CO2-Headspace test according to ISO 14593 which is identical to OECD 310
(Ready Biodegradability - CO2 in sealed vessels) methyl acrylate was
readily biodegradable. After 28 days a biodegradation degree of 90 - 100
% (TIC/ThIC) was determined. The 10-day-window criterion for ready
biodegradability was fulfilled (BAMM 2005). The test substance does not
fulfill the criteria for persistency as outlined in Annex XIII of the
REACH legislation of December 2006.
Methyl acrylate has ameasured
log Pow of 0.739 (25 °C) and a calculated BCF of 3.16 give no indication
for a potential for bioaccumulation. Therefore it does not fulfill the
criteria for bioaccumulation as outlined in Annex XIII of REACH
legislation of December 2006.
toxicity of the six acrylic esters (methyl, 2-ethylhexyl, ethyl,
n-butyl, isobutyl, and tert-butyl acrylate) is evaluated as a category.
The most sensitive test species in acute test wasDaphnia magnawith
EC50 between 1.3 and 8.74 mg/L. 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, and another in
progress with n-butyl acrylate. In addition, several NOEC values from
studies in algal species are available ranging from 0.45 to 3.85 mg/L.
The substance is not classified as a CMR and exhibits no long-term
effect other than respiratory irritation. Further the substance is not
classified as T, R48 nor Xn. This data supports the conclusion that
Methyl acrylate does not fulfill the criteria for toxicity as outlined
in Annex XIII of REACH legislation of December 2006.
