Additional information
PNEC freshwater, marine water and intermittent release can be derived based on studies on acute toxicity of three trophic levels with toxicity to alga showing the lowest effect. PNEC sediment and soil were derived using the equilibrium partitioning method. There are no data indicating a hazard to air and due to the low log Kow there is no potential for bioaccumulation via secondary poisoning and no PNECs need to be derived.
Conclusion on classification
The lowest effect was determined with the study on acute toxicity to alga (149 mg/L). The substance has a very low log Kow of´-1.12, a very high water solubility of 10000 mg/L (soluble in each ratio) and is readily biodegradable.
Based on these data the substance is not classified acoording to EC No. 1272/2008 criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
