Based on the OECD screening tests OECD 301 F and OECD 301F,
Ethyleneglycol dimethacrylate (EGDMA) is considered to be readily
biodegradable (> 60 % biodegradation within 28 days) but failing the
10-day window. Hence, the substance is not readily biodegradable
according to CLP criteria.
However, no bioaccumulation is expected according to log Pow of
Based on the available and reliable short-term toxicity data for
fish [LC50 (96h): 15.95 mg/l], daphnia magna [EC50 (48h): 44.9 mg/l) and
algae [EC50: 17.3 mg/l]), EGDMA does not need to be classified for acute
toxicity to aquatic organisms (cut-off value >1mg/l) according to the
CLP Regulation EC No 1272/2008.
Chronic aquatic toxicity studies are available for daphnia magna
and algae indicating a NOEC for daphnia magna of 5.05 mg/l and NOEC for
algae of 6.93 mg/l. No chronic data are available for fish. Because
adequate chronic toxicity data are thus only available for two trophic
levels, additionally the short-term toxicity data of fish [LC50 (96h) of
15.95 mg/l] must be considered for the assessment of the long-term
Triggered by the acute fish data (L(E)C50 value in the range of
>10 to≤100 mg/l), EGDMA needs to be classified for chronic toxicity to
aquatic organism with Aquatic Chronic Category 3 according to CLP
Regulation EC No 1272/2008.
