Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The substance is a complex mixture with an unknown composition or purity (UVCB) and the components of the substance were shown to have different solubility in aquous media. Therefore, all aquatic test were performed with WSF at a loading rate of 100 mg/l (based on the liquid suspension as received), the highest test concentration recommended in the OECD guidelines.

In none of the acute tests performed any effects were observed up to the maximum solubility in the tested media, thus LC50 and EC50 values exceed the measured concentrations (accounting for the water soluble components). For derivation of PNEC, however, the worst case was considered and the LC50 of the acute fish test (fish appeared to be the most sensitive species) was used for calculation. Also, PNEC sediment and soil were estimated using data (log Kow and Koc) of the soluble fraction of the substance as there is no information available on the insoluble fraction.

Conclusion on classification

Based on the results of the acute aquatic toxicity tests, i.e. no effects observed up to the maximum solubility in the test media, classification for the environment according to the CLP Regulation (EC) 1272/2008 and the DSD 67/548/EC is not justified.
