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 of1,2,3-propanetriyl trioleate (CAS No. 122-32-7) 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 toxicity data from a suitable read-across substance (Glycerides, C14-18 and C16-18 unsatd. mono-, di- and tri- (CAS No. 91052-28-7) in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5) are available. In this test performed according to OECD 207, no effects on survival or biomass of Eisenia fetida were reported, leading to a NOEC(14 d) ≥ 1000 mg/kg dw (Moser (2012)).

 

1,2,3-propanetriyl trioleate 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 or chronic toxicity to aquatic organisms. 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.
