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.

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.
