Tetrachloroethylene, also known as perchloroethylene [a] or under the systematic name tetrachloroethene, and abbreviations such as perc (or PERC), and PCE, is a chlorocarbon with the formula Cl 2 C=CCl 2. It is a non-flammable, stable, colorless and heavy liquid widely used for dry cleaning of fabrics.
The exposure to tetrachloroethylene in a typical dry cleaner is considered far below the levels required to cause any risk. [11] It is estimated that 50% to 70% of dry cleaners in the US were using PCE as of 2012. [7] Alternative solvents are available, but these may require major changes in equipment, procedures, and operator training. [7]
Two carcinogenic chemicals used in cleaning products and other common household goods have been banned in the U.S., the Environmental Protection Agency (EPA) announced in a Dec. 9 press release ...
Tetrachloroethylene oxide, perchloroethylene oxide (PCEO) or tetrachlorooxirane, is the perchlorinated analogue of ethylene oxide and a proposed metabolite of tetrachloroethylene. [3] It is a halogenated epoxide with the formula C 2 Cl 4 O. Tetrachloroethylene oxide is fairly stable but rearranges to trichloroacetyl chloride at higher ...
The handling of this chemical may incur notable safety precautions. It is highly recommended that you seek the Material Safety Datasheet for this chemical from a reliable source such as SIRI, and follow its directions.
Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent.It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9]

Between 1975 and 1985, the water supply of Marine Corps Base Camp Lejeune was contaminated with trichloroethylene and other volatile organic compounds. [10]In 1986, and later again in 2009, 2 plumes containing trichloroethylene was found on Long Island, New York due to Northrop Grumman's Bethpage factories that worked in conjunction with the United States Navy during the 1930s and 1940s.
