Description of key information

The effect concentration value after 3h of exposure to the analogue Pentaerythritol, ethoxylated, esters with acrylic acid  (CAS N. 51728-26-8)  was thus: EC50 > 100 mg/L. 

Key value for chemical safety assessment

Additional information

The study assessing the toxicity of Pentaerythritol, ethoxylated, esters with acrylic acid (CAS N. 51728-26-8) to freshwater microorganisms (domestic activated sludge) was used as worst case to fill by read-across the endpoint "Toxicity to microorganisms" of the test item. The effect concentration value after 3h of exposure was thus: EC50 > 100 mg/L.
