Description of key information
Additional information
Fusel oil is highly soluble in water and has low adsorption potential (log Kow < 3). It is thus expected to mainly partition into the water phase. Despite the relatively high vapour pressure (57.26 hPa at 19.6 °C for ethanol, the most volatile constituent), evaporation from water into the atmosphere is either unlikely or is expected to be very slow, due to the low Henry’s law constants (0.50 - 1.68 Pa m3/mol).
Fusel oil is readily biodegradable, based on studies conducted with its main constituents (70 - 97% biodegradation after 28 days) and is thus expected to be rapidly removed from the aquatic environment via biodegradation. Abiotic hydrolysis is not expected to be relevant for this substance. If present in the atmosphere, Fusel oil is expected to be degraded by photochemical processes (DT50 1.87 to 4.49 days, AOPWIN v1.92).
Due to its physico-chemical properties (log Kow -0.35 - 1.35), bioaccumulation is not expected for Fusel oil.
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.
