Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The chemical safety assessment according to Annex I of Regulation (EC) No. 1907/2006 does not indicate the need to investigate further the long-term toxicity to fish. 

Key value for chemical safety assessment

Additional information

The chemical safety assessment according to Annex I of Regulation (EC) No. 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.

The available experimental studies on aquatic toxicity of fatty acids, C5-9 tetraesters with pentaerythritol (CAS 67762-53-2). to fish or experimental studies on any of the chosen read across substances the do not show any acute toxic effects up to the limit of water solubility. Furthermore, the long term test on the reproduction of daphnids also does not reveal any adverse effects.Asthere was no sign that fish are the most sensitive species 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 test with invertebrates. Hence due to animal welfare reasons and to avoid unnecessary vertebrate tests, no further long-term test with fish is required for fatty acids, C5-9 tetraesters with pentaerythritol (CAS 67762-53-2).

In addition,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.

Therefore, it can be concluded that chronic exposure of fatty acids, C5-9 tetraesters with pentaerythritol (CAS 67762-53-2) to fish is unlikely and that it would not pose a higher risk to fish than it does to daphnids.
