Additional information
The substance has a log Kow range of 0.3 to 0.4, is not readily or inherently biodegradable and has a water solubility of 0.12 g/L. The lowest toxicity was determined in a chronic study with daphnids giving a NOEC of 0.035 mg/L.
Conclusion on classification
The substance has a log Kow range of 0.3 to 0.4, is not readily or inherently biodegradable and has a water solubility of 0.12 g/L. The lowest toxicity was determined in a chronic study with daphnids giving a NOEC of 0.035 mg/L.
In accordance with Regulation EC No 1272/2008 the substance is classified as chronic category 1.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
