Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Secondary poisoning is not considered a relevant route of exposure for birds; therefore, toxicity to birds testing is waived for 2-hydroxyethyl methacrylate.

Key value for chemical safety assessment

Additional information

Assessing the toxicity of 2-hydroxyethyl methacrylate to birds is not necessary since a large mammalian data set is available. This data set documents the effects of 2-hydroxyethyl methacrylate on terrestrial vertebrates. In addition, 2-hydroxyethyl methacrylate is readily biodegradable and has a very low potential for bioaccumulation (log Pow = 0.42); therefore, secondary poisoning is not considered a relevant route of exposure for birds. If necessary, the available mammalian data can be used in place of bird toxicity studies to develop a PNECoral for secondary poisoning. Thus, toxicity to birds is waived for 2-hydroxyethyl methacrylate.
