Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 does not indicate the need for long-term testing on fish species
Key value for chemical safety assessment
Additional information
No experimental data evaluating the chronic toxicity of Glycerides, C8-21 and C8-21-unsatd., mono- and di-, acetates (CAS No. 97593-30-1) to fish species are available. According to Regulation (EC) No. 1907/2006, Annex IX, Column 2, 9.1, long-term toxicity testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the effects on aquatic organisms. Glycerides, C8-21 and C8-21-unsatd., mono- and di-, acetates is readily biodegradable (83% in 28 days) and therefore, according to the Guidance on information requirements and chemical safety assessment, Chapter R.7b (ECHA, 2008), this substance will undergo rapid and ultimate degradation in most environments, including biological Sewage Treatment Plants (STPs). Based on this information, concentrations of the substance into the aquatic compartment from STP releases and therefore, the bioavailability to aquatic organisms, are expected to be low. The acute tests performed with fish (Weyers, 2007 and Richter, 2012), aquatic invertebrates (Weyers, 2007) and algae (Weyers, 2007) and the chronic test conducted with aquatic invertebrates (Richter, 2012) showed no adverse effects of the substance at the tested concentrations. Regarding the results of the acute tests performed on fish and aquatic invertebrates, there is no evidence showing that fish species will be more sensitive to the effects of Glycerides, C8-21 and C8-21-unsatd., mono- and di-, acetates than Daphnia magna. Due to this fact, the ready biodegradable nature of the substance, its lack of acute and chronic toxicity to aquatic organisms and considering animal welfare, long-term toxicity to fish species is not deemed necessary.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
