Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

The chemical safety assessment according to Annex I of Regulation (EC) No 1907/2006 indicates no need for further studies on terrestrial organisms. Thus in accordance with Regulation (EC) No. 1907/2006, Annex IX, Column 2, 9.4 further studies on the effects on terrestrial organisms do not have to be conducted. The substance is readily biodegradable and furthermore characterised by a low water solubility and high log Koc. Due to the expected environmental fate of the substance an exposure of terrestrial organisms is considered unlikely. Read-across data on the terrestrial toxicity of the analogue substance 2-ethyl-2-(((1-oxoisooctadecyl)oxy)methyl)-1,3-propanediyl bis (isooctadecanoate) (CAS 68541-50-4) to the earthworm Eisenia fetida determined no toxicity up to a test concentration of 10,000 mg/kg (NOEC (56 d) >10,000 mg/kg dw) . Based on the available information toxicity of Fatty acids, C18-unsatd., dimers, reaction products with fatty acids, C14-18 and C16-18-unsatd. and propylidynemethanol to terrestrial organisms is not expected.
