Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term aquatic toxicity data are available for each of the three freshwater trophic levels (fish, daphnia and algae). The observed L(E)C₅₀ values were:

96-hour LC₅₀ for freshwater rainbow trout (Oncorhynchus mykiss) = 4.2 mg/L

48-hour EC₅₀ for freshwater invertebrate (Daphnia magna) = 52 mg/L

72-hour growth rate EC₅₀ (ECr₅₀) for freshwater algae (Pseudokirchneriella subcapitata) = 36 mg/L

Studies on long term testing on aquatic invertebrates and long-term testing on fish have been waived as the chemical safety assessment demonstrates safe use of ethyl 2,3-epoxy-3-phenylbutyrate and indicates no need to investigate further the effects on aquatic organisms.
