Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Among all data available, a toxic effect was observed for the three aquatic trophic levels. The fish Brachydanio rerio (now Danio rerio) is the most sensitive species with a 96h-LC50 at 13 mg/L. For the algae Pseudokirchneriella subcapitata, the 72h-ErC50 was determined to be 14 mg/L, and for the aquatic invertebrates Daphnia magna, the 48h-EC50 was determined to be 18 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 combined 28 -day repeated dose toxicity study performed on the read-across substance was used to derive the PNECoral.

Environmental fate and pathways:

The registered substance is readily biodegradable (78.56% biodegradation after 28d and satisfied the 10 -d window criterion in an OECD Guideline 310 study), therefore it is not considered to be persistent. In addition, the registered substance has a medium mobility in soils (according to P.J. McCall et al., 1980) with a predicted Koc value at 191.4 L/kg (log Koc = 2.28) and is not considered to be bioaccumulative according to PBT criteria (log Kow of 3.7 therefore < 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; readily biodegradable; log Kow = 3.68.

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