Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Long-term toxicity to fish
Administrative data
Link to relevant study record(s)
Description of key information
No data on long-term toxicity to fish is available. Considering all relevant ecotoxicological information available, long-term toxicity for fish is not expected.
Key value for chemical safety assessment
Additional information
No experimental data on long-term toxicity to fish are available Hexanoic acid, 2-ethyl-, C16-18 alkyl esters (CAS No. 90411-68-0). The chemical safety assessment according to Annex I of Regulation (EC) 1907/2006 does not indicate the need to investigate further the long-term toxicity to fish. Thus, in accordance to Annex IX, column 2, no further long-term toxicity test to fish is proposed.
Based on the available data, no effects were observed in short-term studies with fish, aquatic invertebrates and algae. Moreover, no effects were observed in two chronic read across studies with Daphnia magna according to OECD 211 (NOELR/NOEC > 1 mg/L). As there was no sign that invertebrates are less sensitive than fish in the short term tests, it cannot be expected that a long-term test with fish will generate different results than the existing long-term data with invertebrates. Due to its ready biodegradability it is not likely that aquatic organisms are exposed to the test substance since it will be ultimately degraded in sewage treatment plants. Thus, based on the above mentioned results, it can be concluded that Hexanoic acid, 2-ethyl-, C16-18 alkyl esters (CAS No. 90411-68-0) does not show any chronic toxicity to fish up to the limit of water solubility. Hence due to animal welfare reasons and to avoid unnecessary vertebrate tests, no further long-term toxicity test with fish is required.
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).
