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 11.3 mg/L based on analytically confirmed nominal concentrations. For the algae, Pseudokirchneriella subcapitata, the 72h- ErC50, 72h-ErC10 and 72h-NOECr values based growth rate are 55, 13 and 3.2 mg/L, respectively, based on time weighted average concentrations. As the ratio NOEC/LOEC is higher than 3.2, the NOECr for algae test is considered as unacceptable and 72h-ErC10 has been used as critical value. For the aquatic invertebrates, Daphnia magna, the 48h-EC50 value was determined to be 21 mg/L based on analytically confirmed nominal concentrations. 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.
Environmental fate and pathways
The registered substance is considered readily biodegradable and therefore is not Persistent (P) or very Persistent (vP) in the environment. Also, the registered substance is considered to have low mobility in soils with a log Koc values at 2.9 for soil (Koc = 820) , and with a log Kow value at 3.8, the substance is not considered to be bioaccumulative according to CLP (<4) 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=3.8
Classification according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP):
The registered substance is not classified 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.
