Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Acute toxicity data of a structural and functional analogue (Pentaerythritol, ethoxylated, esters with acrylic acid; EC N. 500-111-9/CAS N. 51728-26) of the test substance are available for all four freshwater aquatic trophic levels (fish, aquatic invertebrates and algae). These data were used to fill by read-across the ecotoxicity endpoints of the test item dossier. In order to validate this read-across, a short-term toxicity test with the same species (Danio rerio) than for the analogue was performed.

Freshwater fish:

96h-LC50 values for Danio rerio were determined to be

7.9 mg/L for the test item,

1.76 mg/L for the analogue.

Freshwater invertebrates:

48h-EC50 value for Daphnia magna was determined to be 90.94 mg/L for the analogue.

Freshwater algae:

72h-EC50 value based on growth rate for Pseudokirchneriella subcapitata was determined to be higher than the highest concentration tested (100 mg/L) for the analogue.

Aerobic microorganisms:

3h-EC50value based on the respiration rate of domestic activated sludge was determined to be higher than the highest concentration tested (100 mg/L) for the analogue.
