Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

One aquatic toxicity study is available on the UVCB substance FAV-ES. The algae study yielded the following effect concentrations:

-      72h ErC50 > 100 mg/L (acute)

-      72h ErC10 > 100 mg/L (chronic); 72h NOEC = 18 mg/L

The following environmental fate data are available:

-      Log Kow > 6.2

-      Biodegradable, not fulfilling the conditions of ready biodegradability

CLP classification

Acute aquatic hazard

The acute aquatic toxicity value is > 1 mg/L. As a consequence, the substance is not to be classified for acute aquatic toxicity and the determination of an M-factor is not applicable.

Chronic aquatic hazard:

There is only adequate chronic toxicity information available on algae, together a long term on daphnia whose results were disregarded for the classification of this substance according to the justification enclosed in section 6.1.4 . QSAR information shows that, for each of the constituents, the estimated LC50/EC50 values are above the water solubility. Therefore based on the QSAR results, toxicity is not expected to occur up to the saturation concentration.

The performed tests on daphnia, present results of doubtful interpretation and a number of confounding factors. Some effects have been reported above the solubility limits and in the presence of co‐solvents that were themselves toxic at the used concentrations; furthermore they had a confounding impact on the surface tension and partition phase of some components of the substance.

The observed effects have been reported much above the solubility limit of most of the components, nevertheless the substance is not Readily Biodegradable and log Kow is higher than 4. As a consequence a precautionary classification as Aquatic Chronic 4 (Safety net) was adopted.
