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
EC50 (48 h): > 100 mg/L for Daphnia magna (OECD 202)
Key value for chemical safety assessment
Additional information
One experimental study investigating the short-term effects of 2-(1-methylethoxy)ethyl acetate (CAS 19234-20-9) to aquatic invertebrates is available (Vryenhoef, 2012). The study was performed according to OECD 202 under GLP conditions with the water flea Daphnia magna. A preliminary range-finding study with four concentrations up to 100 mg/L did not result in any immobilized daphnia. Therefore, a confirmatory limit test with 100 mg/L was performed. No immobilization was observed in the definitive test as well. Thus, an EC50 (48 h) of > 100 mg/L (nominal) was derived. Measured concentrations were within the range of 80 - 120%. Therefore, the EC50 was based on the nominal concentrations only.
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.
