Processing Methods & Reference Formulations
A. Perfume
Use at very low levels (0.1–1%), as it has a sharp, fusel-like odor but can boost the diffusiveness of fruity and green notes. Add during the initial blending phase with other aroma chemicals before dilution with alcohol.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Isoamyl Alcohol | 0.1% |
| Linalool | 15% |
| Benzyl Acetate | 10% |
| Phenylethyl Alcohol | 10% |
| Hexyl Cinnamic Aldehyde | 10% |
| Hedione | 10% |
| Iso E Super | 15% |
| Galaxolide | 10% |
| Musk Ketone | 5% |
| Dipropylene Glycol (DPG) | 15% |
B. Detergents
Use at low levels, mainly as a fragrance booster or solvent to enhance the lift of fruity or green top notes. Add during the final blending phase, after cooling, to minimize evaporation and preserve volatile aroma.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Sodium Linear Alkylbenzene Sulfonate (LAS) | 18% |
| Alcohol Ethoxylate | 8% |
| Sodium Carbonate | 5% |
| Sodium Citrate | 5% |
| Enzyme Blend (Protease, Amylase) | 0.5% |
| Polyacrylate | 1% |
| Fluorescent Whitening Agent (e.g., Tinopal CBS-X) | 0.2% |
| Methylisothiazolinone | 0.2% |
| Fragrance composition | ~1.5% |
| Isoamyl Alcohol | 0.15% |
| Water | ~60-70% |
C. Cosmetic lotion
Use at low levels, as it has a strong odor and functions mainly as a fragrance enhancer or solvent. Add during the cool-down phase, to preserve its volatility and prevent unwanted scent changes.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Water | ~75% |
| Glycerin | 5% |
| Cetearyl Alcohol | 3% |
| Glyceryl Stearate | 2% |
| Caprylic/Capric Triglyceride | 5% |
| Isoamyl Alcohol | 0.01% |
| Dimethicone | 3% |
| Phenoxyethanol + Ethylhexylglycerin | 1% |
| Carbomer | 0.3% |
| Triethanolamine | 0.2% |
| Tocopherol (Vitamin E) | 0.5% |
| Fragrance (optional) | ~2% |

About Iso Amyl Alcohol
Iso amyl alcohol - also called isopentyl alcohol or 3-methyl-1-butanol (CAS 123-51-3, C₅H₁₂O) - is a colourless liquid with a characteristic fusel and fruity odour. It is the main isomer of amyl alcohol, the C5 alcohol family, and a natural fusel by-product of fermentation.
Its two big roles are as a solvent and as the chemical intermediate used to make the isoamyl ester family - most famously iso amyl acetate (banana oil). Note that it is not the same as isopropanol (IPA): isopropanol is a C3 alcohol used mainly for cleaning and disinfection, while iso amyl alcohol is a larger C5 alcohol used as a solvent and ester precursor.
Iso Amyl Alcohol Suppliers, Manufacturers & Distributors
Elchemy is a trusted iso amyl alcohol supplier, manufacturer partner and distributor, supplying isopentyl alcohol to flavour and fragrance houses, chemical, pharmaceutical and laboratory buyers across the USA, UK, UAE and 40+ countries. Working with audited manufacturers across multiple origins, we deliver high-purity (≥99%) material with a Certificate of Analysis on every batch.
Buy Iso Amyl Alcohol in Bulk
Elchemy supplies bulk iso amyl alcohol from laboratory quantities to drums, IBCs and tankers, in technical, flavour/fragrance and reagent grades, with US domestic stock for faster delivery. Tell us your grade, purity and volume for a fast quote.
Iso Amyl Alcohol Price: Bulk Pricing & Price per Litre
The iso amyl alcohol price moves with feedstock and grade - technical versus high-purity - along with volume and origin, so Elchemy quotes live rather than publishing a fixed rate.
Buyers benchmark the price per litre or per kg for small lots and the per-drum or per-MT rate for contracts. Request a quote on the quote form for an exact figure within 24–48 hours.
Iso Amyl Alcohol Manufacturing Process
Iso amyl alcohol is obtained either by fractional distillation of fusel oil, a by-product of ethanol fermentation, or synthetically via the oxo process (hydroformylation of butenes) followed by hydrogenation.
The crude alcohol is distilled to ≥99% purity. Raw materials are fusel oil or butene and synthesis gas feedstock. Every batch Elchemy supplies is tested for assay, acid value and moisture, with a COA per order.
Grades Available
- Technical / Industrial (≥98%) - solvent, ester synthesis and mining frother
- Flavour & Fragrance, FEMA 2057 (≥99%) - flavours and perfumery
- Reagent / Laboratory (≥99%) - DNA and RNA extraction, and analysis
- Pharmaceutical (high purity) - pharmaceutical synthesis intermediate
Buy Iso Amyl Alcohol in Bulk - Packaging & Logistics
Iso amyl alcohol ships in drums, IBC totes and ISO tankers, packed and transported under dangerous-goods rules as a flammable liquid (UN 1105, Class 3).
US domestic stock supports faster fulfilment. Material from other origin countries typically transits 24–28 days to the US East Coast, on FOB, CIF or DDP terms. Store in tightly closed containers in a cool, ventilated, flame-proof area away from heat, sparks and oxidisers.
Why Choose Elchemy as a Trusted Iso Amyl Alcohol Supplier
- Multiple grades - technical, flavour and fragrance (FEMA 2057) and reagent or lab grades from one partner
- Full documentation - COA, TDS and GHS SDS with every order; FEMA/IFRA and origin declarations on request
- Samples in 24–48 hours - qualify grade and purity before any bulk order
- Ester-chain sourcing - source the alcohol and its downstream esters together, with tailored grades via custom manufacturing
Safety & Handling
Iso amyl alcohol is a flammable liquid (flash point around 45 °C, UN 1105, Class 3) and can irritate the eyes, skin and respiratory tract; high vapour exposure may cause headache, dizziness or nausea.
Handle with gloves and goggles in a ventilated area away from ignition sources, and flush with water on contact. It is GRAS as a flavouring at low levels but should be handled as an industrial chemical in concentrated form. A full GHS-aligned SDS ships with orders.
- Fruity, Sweet Scent: Offers a subtle, sweet aroma with an alcoholic note, enhancing fragrance formulations.
- Versatile Ingredient: Works well in both perfumes and flavoring products due to its mild scent.
- High Purity: Maintains a clean, consistent fragrance release across different applications.
- Sustainable Production: Produced using eco-friendly methods to minimize environmental harm.
- Blends Seamlessly: Combines well with other fruity and floral notes for balanced fragrances.
