Summary. Acetone evaporates fastest and mixes fully with water. Ethyl acetate sits in the middle: fast evaporation, partial water solubility and a fruity odour. Butyl acetate is slowest, which helps films flow out smoothly. All three are highly flammable. This is general chemistry; the butyl acetate and acetone figures below are not SPC specifications.
Why these three get compared so often
Ink, adhesive and coating formulators often start with the same question: which of ethyl acetate, butyl acetate and acetone gives the drying behaviour I want? All three are common industrial solvents. Ethyl acetate and butyl acetate are esters of acetic acid, while acetone is the simplest ketone. They overlap in what they dissolve, but they differ in how fast they leave a film, how much water they tolerate, how they smell and how they behave around ignition sources.
Everything in this guide about butyl acetate and acetone is general knowledge. Everything stated about ethyl acetate as supplied by SPC comes from our ethyl acetate product page, its Technical Data Sheet and its Safety Data Sheet. For the grade, pack and documents of the other two, use their own product pages on this site.
Side-by-side comparison

| Evaporation speed | Fast | Slowest of the three | Very fast |
| Closed-cup flash point | −4 °C (SDS literature) | about 22 °C | about −20 °C |
| Water solubility | Partial, about 8.7 g per 100 mL at 20 °C | Low, under 1 g per 100 mL | Fully miscible |

Evaporation: the property that decides drying behaviour
Evaporation speed is usually the first filter. A solvent that leaves quickly suits high-speed printing and thin adhesive films, where the film must set in a short time. A slower solvent keeps the film open longer so it can level out and avoid brush marks, orange peel or pinholes.
Acetone is the fastest of the three and is useful where very rapid flash-off is wanted. Ethyl acetate is the common middle choice for gravure and flexo inks and for laminating adhesives. Butyl acetate is slower and is often used as the tail solvent in a lacquer or coating blend so the film flows before it sets.
Blends are normal. Formulators often combine a fast solvent with a slower one to balance drying and flow. One caution from general practice: very fast solvents cool the film surface as they evaporate, and in humid conditions that can pull moisture onto it and cause a cloudy defect called blushing. A slower co-solvent such as butyl acetate is one way to reduce that risk.
Flash point and handling
All three are flammable liquids and need the same basic discipline: no ignition sources, grounded and bonded equipment, good ventilation and a dedicated flammable liquid store. Butyl acetate has the highest flash point of the three, but it is still a flammable liquid and not a safe one.
For ethyl acetate, our Safety Data Sheet records UN 1173, Class 3, Packing Group II, a literature closed-cup flash point of −4 °C, an auto-ignition temperature of 427 °C and explosive limits of 2.0 to 11.5 vol% in air. The occupational exposure limit listed is 400 ppm. Vapours are heavier than air and can travel to a remote ignition source and flash back. Ethyl acetate is incompatible with strong oxidisers, concentrated acids, halogens and strong alkalis. These are literature values from the SDS, not SPC measurements, so ask us (the supplier) if you need them confirmed, and read the full SDS before handling.
Solvency and resin fit
General knowledge, not an SPC specification: all three dissolve a wide range of resins, but not equally. Ethyl acetate is generally regarded as a strong solvent for nitrocellulose, many vinyl and acrylic resins and common adhesive polymers, which is why it features so often in inks, lacquers and laminating adhesives. Acetone dissolves a similar group but evaporates so quickly that it is often used as a cleaning solvent or a fast component of a blend instead of the main carrier. Butyl acetate dissolves many of the same resins more slowly and is valued where the film needs time to level.
General solvent knowledge only goes so far: resin grade, molecular weight and additives all change solubility. Run a small trial in your own formulation before changing a solvent in production.
Water, acidity and residue
Water behaviour differs sharply. Acetone mixes with water in all proportions, so it picks up moisture readily. Ethyl acetate dissolves only some water and can carry a little. Butyl acetate takes up the least. For moisture-sensitive systems, the water figure on the certificate matters more than the solvent name.
Our ethyl acetate TDS limits water to 0.1000% w/w max, acidity as acetic acid to 0.0100% w/w max and residue on evaporation to 0.0100% w/w max. In general, esters can slowly hydrolyse back to alcohol and acid in the presence of water, acids or alkalis, which is one reason acidity and water are controlled. A low residue on evaporation means little non-volatile matter is left behind when the solvent dries, which matters for clean, glossy films.
Choosing by application
- Flexible-packaging and gravure inks: ethyl acetate is a common carrier because it dissolves ink resins and flashes off on the press. Butyl acetate may be added to slow drying where needed.
- Adhesives and lamination: ethyl acetate suits thin-film adhesive application; the right balance of speed and open time depends on your line speed.
- Nitrocellulose lacquers and coatings: a blend of fast and slow solvents is typical, with ethyl acetate as the active solvent and butyl acetate as a slower component.
- Pharmaceutical process use: ethyl acetate is used as an extraction solvent. SPC's grade is commercial / industrial; it is not a pharmacopoeial grade, so check your own requirement first.
- Cleaning and rapid flash-off: acetone is the usual choice.
- Aromatic or alcohol alternatives: see toluene for aromatic solvency and isopropyl alcohol (IPA) for an alcohol solvent.
What SPC lists for ethyl acetate
Supreme Petro Chemicals is a Chennai trader, importer and bulk distributor, not a manufacturer. For ethyl acetate we list Commercial / Industrial Grade at 99.80% w/w min, CAS 141-78-6, HSN 2915 31 00, UN 1173. The pack is the bulk tanker, dispatched from our Redhills warehouse across South India. The Technical Data Sheet (SPC-TDS-EST-001) names Laxmi Organic Industries Ltd, Satyam Petrochemicals and Jubilant Ingrevia Limited as the producers, and a batch Certificate of Analysis is supplied with every delivery. It is industrial grade only, not food grade or pharma grade.
