Specification, TDS & SDS (PDF) ↓
Bio-based isoamyl alcohol (3-methyl-1-butanol) is obtained by distillation from fusel oil – a by-product of bio-ethanol fermentation from renewable raw materials. It is chemically identical to petrochemically produced isoamyl alcohol and suitable as a direct drop-in replacement without reformulation.
Isoamyl alcohol is a colourless, clear liquid with a characteristic odour and good solvency for resins, oils and nitrocellulose. As a building block for isoamyl acetate and other esters it is a key raw material for the flavour and fragrance industry.

This chain – sugarcane and ethanol production, fusel oil recovery and transport, distillation – is covered by the life cycle assessment (cradle-to-gate).
A life cycle assessment according to ISO 14040/14044 is available for our bio-based isoamyl alcohol (cradle-to-gate, European Commission Environmental Footprint method EF 3.1). The study was prepared by ACV Brasil on the basis of primary data from the manufacturer (production period July 2023 to June 2024). The product carbon footprint covers sugarcane and ethanol production, fusel oil recovery and transport, and distillation to isoamyl alcohol.
Study data & methodology
Base scenario: fossil emissions without crediting biogenic carbon. The biogenic CO₂ content of 2.5 kg CO₂/kg is reported as additional information and may only be credited where the carbon remains permanently bound in the end product. Study version 1.1 (March 2025), internally reviewed; external critical review not yet completed – the results are not intended for comparative assertions against other products.

FAQ: Isoamyl alcohol
How is bio-based isoamyl alcohol obtained?
By distillation of fusel oil, a by-product of ethanol fermentation from sugar cane. The isoamyl alcohol is chemically identical to petrochemical material and replaces it without reformulation.
Is life cycle data available for my Scope 3 reporting?
Yes. A life cycle assessment according to ISO 14040/14044 (cradle-to-gate, EF 3.1) is available for our isoamyl alcohol. Key figures and the full report are available on request.
Which documents can I download?
The specification, technical data sheet and safety data sheet are available on this page as PDFs in German and English. The certificate of analysis comes with every delivery.
Why does an IBC hold only 800 kg?
Isoamyl alcohol has a density of around 0.81 g/cm³. A 1,000 l IBC therefore holds about 800 kg and a steel drum about 170 kg; an ISO tank carries approx. 18,000–20,000 kg.
