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

The physico-chemical properties of 1,2,3-propanetriyl triisooctadecanoate (CAS 26942-95-0) such as low water solubility (WS < 0.05 mg/L), low volatilization potential (VP <0.0001 Pa) and high adsorption potential (log Koc: 13.96), indicate that the substance may predominantly distribute to soil and sediment when released to the environment. According to the Guidance on information requirements and chemical safety assessment, Chapter R7.b (ECHA, 2012) once insoluble chemicals enter a standard sewage treatment plant, these substances are considered to be removed from the water column to a significant degree by adsorption to sewage sludge. Consequently, the release to surface waters, and thereby exposure of sediment and soil, is considered as marginally.
