Additional information

The UVCB substance WS405966 has very low water solubility (< 1 mg/l). In the acute aquatic toxicity tests performed with water accommodated fractions (WAFs) the substance did not exhibit toxic effects (L(E)C50) up to the limits of its water solubility in freshwater organisms of three trophic levels.

In none of the studies performed according to the REACH regulation Annexes VII and VIII any adverse effects were observed up to and including the highest dose levels required by the test guidelines.

Conclusion on classification

Based on the results of the available studies no classification for environmental hazards is necessary according to European classification rules [Regulation (EC) 1272/2008].
