Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Aquatic acute toxicity was assessed at 3 trophic levels; fish, aquatic invertebrates (Daphnia) and aquatic plants (algae). The respective EC50/LC50 values for fish, Daphnia and algae, indicated the test material was moderately toxic to the aquatic environment. The aquatic invertebrate Daphnia magna were determined to be the most sensitive species with a 48 hour EC50 value of 1.7 mg/L with fish and algae providing values of 37 mg/L (96 hour LC50) and 30 mg/L (72 hour ErC50), respectively. Due to the lack of chronic data, acute aquatic toxicity data in combination with biodegradability data, is used for the determination of classification and labelling under the CLP regulation (1272/2008, as amended). Based on the information available, the test material is considered to be classified as Aquatic Chronic 2 (H411) under the CLP regulation.
The test material also has a low partition coefficient (Log Kow -1.35), indicating that bioaccumulation is not expected in the aquatic environment. No toxicity was observed in the activated sludge respiration inhibition test, indicating low potential for toxicity to sewage treatment plant micro-organisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
