Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The effect loading rate value obtained for an analogue or the test item after 72h of exposure (EL50 (growth rate) > 100 mg/L) was used to fill by read across the endpoint "Toxicity to aquatic algae and cyanobacteria".

Key value for chemical safety assessment

Additional information

A study assessing the toxicity (growth rate) of Ethoxylated bisphenol A diacrylate (EC 701-362-9) to aquatic algae (Pseudokirchneriella subcapitata) was used as a worst case to fill by read-across the endpoint "Toxicity to aquatic algae and cyanobacteria" of the test item. The effect loading rate value after 72h of exposure was thus EL50 (growth rate) > 100 mg/L. The use by read-across of this data was supported by a study assessing the toxicity of another analogue (2 moles ethoxylated bisphenol A dimethacrylate, EC 939-702-5) to the same species. The effect loading rate value after 72h of exposure was also EL50 (growth rate) > 100 mg/L.
