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
2-Ethylhexyl acrylate is acutely toxic to freshwater invertebrates.
EC50 (48 h) = 1.3 mg/L (measured), (Daphnia magna, OECD TG 202, static, closed system)
Key value for chemical safety assessment
Fresh water invertebrates

- Effect concentration:
- 1.3 mg/L
Additional information
BASF AG (2001) studied the effects of short-term exposure of Daphnia magna to 2-ethylhexyl acrylate according to OECD Guideline 202. The test was performed in a static and closed system. Six test concentrations ranging nominally from 3.13 mg/L to 100 mg/L were employed. The effect values were related to measured concentrations and are given as follows: EC50 = 1.3 mg/L; EC0 = 0.7 mg/L.
The other available tests were conducted without analytical monitoring and in open test systems. The volatility of 2 -EHA was not taken into consideration. Thus, these tests are not regarded valid for hazard assessment purposes.
In addition, a robust data set of acute studies is available from the other members of the acrylic ester category (methyl, ethyl, n-butyl, and tert-butyl acrylate).

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.
