Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Fatty acids, C18-unsaturated, 1,6 Hexanediol Diester (EC 947-912-3) is an UVCB substance. The substance is poorly soluble in water (WS: < 0.57 µg/L at 20 °C, pH 6.3). The Log Pow and log Koc values, estimated for two representative components of the UVCB, are >9. Based on experimental results from a standard biodegradation study, the substance is readily biodegradable according to guideline criteria (82.2% in 28 d; OECD 301B) and thus will be extensively removed from wastewater in conventional STPs. Abiotic degradation via hydrolysis is no relevant degradation pathway. Due to the low vapour pressure of the substance (VP: <0.0001 Pa at 20 °C) evaporation and subsequent transportation through the atmosphere is not likely. If the substance is released to the environment a distribution into sediment and soil is expected based on the substance characteristics.
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.
