Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Three acute experimental studies and two QSAR predictions are available to assess the aquatic toxicity of the registered substance.

The two experimental studies, performed on aquatic invertebrates Daphnia magna and the algae Desmodesmus subspicatus respectively, were not considered reliable due to major methodological deficiencies and/or insufficient information provided on the methodology used. Therefore, QSAR predictions for these endpoints were performed using iSafeRat® High-Accuracy-Quantitative Structure-Activity Relationship (KREATIS, 2019). Toxic effects were predicted on aquatic invertebrates and algae in acute conditions. For daphnid, the 48h-EC50 value was predicted at 0.98 mg/L. For algae, the 72h-ErC50 value was predicted at 2.6 mg/L.

Finally, the experimental study performed on fish Danio rerio was considered reliable (with restrictions). The 96h-LC50 value was determined at 2.1 mg/L, based on analytically confirmed nominal concentrations.

Environmental fate and pathways:

The registered substance is not readily biodegradable (no biodegradation after 28 days in the OECD 301F key study, same result after 60 days). There, in the absence of other studies, the substance can be considered potentially Persistent (P) or very Persistent (vP) in the environment. In addition, with a log Kow value at 4.77, the substance is considered to be bioaccumulative according to CLP (> 4.0) and PBT criteria (> 4.5).

Conclusion on classification

No harmonised classification is available.

Data available:

- Lowest E(L)C50 value < 1 mg/L, more precisely between 0.1 and 1 mg/L (M-factor = 1);

- No chronic value;

- Not rapidly degradable;

- log Kow > 4.

Classification according to the Annex I of the Regulation (EC) No 1272/2008 (CLP):

The registered substance is classified as Aquatic Acute 1 and Aquatic Chronic 1 for the environment, with a M-factor = 1 (based on acute toxicity values).
