Product Overview

Acetone is one of the most widely used industrial solvents and is increasingly used as a chemical intermediate. See Product Uses.
Acetone is low in toxicity. It is a natural product of our body’s metabolism. See Health Information.
Acetone does not cause adverse health or environmental effects at levels typically found in the workplace or environment.
Acetone is extremely flammable with a high vapor pressure; use only with good ventilation and avoid all ignition sources. See Physical Hazard Information.

Product Description

Acetone is a clear, colorless, low-boiling, flammable and volatile liquid characterized by rapid evaporation and a faintly aromatic, sweetish odor.

It readily mixes with most organic solvents and mixes completely with water. However, compatibility should be checked prior to mixing with other solvents or materials.

Product Uses

Roughly 75% of the available acetone is used to produce other chemicals,4 and 12% is used as a solvent. Applications range from surface coatings, films and adhesives to cleaning fluids and pharmaceutical applications. Other consumer and commercial applications include:

* Lacquers for automotive/furniture finishes
* Cellulose acetate films and fibers
* Photographic films and plates casting
* Coatings and inks
* Resin thinners and clean-up operations
* General purpose cements
* Degreasing and degumming agents
* Paint, varnish, lacquer strippers
* Nail polish removers
* Various cosmetic product

Health Information

Acetone has been studied extensively and is generally recognized to have low acute and chronic toxicity if ingested and/or breathed. Breathing high concentrations (around 9200 ppm) in the air caused irritation of the throat in humans in as little as 5 minutes.

Breathing concentrations of 1000 ppm caused irritation of the eye and throat in less than 1 hour; however, breathing 500 ppm of acetone in the air caused no symptoms of irritation in humans even after 2 hours of exposure. Acetone is not currently regarded as a carcinogen, a mutagenic chemical or a concern for chronic neurotoxicity effects

Environmental Information

Acetone is not expected to present a threat to the environment because of its low toxicity, high volatility and complete solubility in water. The intent, however, is to minimize any exposure to the environment from manufacturing and use activities.

Firefighting guidelines should be followed closely. Additional information can be found on the Safety Data Sheet (SDS).

Physical Hazard Information

Acetone is a highly flammable material in both the liquid and vapor forms, has a relatively high vapor pressure, and should be handled only with adequate ventilation and in areas where ignition sources have been removed (e.g. matches and unprotected light switches).
