Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

No experimental data evaluating the toxicity of Glycerides, C8-21 and C8-21-unsaturated, mono- and di-, acetates (CAS No. 97593-30-1) to arthropods are available. The standard information requirements set in Annex IX of Regulation (EC) No. 1907/2006, Column 2, 9.4, state that short-term toxicity tests on invertebrates should be available. Since earthworm toxicity data are available, showing no toxicity, testing on terrestrial arthropods is not deemed necessary.


Earthworm tests conducted on two analogue category members are used as read-across (in accordance with Regulation (EC) No. 1907.2006, Annex XI, 1.5). Both studies were performed according to OECD 207, showing no effects on survival or biomass of Eisenia fetida after 14 days, leading to NOEC values (14 d) ≥ 1000 mg/kg dw (limit tests) (Muckle, 2012; Moser, 2012).


Glycerides, C8-21 and C8-21-unsaturated, mono- and di-, acetates is readily biodegradable. Therefore, rapid and ultimate degradation in the environment, including soil, can be expected. Chronic exposure of terrestrial organisms is thus very unlikely. Furthermore, this substance did not show acute toxicity to aquatic organisms (fish, aquatic invertebrates and algae) up to a nominal loading rate of 100 mg/L or chronic toxicity up to 10 mg/L (nominal, loading rate). These results indicate no toxicity to terrestrial organisms is expected either.


Based on the available information, the chemical safety assessment according to Regulation (EC) No. 1907/2006, Annex I, does not indicate the need to conduct further tests on terrestrial arthropods.
