A very important derivative is ethylene glycol which is used for the manufacture of polyester fiber for clothes, upholstery, carpet, and pillows and the blending of automotive engine antifreeze. The ethylene oxide used to sterilize medical products or treat spices is less than 0.5% of the total amount of EO produced in the United States.

Ethylene oxide is a versatile and valuable compound that’s used to help make countless everyday products.

EtO is also known as “epoxitane” or “dimethylene oxide.” It is a colorless gas and reacts with several chemicals, such as alcohols, amines, organic acids and amides. �0���i�epG�0�쀈2l0 � C 0000005929 00000 n EtO is a toxic gas that causes an internal chemical reaction in the microorganisms, which is generally ascribed to alkylating functional groups of enzymes, other proteins, and nucleic acids (Bruck and Mueller, 1988).

EO has sterilized many polymers that could not be irradiated or heat sterilized. There may be some sensitivity to humidity, such as hydrophilic coatings, but there are typically solutions to this type of problem. While that fire or explosion would probably kill all living microbes, it would also destroy any equipment it was trying to sterilize and would kill you as well. These side effects will be discussed in just a little bit. © copyright 2003-2020 Study.com. An error occurred trying to load this video.

S. Lerouge, in Metals for Biomedical Devices, 2010. When properly performed, EtO has been shown to effectively sterilize the interface of assembled modular components, such as metal-backed tibial and patellar devices [23]. credit-by-exam regardless of age or education level. You jump into your car, turn the ignition key and it starts immediately, despite the winter cold. Ethylene oxide is used to make a variety of products found all around your house – from shampoos to disinfectants to laundry detergent. At higher temperatures, especially above 50 degrees Fahrenheit, and stronger winds, we would expect ethylene oxide to transport farther away from the emission source more effectively.

The exact amount of CO2 emissions associated with the ethylene oxide production is not easily available in the literature. Services. Author: WXIA Staff What should I do if I smell ethylene oxide. endstream endobj 140 0 obj <>/Filter/FlateDecode/Index[5 97]/Length 22/Size 102/Type/XRef/W[1 1 1]>>stream Ethylene oxide can last in the air for weeks and can be transported with prevailing winds. Ethylene is the raw material used in the manufacture of polymers such as polyethylene (PE), polyethylene terephthalate (PET), polyvinyl chloride (PVC) and polystyrene (PS) as well as fibres and other organic chemicals. While ethylene oxide does dissolve in water, it can also evaporate from water back to the air. It also helps manufacture medications that better deliver needed treatments to patients. This is a process whereby a hydrogen atom is replaced by an alkyl group. Very thin tubing may present compatibility issues. The Lautenberg Chemical Safety Act updated TSCA to protect Americans' health and our environment, and supports economic growth and manufacturing in the U.S. ©2005-2020 American Chemistry Council, Inc. It is a colorless, poisonous gas that attacks the cellular proteins and nucleic acids of microorganisms. imaginable degree, area of Not sure what college you want to attend yet? Adjusting these parameters according to the load can optimize the sterilization process. It is also used as a fumigant for textiles and for sterilization, especially for surgical instruments. {{courseNav.course.topics.length}} chapters | Again, an autoclave, which uses moist heat at a high temperature to sterilize things, would ruin moisture sensitive equipment, but ethylene oxide can be safely used for materials and equipment that are sensitive to moisture. Artem has a doctor of veterinary medicine degree. and career path that can help you find the school that's right for you. 0000004459 00000 n Based on your general understanding of organic chemistry, The use of gaseous agents like ethylene oxide when heat or moisture is a problem in controlling microbes is which of the following? 0000286323 00000 n ​Like all air pollutants, ethylene oxide (EtO) disperses in the air, with the speed of dispersal depending on the strength of winds. The gas I'm talking about is called ethylene oxide.

Ethylene oxide (EO) gas sterilisation is widely used in the biomedical industry as well as in health-care centres, especially for temperature-sensitive materials. credit by exam that is accepted by over 1,500 colleges and universities. 0000290272 00000 n What is ethylene oxide's half-life in air? All these things are made possible by using products created from ethylene oxide. 102 0 obj <> endobj

Ethylene oxide is used as a fumigant for spices, seasonings, and foodstuffs and as an agricultural fungicide.

EPA has not conducted studies to determine the role that plants play in levels of ethylene oxide emissions. From: Clinical Engineering Handbook, 2004, W.J.
