Additional information

The acute toxicity of 2-dimethylaminoethyl acrylate to aquatic invertebrates was investigated in three studies. The MOE Japan (1997) reported a EC50 (48h) of 9.92 mg/L to Daphnia magna using a semi-static test system according to OECD guideline 202. In another study from the BASF AG a EC50 (48 h) of 24.9 mg/L was measured using the same species. A similar result was found in a third study following also the OECD guideline 202 (EC50 (48h) = 24 mg/L). Since the test substance hydrolyses at pH7, the results of a investigation using a semistatic test system reflect more the toxicity of 2 -dimethylaminoethyl acrylate and not of the corresponding hydrolysis products. Therefore, based on the MOE study it can be concluded that with high probability 2-dimethylaminoethyl acrylate is acutely toxic to aquatic invertebrates.
