.7 mg/Lrespectively, based on measured concentrations (geometric mean of T0 and T72 h).

In addition, the registered substance was not toxic to activated sludge from a municipal sewage treatment plan up to the nominal concentration of 10 mg/L (NOEC value) and an EC10 value of 24.4 mg/l was determined based on inhibition of total respiration.

Additional information

Although not requested under REACH Annex VII, the vertebrate acute fish study was performed to comply with worldwide regulations to allow notification in other countries.
