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 Multi constituent ester of pentaerythritol 2-ethylhexanoate. 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 up to the limit of water solubility were observed in short-term studies with fish and algae. Moreover, no effects were observed in a chronic study with Daphnia magna according to OECD 211 (NOEC > water solubility). 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. In addition, the ECHA Guidance on information requirements and chemical safety assessment, Chapter R.7b (ECHA, 2012b) states that “chronic fish toxicity testing is generally only necessary, when the P and B criteria are fulfilled” and this is clearly not the case. Thus, based on the above mentioned results, it can be concluded that Multi constituent ester of pentaerythritol 2-ethylhexanoate does not show any chronic toxicity to fish up to the limit of water solubility (< 0.05 mg/L). Hence due to animal welfare reasons and to avoid unnecessary vertebrate tests, no further long-term test with fish is required.
