Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The terrestrial toxicity of Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates (CAS No. 91052-13-0) has been tested on the earthworm Eisenia fetida. The test substance is characterized by high log Koc values for its main components (3.7 – 4.8), indicating high adsorption potential. Tests performed with a soil-dwelling organism that feeds on soil particles is therefore most relevant for the evaluation of soil toxicity Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates. Furthermore, 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 and soil microorganisms exposure will be largely via pore water (ECHA, 2012). Therefore, earthworm was chosen as the most suitable organism to assess the terrestrial toxicity of this substance.

No mortality or significant weight changes were observed in the control and the treatments during the test period of 56 days. Furthermore, no significant effects in reproduction up to the highest test concentration were observed. Based on reproduction the NOEC (56 d) was determined to be 1000 mg/kg dw soil.


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.
