Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Glycerides, C16-18 (even numbered) mono- and di- and their citrates (EC 701-358-7) is characterised by low water solubility (129 µg/L at 20 °C; OECD 105, column elution method), low volatilization potential (vapour pressure < 0.00001 Pa at 20 °C, SPARC v4.6) and a moderate to high log Koc (2.51 – 8.04, KOCWIN v2.00; MCI method), indicating a high adsorption potential to soil and sediment particles. Furthermore, based on the available results from a structurally related read-across substance (in accordance with Regulation (EC) No 1907/2006 Annex XI, 1.5) which is characterized by a similar ecotoxicological profile and comparable structure, it can be concluded that Glycerides, C16-18 (even numbered) mono- and di- and their citrates is readily biodegradable according to OECD criteria (81% biodegradation after 28 days; OECD 301 F). Thus, it is expected that an extensive elimination of the substance in sewage treatment plants will occur.
According to the Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.7b (ECHA, 2017), the ready biodegradability of a substance can be considered indicative of rapid and ultimate degradation in most environments, including biological sewage treatment plants (STP) where the substance will be extensively removed in the primary settling tank and fat trap. Thus, only limited amounts will get in contact with activated sludge organisms in STPs. As a result of the moderate to high adsorption potential of the substance (log Koc = 2.51 – 8.04, KOCWIN v2.00; MCI method), a removal from the water column to a significant degree by adsorption to sewage sludge can be expected (Guidance on information requirements and chemical safety assessment, Chapter R.7b, (ECHA, 2017)). Thus, the concentration of the substance in effluents of conventional STPs is presumably marginal.
However, when released to the environment sediment and soil are expected to be the main compartments for environmental distribution. Due to ready biodegradability, abiotic degradation via hydrolysis is considered not relevant for the substance. Moreover, the substance is not volatile (vapour pressure < 0.00001 Pa at 20 °C, SPARC v4.6) and thus evaporation to the air and the transport through the atmospheric compartment is not likely. A bioaccumulation or biomagnification of Glycerides, C16-18 (even numbered) mono- and di- and their citrates through the food chain of the substance is not expected.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
