No data on long-term toxicity to fish is available. Considering all relevant ecotoxicological information available, long-term toxicity for fish is not expected.
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.
