Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 effects up to the limit of water solubility (WS < 0.05 mg/L).
Key value for chemical safety assessment
Additional information
One study evaluating the toxicity of 1,2,3-propanetriyl trioleate(CAS No. 122-32-7) to aquatic microorganisms is available (Coenen, 1988). The test was performed according to the German method Assessment of hazardous substances in water, Determination of the acute toxicity in Bacteria, under GLP conditions.Pseudomonas putida cultures were exposed to the test substance for 18 hours in a static water regime at 25°C and effects on cell proliferation assessed (as the extinction of the monochromatic radiation at 436 nm in a 10 mm layer). After the exposure period, no inhibitory effects on cell multiplication could be observed up to the highest concentration tested and therefore, the EC50 (18 h) was determined to be > 0.8 mg/L (nominal concentration). Thus, no toxicity up to the limit of water solubility of 1,2,3-propanetriyl trioleate (< 0.05 mg/L) was observed.
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.
