Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Acute toxicity:

Fish are the most sensitive species to the toxic effects of allyl methacrylate with an acute EC50 of 0.61 mg/L. Based on the results obtained in the aquatic toxicity studies, allyl methacrylate has to be classified Aquatic acute toxic cat.1 (H400: Very toxic to aquatic life.) according to Regulation (EC) No 1272/2008 (CLP).

Chronic toxicity:

One long-term study in freshwater invertebrates is available for allyl methacrylate. The 21-d EC10 based on reproduction is 0.272 mg/L (95 % c.l. 0.130 – 0.402 mg/L). As allyl methacrylate is readily biodegradable the substance is classified as aquatic chronic cat. 3 (H412: harmful to aquatic life with long lasting effects) according to Regulation (EC) No 1272/2008 (CLP).
