Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

No experimental data evaluating the toxicity of Glycerides, C14-18 and C16-18 unsaturated, mono-, di- and tri- (CAS No. 91052-28-7) to terrestrial plants are available.The test substance is characterized by a log Kow (> 4.65), indicating high potential for adsorption to soil particles. Tests with soil-dwelling organisms that feed on soil particles are therefore most relevant for the evaluation of soil toxicity of Glycerides, C14-18 and C16-18 unsaturated, mono-, di- and tri- (Guidance on information requirements and chemical safety assessment, Chapter R7.c (ECHA, 2008)). Due to the low water solubility and high adsorption potential of this substance, it is not expected to be found in the soil pore water, and uptake by plants is therefore highly unlikely. On the other hand, the Guidance on information requirements and chemical safety assessment, Chapter R7.c states that earthworm testing allows potential uptake via surface contact, soil particle ingestion and pore water, while plant exposure will be largely via pore water (ECHA, 2008). Therefore, earthworm was chosen as the most suitable organism to assess the terrestrial toxicity of this substance.The study conducted with Eisenia fetida according to OECD 207 showed no effects on survival or biomass, leading to a NOEC (14 d) ≥ 1000 mg/kg dw (Moser, 2012).

 

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 plants.
