Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic toxicity:

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. The fish Danio rerio is the most sensitive species with a 96h-LC50 value at 52.0 mg/L based on analytically confirmed nominal concentration. For the algae Pseudokirchneriella subcapitata, the 72h-ErC50 and 72h-NOEC values based on growth rate were determined to be greater than the highest tested concentration 67.9 mg/L and 16.6 mg/L, respectively, based on geometric mean measured concentrations. For the aquatic invertebrates Daphnia magna, the 48h-EC50 value was determined to be 108 mg/L based on analytically confirmed nominal concentration. In addition, the registered substance was not toxic to activated sludge of a municipal sewage treatment plant up to the nominal concentration of 100 mg/L.

Sediment, terrestrial toxicity and hazard for predators

In the absence of any ecotoxicological data for sediment-dwelling/soil organisms, the PNEC sediment/soil were calculated using the equilibrium partitioning method (EPM). Furthermore, no toxicity studies reporting the secondary poisoning effects on bird were available, therefore the 28-day toxicity study on rats performed on the registered substance was used to derive the PNECoral.

Environmental fate and pathways:

The registered substance is considered readily biodegradable and therefore is notPersistent (P) or very Persistent (vP) in the environment.

Also, the registered substance is considered highly mobile in soils with a log Koc values at 2.0 for soil (Koc = 100) and 2.1 for sewage sludge (Koc = 126), and with a log Kow value at 3.32, the substance is not considered to be bioaccumulative according to CLP (< 4.0) and PBT criteria (< 4.5).

Conclusion on classification

No harmonised classification is available on the registered substance.

10 < lowest E(L)C50 value < 100 mg/L; EC10 or NOEC algae > 1 mg/L; rapidly biodegradable; log Kow = 3.32.

Classification according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP): The registered substance is not classified for the environment.
