Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Relevant data available for aquatic toxicity are listed:
1. 48-h EC50 (invertebrates) : > 100 mg/L based on analytically confirmed nominal concentrations, freshwater, OECD TG 202, 2021
2. Read-Across: source data : Reaction products of 2-hydroxyethyl methacrylate and diphosphorus pentaoxide :
72-h ErC50 (aquatic algae; growth rate): = 165 mg/L based on TWA concentrations (or > 160 mg/L nominal), 72 hour, freshwater, OECD TG 201, 2004
72 -h ErC10 (aquatic algae; growth rate): = 49 mg/L based on TWA concentrations (or 92 mg/L nominal), 72 hour, freshwater, OECD TG 201, 2004
72-h NOErC (algae; growth rate): = 39 mg/L based on TWA concentrations (or 80 mg/L nominal), 72 hour, freshwater, OECD TG 201, 2004
Therefore:
72-h ErC50 (aquatic algae; growth rate): target : > 100 mg/L (or 165 mg/L) based on TWA concentrations, 72 hour, freshwater, OECD TG 201, 2021
72-h ErC10 (algae; growth rate) : target : = 49 mg/L based on TWA concentrations, 72 hour, freshwater, OECD TG 201, 2021
72-h NOErC (algae; growth rate): target : = 39 mg/L based on TWA concentrations, 72 hour, freshwater, OECD TG 201, 2021
3. Read-Across: source data : Reaction products of 2-hydroxyethyl methacrylate and diphosphorus pentaoxide :
96-h LC50 (fish) : > 100 mg/L based on analytically confirmed nominal concentrations, OECD TG 203, 2004
Therefore:
96-h LC50 (fish) : target : > 100 mg/L based on analytically confirmed nominal concentrations, freshwater, OECD TG 203, 2021
4. ASRIT:
Total Respiration Inhibition:
3h-EC50 = > 270 mg/L (nominal), 20 °C
3h-EC10 = - mg/L (nominal), 20°C
NOEC = 270 mg/L(nominal), 20 °C, OECD TG 209, 2021
Heterotrophic Respiration Inhibition:
3h-EC50 = > 270 mg/L (nominal), 20 °C
3h-EC10 = - mg/L (nominal), 20 °C
NOEC = 270 mg/L(nominal), 20 °C, OECD TG 209, 2021
Nitrification Inhibition:
3h-EC50 = > 810 mg/L (nominal), 20 °C
3h-EC10 = - mg/L (nominal), 20 °C
NOEC = 810 mg/L(nominal), 20 °C, OECD TG 209, 2021
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
