Pentanol Mixture
The pentanol mixture is a multifunctional solvent running 62-68% n-amyl alcohol and 32-38% 2-methylbutanol at 99.0% minimum total content. It works as a solubiliser for coatings, inks, pigments and industrial cleaning agents, as a dispersant and thickener in pigment systems, and as a raw material for fruit chocolate and mint flavourings.
What You Get With This Grade
- Isomer split published as a band with measured results — 64.93% n-amyl and 34.65% 2-methylbutanol

- A single solvent that covers solubilising, dispersing and thickening duties in pigment systems
Technical features
- Multifunctional solvent with applications across many industrial fields
- Total content 99.0% minimum with 99.5% measured
- Colourless liquid with no visible impurities
- Used as an auxiliary material in pharmaceuticals, fine chemicals and food
Where Pentanol Mixture Is Used
Coatings and inks
Used as an excellent solvent in water-based coatings, organic solvent coatings and UV and EB curing coating systems.
Pigment dispersion
Acts as solvent, dispersant and thickener, and helps diffuse pigment molecules to promote dispersion.
Industrial cleaning
An efficient cleaning agent whose polarity lets it remove mixed dirt and oil stains quickly.
Flavours and seasonings
An important raw material for spices and seasonings including fruit, chocolate and mint flavourings.
Chemical synthesis and VOC control
An intermediate for ammonium chloride, ferrous chloride, styrene and fatty acids, and used in VOC control including reducing emissions and odours from plastics or rubber.
How Pentanol Mixture Looks and Ships
Buyers This Grade Is Built For
- Coating and ink makers needing one solvent across water-based, solvent-based and radiation cured systems
- Pigment and ink producers who want solvent dispersant and thickener in one product
- Industrial cleaning formulators
- Flavour houses and fine chemical plants using it as auxiliary material
What It Stops Going Wrong
- Carrying three separate additives for solvency dispersion and thickening complicates the formulation
- Colour in a solvent shows in a white or pastel coating
- Acidity in the solvent attacks pigment stability
- Flammability handling is often underestimated for a mixed alcohol

How It Ships and How to Store It
Packing
- Galvanised iron drum or ISO tank, 165 kg net per drum
- Can be packaged according to user requirements
Storage and transport
- The mixture is flammable — use and storage must follow safe operating procedures to minimise the risk of fire and explosion
- Store away from ignition sources in a ventilated area
How the Lot Is Released
Appearance, total content, both isomer fractions, APHA colour, acidity and water are reported as specification and measured result for each lot.
What We Can Change
165 kg drum or ISO tank, and it can be packaged according to user requirements.
Against the Alternatives
The mixture is the economic solvent choice where the isomer split does not matter. 1-Pentanol is the single straight-chain isomer at 99.80% minimum, used when the downstream ester or flavour requires it. Isoamyl alcohol is the branched isomer for flavour and fragrance work.
Handling Pentanol Mixture on Your Site
Written for the person who receives the drum, not for a brochure.
- Use as solubiliser, dispersant and thickener together rather than adding separate additives
- Follow safe operating procedures for a flammable liquid in use and in store
- Check the APHA colour where the coating is white or pastel
- Move to 1-pentanol where the isomer identity affects the downstream product
