Additional information
Aquatic toxicity:
Valid acute studies based on international guidelines are available for the three aquatic trophic levels (algae, aquatic invertebrates and fish) and toxic effect were observed.
For the fish, Danio rerio, the 96h-LC50 value was determined at 8.3 mg/L based on geometric mean measured concentrations. For the algae, Pseudokirchneriella subcapitata, the 72h-ErC50 and 72h-ErC10 values based on growth rate were determined at 4.85 and 2.26 mg/L, respectively, based on geometric mean measured concentrations.For the aquatic invertebrates, Daphnia magna, the 48h-EC50 value was determined at 2.30 mg/L based on geometric mean measured concentrations. In addition, the registered substance was not toxic to microorganisms from activated sludge of a wastewater treatment plan up to the nominal concentration of 100 mg/L.
Environmental fate and pathways
The registered substance is not readily biodegradable but partially and primary biodegradable. In addition, the substance have a low mobility in soils with a log Koc value at 3.05 (Koc = 1122). In addition, with a log Kow value at 3.89, the substance is not considered to be bioaccumulative according to CLP (< 4).
Conclusion on classification
No harmonised classification is available on the registered substance.
1 < Lowest L(E)C50 value < 10 mg/L; EC10 algae > 1 mg/L; not rapidly degradable; log Kow < 4.0
Classification according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP):
The registered substance is classified as Aquatic Chronic 2 for the environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
