Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Additional information

Conclusion on classification

A harmonised classification (CLH) is available on the registered substance with no aquatic hazard. However, based on data presented in this registration dossier, an aquatic hazard classification applied.


Classification related key information


Biodegradation in water: readily biodegradable, 83 - 100% (ThO2, DOC, test mat. analysis) in 28 days (OECD 301 C)


Bioaccumulation: no potential, log Kow = 0.9 at 25 °C (OECD 117)


 


Aquatic acute toxicity:


For fish: LC50 (96 h) = 4.6 mg/L for Oncorhynchus mykiss (EPA OTS 797.1400), RA


For aquatic invertebrates: EC50 (48 h) = 6.7 mg/L for Daphnia magna (OECD 202)


For algae: EC50 (72 h, cell number) = 4.5 mg/L for Selenastrum capricornutum (OECD 201) , RA


 


Aquatic chronic toxicity:


For fish: not available


For aquatic invertebrates: NOEC (21 d) = 0.19 mg/L for Daphnia magna (EPA OTS 797.1300), RA


For algae: not available


 


Classification according to CLP


Based on the data above, 2-methoxyethyl acrylate is considered to be rapidly biodegradable. The acute aquatic toxicity E(L)C50 values are > 1 mg/L for all trophic levels. Valid chronic toxicity data are available only for invertebrates with a NOEC > 0.1 to < 1mg/L (Daphnia magna). Therefore, 2-methoxyethyl acrylate has to be classified and labelled as environmental hazard Chronic Cat. 3 according to the Regulation (EC) No. 1272/2008 (CLP).


 


M-factor for acute aquatic toxicity: No classification for acute aquatic toxicity


M-factor for chronic aquatic toxicity: Not need to be assigned
