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.

In a CO2- Headspace test according to ISO 14593 which is identical to OECD 310 (Ready Biodegradability - CO2 in sealed vessels) ethyl acrylate was readily biodegradable. After 28 days a biodegradation degree of 90 - 100% (TIC/ThIC) was determined (BASF AG, 2005). The test substance does not fulfill the criteria for persistency as outlined in Annex XIII of the REACH legislation of December 2006.

The experimental log Pow of Ethyl acrylate is of 1.18 (25 °C) indicates a low potential for bioaccumulation. This estimation is supported by a BCF value calculated by Q(SAR) data using BCFWIN v2.17 (BCF = 2.0) (BASF SE 2008), therefore it does not fulfill the criteria for bioaccumulation as outlined in Annex XIII of REACH legislation of December 2006.

The aquatic toxicity of the six acrylic esters (methyl, 2-ethylhexyl, ethyl, n-butyl, isobutyl, and tert-butyl acrylate) is evaluated as a category. The availabel data indicates an acute toxicity at the same order of magnitude across all three trophic levels for all acrylate esters within the category. The chronic toxicity has been assessed on alga and inverterbrates, with NOEC>0.01mg/L at both trophic levels. A 21-day chronic life-cycle study with Daphnia magna is available with ethyl acrylate with a respective NOEC of 0.19 mg/L, 21d=NOEC for nBA and 2EHA are 0.136 mg/L and 0.85 mg/L respectively. In addition, several NOEC values from studies in algal species are available ranging from 0.45 to 3.85 mg/L. Data for ethyl acrylate are conclusive and not sufficient for classification as a CMR. Further the substance is not classified as R48 nor STOT RE. This data supports the conclusion that Ethyl acrylate does not fulfill the criteria for toxicity as outlined in Annex XIII of REACH legislation of December 2006.
