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

No effects of the test substance on terrestrial organisms are expected.

Key value for chemical safety assessment

Additional information

No studies on long-term terrestrial toxicity are available for this substance. Due to the high Koc a considerable adsorption to sediment and soil is indicated. However, 2,2-bis[[(1-oxopentyl) oxy]methyl]propane-1,3-diyl divalerate (CAS-No.15834-04-5) has been shown to be readily biodegradable. Furthermore, basic data of a terrestrial plant toxicity test (short-term, OECD 208) with the read-across substance Fatty acids, C14-18 and C16-18 unsatd., triesters with trimethylolpropane (CAS 68002-79-9) is available, indicating no toxicity (NOEC = 300-1000 mg/kg soil dw, LOECs = 1000 mg/kg soil dw). In addition, Fatty acid esters are metabolised in Fatty acids and alcohols. These components occur in sediment and soils naturally, are part of physiological pathways and can be used as energy source. The enzyme carboxylesterase is omnipresent in the environment, readily degrading this test substance. Thus, toxic effects caused by the metabolites of fatty acid esters are implausible.

In conclusion, due to a) the observed absence of toxicological effects on aquatic organisms, b) the lack of chronic exposure and c) the, acknowledged metabolisation of fatty acid esters, toxic effects to terrestrial organisms can be excluded.
