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 ...
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.
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 ...

Carbon tetrachloride was the first chlorinated solvent to be used in dry-cleaning and was used until the 1950s. [46] It had the downsides of being corrosive to the dry-cleaning equipment and causing illness among dry-cleaning operators, and was replaced by trichloroethylene, tetrachloroethylene [46] and methyl chloroform (trichloroethane). [47]
Wet cleaning refers to methods of professional cleaning that, in contrast to traditional dry cleaning, avoids the use of chemical solvents, the most common of which is tetrachloroethylene (commonly called perchloroethylene or "perc").
