Additional information
The substance did not show any signs of toxicity in acute aquatic toxicity tests on three trophic levels (daphnia, fish, aquatic plants) and also not towards sewage sludge microorganisms. Thus, currently no hazard is identified. However, due to the low water solubility and high log Pow and high adsorption coefficient adsorption to sediment and soil is likely and a PNEC freshwater/marine was derived in order to use it as input information for soil and sediment PNEC derivation via the partitioning method.
Conclusion on classification
In lack of toxicity to aquatic organisms the substance is not classifiable for acute aquatic toxicity nor for chronic aquatic toxicity category 1 to 3. However, due to lack of biodegradation and a high log Pow in combination with lack of water solubility, the substance is to be classified for chronic aquatic toxicity, category 4 (safety net classification), H 413, according to CLP (Regulation EC No 1272/2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
