Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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). A toxic effect was observed for the three aquatic trophic levels.

Aquatic invertebrates, Daphnia magna, are the most sensitive species with a 48h-EC50 value at 1.1 mg/L based on time-weighted mean concentrations.

For the algae Pseudokirchneriella subcapitata, the 72h-ErC50 and 72h-ErC10 values based on growth rate were determined to be 2.6 and 1.5 mg/L, respectively, based on time-weighted mean concentrations.

For the fish, Danio rerio, the 96h-LC50 value was determined to be 4.07 mg/L based on the geometric mean of the measured concentrations.

For micro-organisms, the effect of the test item on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC50 value of greater than 100 mg/L.

Environmental fate and pathways:

The registered substance is not considered readily biodegradable and therefore it can be considered as a potential Persistent (P) in the environment.

Also, the registered substance is considered low mobile in soils with a logKoc values at 2.86 (Koc=724) and with a log Kow value at 3.12,the substance is not considered to be bioaccumulative according to CLP (< 4.0) and PBTcriteria(< 4.5).

Conclusion on classification

No harmonised classification is available on the registered substance. Nevertheless:

- the substance is not readily biodegradable,

- log Kow= 3.12

- For Daphnia and fish, 1 > lowest E(L)C50 value ≤ 10 mg/L; and for algae, 1> ErC50 ≤ 10 mg/L

Classification according to the Annex VI of the Regulation(EC) No 1272/2008 (CLP): The registered substance is classified for the environment as Aquatic Toxic Chronic 2.
