Ethylene oxide (also known as EO or EtO) is a low temperature gaseous process widely used to sterilize a variety of healthcare products, such as single-use medical devices. At room temperature (25 C) and normal atmospheric pressure, ethylene oxide is a colourless, highly reactive, and flammable gas with a characteristic ethereal odour. However, the additional surface tension reduction in the high polymer concentration regime depends strongly on the molecular weight. About Ethylene. EtO is found in the production of solvents, antifreeze, textiles, detergents, adhesives, polyurethane foam, and pharmaceuticals. CofA. The EtO scrubbing system is based on absorption of ethylene oxide and its subsequent hydration to ethylene glycol. At room temperature (25 C) and normal atmospheric pressure, ethylene oxide is a colourless, highly reactive, and flammable gas with a characteristic ethereal odour.
