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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 232-395-2 | CAS number: 8013-75-0 A combination of amyl alcohols, primarily isoamyl alcohol and 2-methyl-1-butanol. Other alcohols, acids, esters and aldehydes may also be present.

Description of key information
Fusel oil: soluble / highly soluble
2-methylpropan-1-ol: 85 g/L
3-methylbutan-1-ol: 2.67 g/L
2-methylbutan-1-ol: 3 g/L
Ethanol: 789 g/L
Key value for chemical safety assessment
Additional information
The water solubility of fusel oil is based on a weight of evidence using experimental data for the main components of the substance (ethanol (CAS 64-17-5), 2-methylpropan-1-ol (CAS-78-83-1), 3-methylbutan-1-ol (CAS 123-51-3) and 2-methylbutan-1-ol (CAS 137-32-6)).
Individually, the solubility of the components of fusel oil are soluble (2.67 g/L for 3 -methylbutan-1-ol and 3 g/L for 2-methylbutan-1-ol), or very soluble (789 g/L for ethanol, 85 g/L for 2-methylpropan-1-ol). The fusel oil substance is reported as immiscible / partly miscible, but no quantitative data is available.
The individual solubility of the main components is used to determine the overall solubility of the fusel oil mixture. Depending on the composition of the substance, the substance should be described as either soluble or highly soluble.
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.
