Additional information
THE UVCB substance WS400151 has very low water solubility (< 1 mg/l). In acute aquatic toxicity tests performed with water accomodated fractions (WAFs) the substance did not exhibit toxic effects (L(E)C50) up to the limits of its water solubility.
In a Daphnia reproduction test also no effects were observed up to the limit of water solubility. However, the NOELR in the algae test was determined at a loading rate (WAF) of 0.3 mg/l. This value was taken for derivation of PNEC values.
Conclusion on classification
The substance has to be classified as aquatic chronic 2 (H411) according to Regulation 1272/2008 and N, R51/53 according to Directive 67/548 based on its aquatic toxicity and and poor biodegradability.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
