Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is characterized by a water solubility of < 1.51 mg/L at 20 °C (OECD 105), a vapour pressure of 0.588 Pa at 25 °C (EpiSuite v4.11) and a log Koc of 4.08 - 13.1 (EpiSuite v4.11). Thus, if the substance is released to the environment it has a high potential for adsorption to sediment and soil particles. Hydrolysis is not considered to be a relevant degradation pathway since QSAR calculations do not indicate a fast hydrolysis under environmental conditions. Moreover, sterical hindrance of the glycosidic bond by fatty acids does not allow for significant hydrolysis. Thus, the substance is considered to be hydrolytically stable in the environment. Significant biodegradation by activated sludge microorganisms is not expected. 19-28% degradation was recorded in a standard biodegradation study according to OECD 301D and 66.6% degradation was observed in an inherent biodegradation study according to OECD 302C. Thus, the substance is primary biodegradable but not readily biodegradable according to the OECD criteria. Even though the substance is stable in the environment, bioaccumulation is considered to be low based on the log Pow values of the different constituents of the UVCB substance.
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.
