Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No toxicity up to the limit of water solubility (< 1 mg/L) is expected.
Key value for chemical safety assessment
Additional information
No reliable experimental data evaluating the toxicity of C12-C18 trialkyl glyceride (CAS 67701-26-2) to aquatic microorganisms are available. According to Regulation (EC) No. 1907/2006, Annex VIII, 9.1.4, column 2, this type of study does not need to be conducted if there are mitigating factors indicating that microbial toxicity is unlikely to occur, for instance if the substance is highly insoluble in water. Triglycerides, mixed decanoyl and octanoyl has a water solubility < 1 mg/L. The Guidance on information requirements and chemical safety assessment, Chapter R7.b (ECHA, 2012) states that once insoluble chemicals enter a standard STP, they will be extensively removed in the primary settling tank and fat trap and thus, only limited amounts will get in contact with activated sludge organisms.
Nevertheless, if such a contact takes place, the ready biodegradability test conducted for the suitable read-across substance Glycerides, tall-oil mono-, di-, and tri- (CAS No. 97722 -02 -6) (Schoeberl, 1993) showed that biodegradation of 79%) occurred after an exposure of 28 days. According to the Guidance on information requirements and chemical safety assessment, Chapter R7.b (ECHA, 2012), the assumption that the substance is not inhibitory to the microorganisms is implicit in ready biodegradability tests. If a substance shows good biodegradation in such a test, the tested concentration can be used as a NOEC value (in the case of Glycerides, tall-oil mono-, di-, and tri-, NOEC ≥ 98.27 mg/L).
Since no toxicity to aquatic microorganisms has been observed either in any other Glyceride category member, and considering the information above, it can be concluded that C12-C18 trialkyl glyceride (CAS 67701-26-2) will not exhibit toxicity to aquatic microorganisms.
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.
