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).
